Fix Gradle | Partially fix jitpack

[KaspianDev]

Not sure what caused gradlew to break but here's what I ran to fix it (tested):

• sed -i -e 's/\r$//' gradlew

For the jitpack, this is the last error left which I don't have to fix currently

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':eco-core:core-plugin:publishLibraryPublicationToMavenLocal'.
> Failed to publish publication 'Library' to repository 'mavenLocal'
   > Invalid publication 'Library': multiple artifacts with the identical extension and classifier ('jar', 'all').

@WillFP Look into it please when you have time.
