Lombok: Lombok not working with JDK 11 modules (Jigsaw)

[arana198]

I'm using:

• Java 11
• Lombok 1.18.4 (also tried 1.18.5 edge)
• Gradle 5.0 (also tried with 4.9)

PS: I have requires static lombok in module-info.java and IDE does not show any error

I also have included the requires static lombok; in my module-info.java

EDIT: code can be found here: https://github.com/jython234/matrix-bridge-java

[dasAnderl]

same issue here java 10, lombok 1.18.0, mvn, module info with requires lombok
i get.

/Users/dasanderl/dev/workspaces/idea/MOD-TEST/MOD-Config/src/main/java/module-info.java:[2,18] module not found: lombok

[mahit777]

faced the same issue looks like it also depends on maven-compiler plugin because I've seen some posts that claim that they could resolve this issue by updating the version of maven-compiler. but none of them worked for me what worked was I was using mapstruct as an annotationPocessrPath the issue was gone when I removed that

[FortBlox]

same issue here java 10, lombok 1.18.0, mvn, module info with requires lombok
i get.

Same problem. Only for me maven says that "org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile failed".
Tried downloading the edge version, still no luck. Anybody knows if/when Lombok will support Java modules?

[randakar]

Current edge release has support, according to
https://projectlombok.org/setup/javac

[schoettner]

I can confirm this. I included the edge release (JDK 10, Gradle 4.9) and everything was working again as it used to with JDK 8

[markusjevringgoeuro]

When I use the latest version (1.18.2, there was no edge release when I checked), and "requires static lombok;" in my module-info.java file, when the actual code generation stops working. It doesn't generate my getters and log fields etc. I'm using maven 3.5.2, and IntelliJ IDEA. Neither of them (idea with the lombok plugin) triggers the generation of the code. Alternatively, it's triggered but it fails silently.

[FortBlox]

I was a bit busy, so only got to play around with it today. There is currently no edge release, looks like that release went on to become version 1.18.2. I tried using this version, added a "requires static lombok" to the module-info, unfortunately it didnt work. I am using java 10 modules with maven and intelliJ. It works ok if I just use java 10 without modularizing the project, but as soon as I add a module-info file, lombok stops generating the classes.

[alejzeis]

Somewhere it was mentioned that Lombok isn't on the module path as it
doesn't have a module-info.java file. So whenever it is used by a
modularized project it won't work as Java searches for lombok on the module
path instead of the class path. I think that may be the issue.

[MCMicS]

same here. After create module-info the compilation not work with latest lombok version.
simple example: https://github.com/MCMicS/simple-lombok

• branches with annotationprocessor, non-modulized

Hope anyone has a solution. I will look also for one

if yout add follwoing to maven-compile-plugin yout got a different error:

                        <annotationProcessorPaths>

IntelliJ wil show following warning (with annotation processer in pom):
Warning:java: Can't force a new processing round. Lombok won't work.

But the compilation will success.

[MCMicS]

Update from 2018-07-31
I tried to compile by hand and compare with maven build.
If you use javac -cp lombok.jar -p lombok.jar <source> you will get the exception wiht javax.annotation.processing.FilerException: Cannot write to the given module.

The maven compiler is calle without classpath for lombok and so the compiler not found the lombok methods:

Application.java:11: error: cannot find symbol
log.info("Sample Title: " + sample.getTitle());

with annotationProcesser config within pom, the -processorpath will be set to lombok.

In my opinion we should tak ok at the javax.annotation.processing.FilerException which is raise from lombok module.

And another look should be to the compile plugin. Why is no classpath is set like the documentation says: https://projectlombok.org/setup/javac

[MCMicS]

The maven compiler works correct to my mind because lib with modules should be only occurred in modulepath. But the annotation processers are looked up within the the classpath. So we need the setting:

<annotationProcessorPaths>
   <path>
     <groupId>org.projectlombok</groupId>
     <artifactId>lombok</artifactId>
     <version>${lombok.version}</version>
   </path>
</annotationProcessorPaths> 

There is also a discussion with annotaion processor not used if specified in module-path: http://jigsaw-dev.1059479.n5.nabble.com/Annotation-processors-and-the-processor-module-path-td5714320.html

any progress with the FilerException?
Maybe related Bug:
https://github.com/rzwitserloot/lombok/issues/1572

[MCMicS]

I tried with edge version (1.18.3).
But now I get an additional compile error:

if I try Java11 and annotationProcessor Path I will get somer errer for mapstruct:

[gestshb]

i have the same problem (maven 3.5.2/jdk10/intellij 2018.2 /lombok 1.18.2) plug-in lombok installed
any solution ?

