Question

It there any way to avoid duplication in configuration between two similar tasks of the same type?

For example, I\'d like to create a debugSomething task, w

Answer 1

This can be solved using plain Groovy:

task runSomething(dependsOn: jar, type: JavaExec, group: "Run") {
}

task debugSomething(dependsOn: jar, type: JavaExec, group: "Run") {
    jvmArgs "-agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=y"
}

[runSomething, debugSomething].each { task ->
    task.main = "com.some.Main"
    task.classpath = sourceSets.main.runtimeClasspath
    task.jvmArgs "-Xmx1024m", "-XX:MaxPermSize=128m"
}

Even though debugSomething.jvmArgs is invoked twice, all three arguments are supplied to the JVM.

Single arguments can be set using Groovy's Spread operator:

[runSomething, debugSomething]*.main = "com.some.Main"
