I do have a windows 11 machine where i downloaded, installed, registered a gitlabrunner vers. 17+, runner is online visible in the gitlab instance.
I have maven installed and under path, java JDK 21, etc. on the windows 11 machine (all working fine).
When I trigger a gitlab run having a maven build from yaml file, even simplest command i.e. “maven clean install”, gitlab job runs, maven build appears as successful in the gitlab logs, but in the end gitlab job remains hanging until timeout (timeout is set for 30 min).
If i trigger manually the maven build in the terminal everything works fine on the windows machine, build is successful and command finishes gracefully.
If i enter an echo command in the yaml file, and execute the gitlab job, it works fine, and the windows based gitlab runner ends gracefully (as expected).
Not sure what to verify or how to debug this, basically my goal is to be able to execute a maven command from the gitlab yaml file and the gitlab runner to run it succesfully without hanging when it finishes.
Incorrect Maven Version: Ensure that the Maven version installed on your Windows 11 machine is compatible with your GitLab runner and the project requirements. Check the Maven version in your GitLab runner’s configuration and compare it to the version you have installed.
Missing Dependencies: Verify that all necessary dependencies for your Maven project are present and correctly configured. Missing dependencies can cause the build to hang.
Incorrect Build Configuration: Review your Maven build configuration (e.g., pom.xml ) for any errors or inconsistencies. Pay attention to plugin configurations, dependencies, and build lifecycle phases.
2. GitLab Runner Configuration Issues:
Incorrect Runner Configuration: Double-check your GitLab runner’s configuration file (e.g., config.toml ) for any errors or incorrect settings. Ensure that the runner is correctly configured to execute Maven builds and that the Maven executable path is specified correctly.
Insufficient Resources: If your GitLab runner is running on a resource-constrained machine, it might not have enough memory or CPU to handle Maven builds. Try increasing the runner’s resource limits or allocating more resources to the machine.
Network Issues: If your GitLab runner is unable to communicate with Maven repositories or other external services, the build might hang. Check your network connectivity and firewall settings.
3. Project-Specific Issues:
Build Complexity: If your project has a complex build process with many dependencies or custom plugins, it might take longer to complete. Increase the GitLab job’s timeout if necessary.
Maven Plugin Issues: Some Maven plugins might have known issues or incompatibilities that can cause builds to hang. Check the plugin’s documentation or community forums for any reported problems.
Troubleshooting Steps:
Check Maven Version and Configuration:
Verify that the Maven version installed on your Windows 11 machine matches the version specified in your GitLab runner’s configuration.
Inspect your pom.xml file for any errors or inconsistencies.
Review GitLab Runner Configuration:
Ensure that the runner is configured to execute Maven builds and that the Maven executable path is correct.
Check for any network connectivity or firewall issues.
Test with a Simple Project:
Create a simple Maven project with minimal dependencies and try running a build through GitLab. If it works, the issue might be specific to your project’s build configuration.
Increase Timeout:
If your project has a complex build process, increase the GitLab job’s timeout to give it more time to complete.
Check Maven Plugin Documentation:
If you’re using custom Maven plugins, check their documentation for any known issues or compatibility problems.
Enable Debug Logging:
Enable debug logging in your GitLab runner’s configuration to get more detailed information about the build process. This can help identify the root cause of the issue.
By following these steps and carefully analyzing the logs and error messages, you should be able to identify and resolve the issue causing your GitLab runner to hang during Maven builds.