[schoettner]

Another workaround is to change the compiler plugin. Because I use Groovy for testing I had limited choice what plugins to use. The groovy-eclipse-compiler does not seem to work at the moment (it worked with the lombok 1.18.0-edge). For the gmaven-plus plugin I compiled a custom hotfix to support jdk10 and uploaded it to an internal jFrog. The fixed version of gamaven-plus works perfectly fine with all lombok versions.

[SvenWoltmann]

I found ... not a solution but rather a hack ... to get this running with Maven and JDK 9 / 10.

So first you have to add the annotation processor path, as already mentioned before:

<annotationProcessorPaths>
   <path>
     <groupId>org.projectlombok</groupId>
     <artifactId>lombok</artifactId>
     <version>${lombok.version}</version>
   </path>
</annotationProcessorPaths> 

Now I also get the _"/lombok/dummy/ForceNewRound0 ... file should be on source path"_ error.

To fix this, I analyzed which parameters Maven passes to javac and reproduced the compilation process by directly calling javac.

I first found out that it works if you remove the "-sourcepath" parameter. However, that should not and cannot be done with Maven.

After another day of experiments, I found out that it also works if you add "/" (I assume that's where the _/lombok/dummy/ForceNewRound0.java_ file is written to) to the sourcepath.

And that can be done with Maven ... although it's kind of hacky:

You need to add to the _maven-compiler-plugin_ the following compiler arguments:

<compilerArgs>
    <arg>-sourcepath</arg>
    <arg>${project.basedir}/src/main/java${path.separator}${project.basedir}/target/generated-sources/annotations${path.separator}/</arg>
</compilerArgs>

This doesn't really replace the "-sourcepath" compiler argument, but it adds a second "-sourcepath", which overwrites the first one.

As I said, this is not a clean solution, but it works and maybe it's a starting point to find a real solution.

[SvenWoltmann]

Unfortunately my previous hack breaks the build in IntelliJ IDEA with javac when the project contains tests:

• "module not found" error for each module referenced from module-info.java
• "file should be on source path" error for each of my tests

It builds in Eclipse and in IntelliJ with the Eclipse compiler. I'll try to find a solution...

[SvenWoltmann]

Here's a way to get the hack running in Maven, IntelliJ and Eclipse:

I define the sourcepath in a separate Maven profile "update-sourcepath-for-lombok", so it's ignored by IntelliJ:

<build>
  <plugins>
    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.0</version>

      <configuration>
        <annotationProcessorPaths>
          <path>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>${lombok.version}</version>
          </path>
        </annotationProcessorPaths>
      </configuration>
    </plugin>
  </plugins>
</build>

<profiles>
  <profile>
    <id>update-sourcepath-for-lombok</id>
    <build>
      <plugins>
        <plugin>
          <artifactId>maven-compiler-plugin</artifactId>

          <configuration>
            <compilerArgs>
              <arg>-sourcepath</arg>
              <arg>${project.basedir}/src/main/java${path.separator}${project.basedir}/target/generated-sources/annotations${path.separator}/</arg>
            </compilerArgs>
          </configuration>
        </plugin>
      </plugins>
    </build>
  </profile>
</profiles>

And when running Maven on the command line, I activate that profile:

mvn -Pupdate-sourcepath-for-lombok clean package

[MCMicS]

like @SvenWoltmann mentioned the sourcepath is the problem. But if I try it with my own Annotation processors it works also with this flag. I will have a deeper look in lombok code the days.

[MCMicS]

@rzwitserloot The problem ist that the EmptyLombokFileObject ist created and root. So the compiler warns because the root is not in source-module-paths.
Why not use the target or temp folder for ForceNewRound files?
Or maybe one of them ideas:

• add some logic in Javac9BaseFileObjectWrapper
• use some kind of SourceMemoryJavaFileObject

Log from lombok.javac.apt.InterceptingJavaFileManager#getJavaFileForOutput I've added:

warning: getJavaFileForOutput javaFileObject: /lombok/dummy/ForceNewRound0.java
warning: getJavaFileForOutput javaFileObject: file:///lombok/dummy/ForceNewRound0.java

In newer version for com.sun.tools.javac.processing.JavacFiler#createSourceOrClassFile you will find an implementation for module handling too.

[MCMicS]

Tried with latest Edge Release (1.18.3 (2018-10-15 22:58:24 UTC) )

No resolution. Lombok only work in test classes in IntelliJ. Maven still fails

Is this a known issue? If yes do we have an ETA when it will be fixed?

Unfortunately it's blocking my organization to move to a modularized project structure.

Cheers,
Mate

[ipkpjersi]

Issue is still present with Java 11 and Lombok 1.18.4 and Gradle 4.10.2, I guess I'll check back in a year after Java 12 has been out for a while and hope it's fixed by then. Cheers.

