Do you have a repro? I have a project with log4j under bloop, works fine for me. Maybe some specific dependency setting?

[pkolaczk]

This project doesn't have log4j in its dependencies. Why should it have? It looks like the exception is coming from bloop, so if bloop uses log4j it should put it on the classpath.

This problem doesn't happen on all my subprojects - I'll try to find what is different.

[pkolaczk]

Adding log4j to the dependencies of the project helped.

However I don't want to do that, because the project compiles fine in gradle without it.
gradlew dependencies on that project doesn't show log4j anywhere. There are slf4j dependencies only.

@pkolaczk What do you have in the scala jars configuration field?

You should only have the jars of the scala artifacts (library, reflect, compiler) + jline. If that's fine, then I guess there's nothing we can do here until we have a small reproduction. I don't understand why this is happening, the error comes indeed from bloop, as if some dependency in your project was being picked over a dependency in bloop. The only case I can think of where this could happen is if there were some unexpected dependencies in the scala.jars field of your JSON file.

[pkolaczk]

There is no scala section at all, only java section:

        "out" : "/home/pkolaczk/Projekty/xxxxxxxxxxxxxxxxx/build",
        "classesDir" : "/home/pkolaczk/Projekty/xxxxxxxxxxxxxxxxxxx/build/classes",
        "resources" : [
            "/home/pkolaczk/Projekty/xxxxxxxxxxxxxxxxxxxxxxxxxx/src/main/resources"
        ],   
        "java" : {
            "options" : [
                "-target",
                "1.8",
                "-source",
                "1.8",
                "-encoding",
                "UTF-8",
                "-g",
                "-sourcepath",
                "-proc:none",
                "-XDuseUnsharedTable=true"
            ]
        },
        "platform" : {
            "name" : "jvm",
            "config" : {
                "home" : "/opt/jdk1.8.0_201",
                "options" : [
                ]
            },
            "mainClass" : [
            ]
        },
        "resolution" : {

This is a Java-only module.

[jvican]

It's likely the issue here is the resources. I guess you have a resource file configuring slf4j to use log4j, right? We add the resources to the compile classpath so that might be the reason why this is failing.

[pkolaczk]

There are no resources in this project.
But maybe there are resources in some of the dependency jars?

[jvican]

Yes, that's the most likely. A reproduction here would be useful. If we confirm this is the case, the fix would probably be to whitelist the access to log-related resources (log4j, jul) from the compiler classloader owned by Zinc. But it's weird that this is not happening in Gradle itself, I wonder if I'm missing something or there's some special configuration of your project in the Gradle build.

[schleumer]

I don't know if related, but somehow i'm getting "Unexpected error when compiling", but mine is about java.sql:

Unexpected error when compiling projectName: 'java/sql/ResultSetMetaData' 

I can't create a repro now, but i can relate that i'm using Slick with PostgreSQL and SBT 1.2.8, also it's Scala 2.12.8 and JDK12.

[jvican]

@schleumer Interesting. Would be lovely if you can provide a repro and I can look into this, your error seems to suggests this issue isn't caused solely with resources! In the meanwhile I'm closing this ticket until we have something actionable.

[schleumer]

@jvican, done that! https://github.com/schleumer/bloop-repro-957

I've tracked something and seem that it may be some macro related problem, if you find that it's something with slick, i will report to them.

[schleumer]

Just for report, worked in:
✅ OpenJDK8
❌ OpenJDK10
❌ OpenJDK11
❌ OpenJDK12

Somehow worked on Oracle's JDK12(only on MacOS) 🤔

[nafg]

I'm having the same error as @schleumer

[nafg]

...and switching the bloop server from java 10 to 8 worked (via sudo update-alternatives --config java)! Thanks reporting that factor!

[rtar]

I wonder if anyone found workaround for this as it is effectively blocking Slick development using Bloop on JDK11.

[jvican]

I’ll be looking into it and will keep you updated @rtar

[jvican]

I've done some progress understanding what's going on here, I think it's related to the fact that we don't use the same bootclasspath in JDK 8 than JDK 11.

Here's the bootclasspath in JDK 8:

    /usr/lib/jvm/java-8-graal/jre/lib/resources.jar:/usr/lib/jvm/java-8-graal/jre/lib/rt.jar:/usr/lib/jvm/java-8-graal/jre/lib/sunrsasign.jar:/usr/lib/jvm/java-8-graal/jre/lib/jsse.jar:/usr/lib/jvm/java-8-graal/jre/lib/jce.jar:/usr/lib/jvm/java-8-graal/jre/lib/charsets.jar:/usr/lib/jvm/java-8-graal/jre/lib/jfr.jar:/usr/lib/jvm/java-8-graal/jre/lib/jvmci-services.jar:/usr/lib/jvm/java-8-graal/jre/classes:/usr/lib/jvm/java-8-graal/jre/lib/boot/graaljs-scriptengine.jar:/usr/lib/jvm/java-8-graal/jre/lib/boot/graal-sdk.src.zip:/usr/lib/jvm/java-8-graal/jre/lib/boot/graal-sdk.jar:/home/jvican/.ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.12.8.jar

Here's in JDK 11:

    /home/jvican/.ivy2/cache/org.scala-lang/scala-library/jars/scala-library-2.12.8.jar

I need to figure out why that's not the case. I'll keep you updated.

[jvican]

Alright, I think I have a fix. If successful will open PR soon.

[jvican]

Alright @schleumer your issue is now fixed, a fix will be soon available in master. The original issue you reported and the one @pkolaczk are fundamentally different, I think @pkolaczk's is related to the compilation engine while yours it's related to a patch we were missing to fully support Java platforms greater or equal than 9.

I'm nonetheless going to mark the fix for this issue as a fix for this ticket. I believe @pkolaczk's issue will be fixed in latest master given some unrelated changes I've done in the compilation engine. If that's not the case, then we can create a new ticket, find a way to repro the issue and find out what's missing.
