Running an executable jar file built from a gradle based project

Question

I have a standalone project which is gradle based. When I do gradle build, the jar is generated under build/libs. How do I run this executable jar from command line? I tried : java -cp build/libs/foo.jar full.package.classname but I get noClassFoundException for the classes that were imported. How do I include dependent jars as part of classpath?

Answer 1

Since question is marked with gradle tag I assume you want to run jar from gradle build. I also assume you use java plugin for your gradle build.

Add next lines in your gradle:

task runFinalJar(type: JavaExec) {    classpath = files('build/libs/foo.jar')    classpath += sourceSets.main.runtimeClasspath    main = full.package.classname } 

You can now include your task to the build process:

build.dependsOn.add("runFinalJar") 

Or just run it form command line:

gradle build runFinalJar 

UPDATE: It is cleaner to use application plugin as Peter suggested