[arana198]

Has anybody got this to work any version of Java/Lombok that allows modules?

[megha0703]

let me know sa well

[teppah]

Does anybody have a solution to this yet?

[micheljung]

Are there any plans to fix this?

[dandudzi]

I changed to lombok version 1.18.2. see: https://github.com/rzwitserloot/lombok/issues/2028

[rspilker]

We're working on this.

[rspilker]

We just released an edge release. Can you give it a try and report back:

• if it fixes the problem
• if everything else still works as expected

[MCMicS]

After a short test it seems to be fixed. Compiling with Maven works and Intellij also compile the source files correctly.

Tested with JJDK 11 and JDK 12

I'll will try a wider test later this day.
Thanks for fix so far.

-- Addional comment--
if you remove the annotation processor configuration from pom then the lombok module is not found.
Maybe it is another problem to solve. If you configure the annotation path then it will work with maven on terminal or in IDE.

Hey,
using edge release I get lombok to work with Java 10 and Jigsaw modules. When building project with mvn clean package and running it with java -jar ... it works great.

But on the other hand run from IntelliJ fails with error:

/usr/lib/jvm/java-11-openjdk-amd64/bin/java -javaagent:/home/radzik/.local/share/JetBrains/Toolbox/apps/IDEA-U/ch-0/183.5429.30/lib/idea_rt.jar=43289:/home/radzik/.local/share/JetBrains/Toolbox/apps/IDEA-U/ch-0/183.5429.30/bin -Dfile.encoding=UTF-8 -p /home/radzik/Documents/lomboktest/target/classes:/home/radzik/.m2/repository/org/projectlombok/lombok/edge-SNAPSHOT/lombok-edge-20190129.004558-1.jar -m lomboktest/com.example.App
Error occurred during initialization of boot layer
java.lang.module.ResolutionException: Module lombok does not read a module that exports org.mapstruct.ap.spi

Should it be solved in this edge release or am I doing something wrong?

@gvart The surefire plugin works for me if I configure forkCount as zero instead of the default value of 1:

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M3</version>
    <configuration>
        <!-- needed so that lombok does not throw errors during tests -->
        <forkCount>0</forkCount>
    </configuration>
</plugin>

[pavanjava]

taking the lombok edge version i have resolved the issue. below is the config i have used

org.apache.maven.plugins
maven-compiler-plugin
3.8.0

10


org.projectlombok
lombok
${lombok.version}





org.ow2.asm
asm
6.2

[vrapalis]

Hello all,

in my company we want migrate from java 8 to java 12.
Can i use at the moment lombok in gradle based project with java 12? Thanks a lot.

Best Regards.

[pentos9]

upgrade your Lombok version, try this:

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.6</version>
</dependency>

v1.18.6 and above support JDK10/11

[ipkpjersi]

As I mentioned above, issue is still present with v1.18.4. Cheers.

edit: the comment above originally said v1.18.4 but has since been edited to v1.18.6, however I looked through the patch notes of v1.18.6 and saw no mention of illegal reflective access being fixed.

yes,i change the version.it is ok when i upgrade to v1.18.6

[rzwitserloot]

sounds like this is fixed.

[GedMarc]

@rzwitserloot What fixed it? Still happening???!?
I've had to delombok every single one of my projects cause of this - is there any eye to fix the processing in maven?

[christian-schlichtherle]

I'm facing the same issue, so it's definitely not fixed:

OpenJDK 11.0.2
Lombok 1.18.10

I'm going to delombok my project.

[noguespi]

Got the same issue usings jdeps (but I'm not going to delombok my project :D ).

Error: Module lombok does not read a module that exports org.mapstruct.ap.spi
jdeps failed

I haven't enough knowledge of the new java module system, I just excluded the lombok jar from jdeps analysis and fortunately it uses modules probably required by other modules. My goal is to list all the modules and build a minimal jvm runtime with minimal number of modules.

[GedMarc]

Ok so I did get it, in JDK 12 it changes as well because service loaders are no longer read from the META-INF location anymore, only from the module file

what you want to do is

Then in your module-info file,

requires static lombok;

[GedMarc]

No I have Lombok fully supported and installed on 1.18.12 from jdk11 all the way through to jdk14.

Double check your config and make sure you are referencing the Lombok annotation processor in your maven compiler config.

It will not automatically pick up the annotation processor, especially from 12 and up as the meta-inf/services directory can longer be referenced at all for service discovery.

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>

Hello, I am also still having errors using lombok 1.18.12 from OpenJDK11. I've tried the solutions above but it still does not work.

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <source>11</source>
        <target>11</target>
        <compilerVersion>11</compilerVersion>
        <annotationProcessorPaths>
            <annotationProcessorPath>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>1.18.12</version>
            </annotationProcessorPath>
            <path>
