This project shows the usage of Gradle plugins to pre-process Java comments and generate multi-release jar files.

After ./gralew build it creates hierarchy structure of pre-processed Java files in build/jcp and the duplicated files are removed.

To build another directory with a different Java version, add another task task compileWithJavaX() with appropriate direction name def java_dir = 'build/jcp/javaX and define vars = [currentJava: 'X']
