"Cannot mount Rom" when runin with running with IntelliJ

[JakobDev]

If I run CC-Tweaked with IntelliJ, I always get this Error: I setup the Mod with this Commands:

./gradlew --stacktrace setupDecompWorkspace --refresh-dependencies
./gradlew --stacktrace cleanIdea idea

Can you upload your run configuration and see if there's anything in the logs? I've never come across this issue, so I suspect it's an issue with your setup.

Here is the log

btw: The Error message is a liitle bit broken on Pocket Computers:

Well, these are somewhat concerning. A couple of things to try:

• Does it work if you use ./gradlew runClient?
• Can you take a screenshot of your run configuration?

[JakobDev]

./gradlew runClient works!

Here's the run configuration:

[JakobDev]

If I load a World that I created in a IntelliJ Instance with a gradlew runClient, I get this Error:

[SquidDev]

Here's the run configuration:

On the "Use classpath of module" section, see if you can select cc-tweaked-1.12.2-main instead. If that doesn't work, then I'm at a loss.

If I load a World that I created in a IntelliJ Instance with a gradlew runClient, I get this Error:

Yeah, ForgeGradle/IntelliJ integration is a little broken so MCMultipart + Charset get injected into the wrong scope. It's OK to hit yes.

[JakobDev]

There is no cc-tweaked-1.12.2-main. There is only cc-tweaked-1.12.2.

[SquidDev]

Ahh, probably because you ran the idea task instead of importing directly. Really not sure what's going on then.

[JakobDev]

This two commands works perfect with the old CC. What commands do you suggest instead to make the code ready for IntelliJ?

[SquidDev]

Curious - nothing should have changed which'd cause file mounts to suddenly stop working. I Just use IntelliJ's built-in Gradle importing instead.

[JakobDev]

How do I run the mod, if I use the Gradle importer? "Minecraft Client" is not in the list.

[SquidDev]

You can use ./gradlew genIntellijRuns, or just create a new task like your screenshot above. See also the MinecraftForge docs.

[JakobDev]

That worked for me! Thanks!
