Git-commit-id-maven-plugin: Cannot save config file 'FileBasedConfig[H:\.config\jgit\config]'

[bernardpaulus]

Describe the bug

During maven build, we observe the following error message from git-commit-id-maven-plugin 4.0.5:

Cannot save config file 'FileBasedConfig[H:\.config\jgit\config]'

The H: drive is a network drive where our home dir is set

Steps to Reproduce

• mvn -version

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: C:\Users\<redacted>\tools\maven\3.6.3
Java version: 1.8.0_201, vendor: Oracle Corporation, runtime: C:\Program Files\Java\JDK8\jre
Default locale: en_GB, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

• Plugin config:

      <plugin>
        <groupId>pl.project13.maven</groupId>
        <artifactId>git-commit-id-plugin</artifactId>
        <version>4.0.5</version>
        <configuration>
          <failOnNoGitDirectory>false</failOnNoGitDirectory>
          <offline>true</offline>
        </configuration>
      </plugin>

• no public build
• Observed error:

    Cannot save config file 'FileBasedConfig[H:\.config\jgit\config]'

This error doesn not prevents the maven build from being executed with success. However, intelliJ Community 2019.3 spots it as an error:

Expected behavior

• no error message printed

Hello,
thank you for reporting this issue here! When I read the linked ticket (https://bugs.eclipse.org/bugs/show_bug.cgi?id=566170) correctly this should be fixed whenever we update the jgit-library to version 5.9?!?

For the time being you could potentially switch to the native git binary via <useNativeGit>true</useNativeGit> which would help avoid that issue since it doesn't rely on jgit.

Ah I just realized that this is essentially a duplicate of https://github.com/git-commit-id/git-commit-id-maven-plugin/issues/518. At least it's the same issue. Perhaps a different context....not sure if I should keep both issues open, but I guess it doesn't hurt either.

[bernardpaulus]

The difference with #518 is that there the build fails while in this case it does not

thanks for the useNativeGit tip!

[TheSnoozer]

thanks for pointing out that difference!
Could you perhaps also confirm which version you are using?
If you are on 4.0.5 this should already include jgit 5.12.0.202106070339-r (see https://github.com/git-commit-id/git-commit-id-maven-plugin/blob/v4.0.5/core/pom.xml#L20). Based on the closed bug report (https://bugs.eclipse.org/bugs/show_bug.cgi?id=566170) this should have been fixed in 5.9.X....hence this would make me suspect that it is not fixed properly and would deserve a new ticket, or to have the old to be reopened.

Same problem here with 4.9.10:

[INFO] --- git-commit-id-plugin:4.9.10:revision (default) ...
[ERROR] Cannot save config file 'FileBasedConfig[H:\.config\jgit\config]'
java.io.IOException: Creating directories for H:\.config\jgit failed

<useNativeGit>false</useNativeGit>

doesn't make a difference

[TheSnoozer]

Sorry it should have been <useNativeGit>true</useNativeGit> I have updated my initial comment.
