run main method using gradle “run” task

Question

I want to run my main method via gradle task

This is how I run via the cmd:

java -cp RTMonitor.jar com.bla.MainRunner first_arg

Answer 1

The easiest is probably to use application plugin. Add apply plugin: 'application' to your build.gradle and set mainClassName = com.bla.MainRunner . To add arguments to your main class modify the run task and edit the args property

run {
  args += 'first_arg'
}

Classpath is taken automatically from main sourceSet, if you want different one, you can edit classpath property of the run task.

If you need more customization, you can define your own task of type JavaExec like this

task myRun(type: JavaExec) {
  classpath sourceSets.main.runtimeClasspath
  main = "com.bla.MainRunner"
  args "arg1", "arg2"
}
