I'm trying to build Energy Control from source, but I've come across several issues.

The issue(s)

1. The gradle wrapper is not redistributed with the source, so I had to download it myself. Later, a couple of dependency errors showed up, saying that ic2, techreborn, and reborncore couldn't be resolved. I went on and fixed the issues by adding Player's and ModMuss' maven repositories.
2. A lot of classes are missing from the source. However, they are present in the release jar (EnergyControl-1.12.2-0.1.12.jar). Full error log: https://pastebin.com/r3jZttQh

Expected behavior

Energy Control's source works out of the box, and can be built by simply running gradlew build.

Additional context

I will submit a PR to fix the first issue, but I can't solve the other one since the said classes were never published.
