[SOLVED] Mod setup issues: "Could not find mapped snapshot"

[Hamster_Furtif]

EDIT: SOLVED BY DELETING THE  .gradle DIRECTORY AND REFRESHING THE GRADLE PROJECT

 

Hello, I'm trying to set up a mod in 1.15.2 using IntelliJ.

 

To set it up, I've opened the build.gradle file from IntelliJ as a project, then ran the getIntellijRuns  from the gradle pannel, then ran the gradle build command into the terminal.

 

Here is a pastebin of the terminal output:

I believe this is the most relevant part :

* What went wrong:
Could not resolve all files for configuration ':compileClasspath'.

  Required by:
      project :

 

This is what it looks like on the gradle pannel:

 

When I go to File>Project Structure>Libraries, it also tells me that the mapped snapshots lib cannot be found.

 

I've seen a few other forum posts with the same issue, but none of them could help me solve this issue. I've tried (with no success):

-to update my JDK (1.8 to 1.12)

-to edit the mappings version field in the build.gradle file, using the latest MPCBot release

mappings channel: 'snapshot', version: '20200223-1.15.1'

 

I'd be really grateful if someone could help me sort this out.

Try deleting the build folder in your project and refresh gradle

[Hamster_Furtif]

Thanks for your suggestion, but unfortunately this didn't work. The issue remains even when restarting from a clean mdk, but only with forge 1.15.

However I noticed that the directory gradle is looking for does not exists:

C:/Users/HamsterFurtif/.gradle/caches/forge_gradle/bundeled_repo/net/minecraftforge/forge/1.15.2-31.1.0_mapped_snapshot_20200223-1.15.1/

But this one exists:

C:\Users\HamsterFurtif\.gradle\caches\forge_gradle\minecraft_user_repo\net\minecraftforge\forge

and contains the files gradle is looking for.  It is the one that is used by my 1.14 project, but I can see the 1.15 files were downloaded there.

I guess what I need to do is to force gradle to search in there but I have no idea how to do that. I'm also curious as to why it works fine with 1.14 but not 1.15.

Some of the stuff I had written was incorrect

[Hamster_Furtif]

Not sure what the rules are on replying to my post, sorry if I'm breaking any rule.

I've tried using the the "latest" version of the forge 1.15 mdk and it still doesn't work, the jars required are nowhere to be found.

It sounds like you interrupted a mapping download. Try this in Powershell:

Remove-Item -Recurse -Path "$Env:USERPROFILE/.gradle/caches/forge_gradle/maven_downloader/de/oceanlabs/mcp/mcp_snapshot/20200223-1.15.1"

This will delete the cached mapping zip (which is apparently corrupted) and its hash.

[Hamster_Furtif]

The command runs well but doesn't solve the issue. I've tried it a few times. I've also checked the hash code and it matches perfectly.

[Hamster_Furtif]

Bump. I've tried using Eclipse but encountered the same error.

[Stragulus]

The solution forgets to mention that you may still have a gradle daemon running. You *must* stop the daemon first, then delete the caches and try a new build. That explains why you may still be running into issues even after a refresh.

I tried the same thing by deleting the .gradle directory and restarting but i still got the errors.

U may use this link to look at an image to my problem. I am really new to IntelliJ(like i dont even know what gradle is) and i really want to mod but this error is happening and ur edited solution doesnt work for me.

Have you tried in IntelliJ IDEA to do the Invalidate Caches / Restart under the File menu?

Could you also share the build.gradle file content?
