@yuvalavr24 Same problem. How to resolved ~?

This issue is related with a post java installation step of the action that attempts to write the toolchain.xml file in the settings repository:

  const settingsDirectory =
    core.getInput(constants.INPUT_SETTINGS_PATH) ||
    path.join(os.homedir(), constants.M2_DIR);

The code above defines the settings directory in toolchains.ts of the source code of the action.

After java is installed, unless the overwrite-settings are set to false, the action tries to overwrite the toolchain.xml file created.
Currently, there exists an open issue where for self-hosted runners, this file is not overwritten but information is appended.
I faced same issue and when I debugged the job, I found that my file was huge. I did not check the actual issue in depth since it was +40k long yet I saw a lot of repeated configurations and I expected some malformation of the file.

After the file was deleted, the issue is fixed.

Note that this may happen again at some point because of the previous open issue I mentioned.
This is only a workaround to fix the issue.
