I downloaded the latest and several older versions of Forge mdk, but when running Gradle each version returns an error:

Caused by: java.util.zip.ZipException: zip END header not found

Event log:

You have a broken jar file somewhere in your gradle cache.

The simplest solution is to delete C:/Users/user/.gradle/caches/forge_gradle. This will require you to re-import any Forge projects though.

To avoid this issue, do not interrupt any of the forge gradle tasks.

there is no folder cache/ or anything like that in the .gradle/.

Before this question I have tried many times to delete and re-download mdk, but this error still appears.

Read again which folder I told you to delete. It is not in your project folder.
