Error-prone: Is there any way to control using error-prone or not when compile my maven project?

[mandy4321]

such as add some compile arguments when I run "mvn compile", maybe sometimes I just want to use jdk to compile my project.

Hello!

I think the easiest way to control this in Maven is to use a maven profile to wrap the error prone configuration:

<profiles>
  <profile>
   <id>errorprone</id>
     <build>
       <plugins>
         <plugin>
           <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-compiler-plugin</artifactId>
           <version>3.3</version>
           <configuration>
             <compilerId>javac-with-errorprone</compilerId>
             <forceJavacCompilerUse>true</forceJavacCompilerUse>
             <!-- maven-compiler-plugin defaults to targeting Java 5, but our javac
                  only supports >=6 -->
             <source>7</source>
             <target>7</target>
           </configuration>
           <dependencies>
             <dependency>
               <groupId>org.codehaus.plexus</groupId>
               <artifactId>plexus-compiler-javac-errorprone</artifactId>
               <version>2.8</version>
             </dependency>
             <!-- override plexus-compiler-javac-errorprone's dependency on
                  Error Prone with the latest version -->
             <dependency>
               <groupId>com.google.errorprone</groupId>
               <artifactId>error_prone_core</artifactId>
               <version>2.0.14</version>
             </dependency>
           </dependencies>
         </plugin>
       </plugins>
     </build>
  </profile>
</profiles>

Then run:

mvn clean compile -perrorprone to activate the profile from the command line. The clean is needed because if maven sees up-to-date compiled artifacts from the last non-errorprone build, then it won't attempt a recompile.

It works very well, thank you so much! And my command line is "mvn clean compile -P errorprone".
