Unable to publish on Jitpack: Execution failed for task ':install'

Question

Well, I'm since about 4 hours trying to publish my project on JitPack, but I always get the same error:

Execution failed for task ':install'.

I searched a lot, but nothing was found about it.

Log: https://jitpack.io/com/github/NathanPB/DogoAPI/master-63f1267b6d-1/build.log

Repo: https://github.com/NathanPB/DogoAPI

What am I doing wrong?

Answer 1

Looking on the log, luX told me that the jar task was skipped:

:jar SKIPPED

Then, I modified my build.gradle from

jar {
    manifest {
        attributes 'Main-Class': 'cf.dogo.api.DogoAPIKt'
    }
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } 
    }
}

To

jar {
    enabled = true
    manifest {
        attributes 'Main-Class': 'cf.dogo.api.DogoAPIKt'
    }
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } 
    }
}

Adding enabled = true for jar task. Everything worked very well after that.
