Jar in Jar

[sick pendant]

Hello, fellow coders!
I've been programming a library, and need to add it as a dependency in my Gradle project. I simply built the library jar, then drag-and-dropped it into a directory in my project called 'lib'. Then, in my build.gradle dependencies, I added :

implementation fileTree('dir': 'lib', include: '*.jar')

This work in IntelliJ before compilation, however when I run the resulting jar, it cannot find any of the classes in the library. The problem is obviously that the library is not being packaged in the jar, but I can't seem to be able to fix that. I've tried adding this to the 'jar' task :

from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it)
            exclude("module-info.class") }
    }

But that just gives me this error :

Circular dependency between the following tasks:
:jar
\--- :jar (*)

Please note : the Gradle project is a Fabric mod, but I don't think that should affect anything.

Any help would be very much appreciated, thanks!

the library isn’t in the actual jarfile when distributed

i have a nice snippet for including dependencies like that somewhere, give me a second

OK thx

Completely forgot about this post, use this:

configurations {
  jarInJar
}
dependencies {
  // ...
  jarInJar implementation("what:ever:1.2.3")
}

jar {
  // ...

  from {
    configurations.jarInJar.collect { it.isDirectory() ? it : zipTree(it) }
  }
  duplicatesStrategy(DuplicatesStrategy.EXCLUDE)
}

Thanks! And don't worry, that's fine.
