How to send classes of some (not all) libraries to binary in Gradle?

Question

Java

Initially, I needed the binary of my project to contain, in addition to my classes, also the classes of some libraries.
Found this solution for Gradle:

jar {
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}

But this does not suit me, because. this line sends the classes of absolutely all the libraries that I use to the binary and it turns out to be a garbage dump.
So, to the heart of the matter: how do I send the classes of only one library to my binary? For example, json-simple library classes (com.googlecode.json-simple', name: 'json-simple', version: '1.1.1)

Answer 1

Maybe so?

jar {
  from {
    configurations.compile.resolvedConfiguration.resolvedArtifacts.findAll {
      it.moduleVersion.id.with { it.group == 'com.googlecode.json-simple' && it.name == 'json-simple' }
    } collect {
      it.file.with { it.isDirectory() ? it : zipTree(it) }
    }
  }
}
