Exactly what the title says, whenever I try to build it manually with .\gradlew build in powershell it doesn't work. If anybody else could help, it would be much appreciated. If I should move this elsewhere, please let me know.

Otherwise, it says 0% EXECUTING
:compileJava > Resolve dependencies of :compileClasspath

that 0% executing is normal and isn't any sort of error, it just means its loading

how long should it stay like that for? I left it for 10 minutes and it didn't change once, the time just kept ticking up

depends on how good your internet is - it's probably downloading all the gradle dependencies

my internet is pretty good, but ill start it up again and go binge watch something, at what point should i come back and ask?

I mean, at a maximum, how long should it take?

maybe at max 30 minutes

when i started it up this time, it took like 2 minutes and did this

cant help ya anymore, i dont really know 1.16 modding

thanks for trying. If anybody else who sees this can help, please do.

Are you sure to have executed .\gradlew genEclipseRuns and .\gradlew eclipse (to be able to download the libraries 1.16

Sorry i took so long, the first 2 ran successfully but the actual build failed

Task :compileJava FAILED

FAILURE: Build failed with an exception.

project :

It is trying to get the dependencies and can't retrieve them from online or local, have you tested the links it is attempting? Could also try using the source in my fork, I know for sure that builds as it is.

Ultimately, if you plan on pursuing mod dev/build related activities I would highly recommend using IntelliJ Idea, it makes the whole process a LOT easier.
