Im trying to build this mod for playing since the latest release is ~500 commits behind.
Im not a java guy though, so this is new ground for me and im running into all kinds of issues.

first of: setup.sh fails because gradlew doesnt work.
I've been able to work around this by installing gradle myself and changing setup.sh

then deploy shows a lot of errors and there doesn't seem to be a proper build in ./build.

also build_luaj.sh fails for me. al though I might not even need to run this.

There's two ways:

• Don't! https://cc.crzd.me/ has pre-built versions of most branches, so if you don't want to make any modifications you can just use that.
• Run ./gradlew setupDecompWorkspace to setup Forge, then run ./deploy.sh to build - the resulting file should be at deploy/ComputerCraft-xxx.jar

It might also be worth having a look at Forge's docs on getting a development environment set up.

thnx for you quick response, ik hit enter on accident and created the issue while I still wanted to type my message.

thnx for the tip! I will go with option one :)
