Working with a dependency on a bundle of JAR files

You can have a build.gradle in buildSrc that does the same thing, I believe. Are you having problems with that and do you have a small project to recreate?

Looking at your code snippet, I notice a few things you could improve. Because you’re adding to the main classpath during the execution (vs configuration) phase, you could run into ordering problems.

A more Gradle-idiomatic looking example might look like this:

configurations {
  bundlecfg
}
  task extractJarBundle(type: Copy, dependsOn: configurations.bundlecfg) {
  from { configurations.bundlecfg.collect { zipTree(it) } }
  into "${buildDir}/lib"
}
  dependencies {
  bundlecfg 'group:bundle:someVersion'
  compile fileTree(tasks.extractJarBundle.outputs.files.singleFile) {
     builtBy tasks.extractJarBundle
     include "**/*.jar"
  }
}

This uses the ‘builtBy’ property of the file collections to auto-wire things together (compileJava needs configurations.compile which needs extractJarBundle which needs configurations.bundlecfg).
