- Version: @VERSION@ | changelog -

- ecj (the eclipse standalone compiler) is compatible with lombok. Use the following command line to enable lombok with ecj: -

java -javaagent:lombok.jar=ECJ -jar ecj.jar -cp lombok.jar -source 1.8 (rest of arguments)

- You may have to add the following VM argument, if you're using an older version of lombok or java: -

-Xbootclasspath/p:lombok.jar

- If you're using a tool based on ecj, adding these VM arguments and adding lombok.jar to the classpath should work. -

Using ecj with Maven

- It is possible to configure maven-compiler-plugin with maven-dependency-plugin and plexus-compiler-eclipse. -

- Before the compile phase, you will have to set your MAVEN_OPTS environment variable to include the javaagent argument. - In the example below, target is your ${project.build.directory}. -

- Use the following commands in sequence to enable lombok with ecj in your Maven build: -

-mvn clean dependency:copy@get-lombok
-set MAVEN_OPTS=-javaagent:target/lombok.jar=ECJ (or your OS's equivalent)
-mvn install
-set MAVEN_OPTS= (or your OS's equivalent)
