I am using IntelliJ IDEA for programming with Gradle on Linux. The problem is, IntelliJ (for some reason) could not detect my Gradle I downloaded myself (version 7.4), so it tried to download one itself (version 7.1) and I couln't stop it. I tried tweaking around a bit and in the end IntelliJ decided it needed one more version, the one it downloaded earlier wasn't enough, so it downloaded version 7.2. After a while I managed to command IntelliJ to use the Gradle I downloaded, but now I am left with two Gradles I don't want to use (versions 7.1 and 7.2). How can I delete them?
Also, IntelliJ downloaded a JDK when I already had one (same story), and it just occupies space. Is there any way to delete it as well?
I can't find any files for neither of them.
Normally IntelliJ installed JDK is inside IntelliJ installation folder in a subfolder named jbr. Gradle will be in plugins subfolder. If you want to remove them, delete the folders.
To find JDKs location go to File | Project Structure | SDKs | select downloaded JDK | JDK home path. Open the mentioned path is OS file explorer and delete the folder.
Regarding the Gradle issue. For now, there is no way to disable gradle wrapper generation by default. Feel free to vote/follow https://youtrack.jetbrains.com/issue/IDEA-215792 . Downloaded distributions can be removed from ~/.gradle/wrapper/dists.
