Are you tired of watching your Jenkins build hang indefinitely, only to discover that the next command starts without completing the previous one? You’re not alone! This frustrating issue has plagued developers and Jenkins enthusiasts alike, leaving us wondering what went wrong and how to rectify the situation. Fear not, dear reader, for we’re about to dive into the root causes and provide a step-by-step guide to resolving this pesky problem once and for all!
Understanding the Jenkins Devenv Build Process
Before we dive into the solution, it’s essential to understand how Jenkins handles builds using the Devenv command. Devenv is a command-line utility that comes with Visual Studio, allowing you to build, clean, and deploy projects from the command line.
In a Jenkins build, the Devenv command is typically used to compile and build projects. The command is executed in a batch script or as a single command in a Jenkins build step. When the command is executed, Jenkins waits for the command to complete before moving on to the next step in the build process.
The Culprit: Why Your Build Isn’t Finishing
So, why does the build hang indefinitely, and why does the next command start without completing the previous one? There are a few common culprits to blame:
- Devenv command not completing: The Devenv command might not be completing successfully, causing Jenkins to wait indefinitely for the command to finish.
- Background processes: Devenv might be spawning background processes that aren’t being terminated properly, preventing the build from completing.
- Missing dependencies: Your project might be missing essential dependencies, causing the build to fail or hang.
- Incorrect configuration: Your Jenkins configuration might be incorrect, leading to issues with the build process.
Fixing the Issue: Step-by-Step Instructions
Now that we’ve identified the potential causes, let’s dive into the step-by-step guide to resolving this issue:
Step 1: Verify Devenv Command Completion
Check your Devenv command to ensure it’s completing successfully. You can do this by:
- Running the Devenv command manually in a command prompt or terminal.
- Verifying that the command completes successfully and returns an exit code of 0.
Step 2: Identify and Terminate Background Processes
Identify any background processes spawned by Devenv and terminate them to ensure a clean build environment:
taskkill /im devenv.exe /f
taskkill /im msbuild.exe /f
These commands force-terminate any Devenv and MSBuild processes that might be running in the background.
Step 3: Verify Dependency Installation
Ensure all necessary dependencies are installed and configured correctly:
- Verify that Visual Studio and the required SDKs are installed on your Jenkins node.
- Check that the environment variables are set correctly, such as the PATH variable.
Step 4: Configure Jenkins Correctly
Review your Jenkins configuration to ensure it’s correct:
- Verify that the Jenkins node is configured correctly, with the correct environment variables and SDKs installed.
- Check that the build step is configured to use the correct Devenv command and arguments.
Step 5: Add a Timeout to Your Devenv Command
To prevent the build from hanging indefinitely, add a timeout to your Devenv command:
devenv MyProject.sln /build "Release|Any CPU" /timeout:500
This command adds a timeout of 500 seconds (or 8 minutes and 20 seconds) to the Devenv command. Adjust the timeout value according to your build requirements.
Step 6: Monitor Your Build Logs
Keep a close eye on your build logs to identify any issues or errors:
- Monitor the Jenkins build log for any errors or warnings.
- Check the build log for any signs of the Devenv command hanging or failing.
Additional Tips and Tricks
To further optimize your Jenkins build process, consider the following tips and tricks:
- Use a clean build environment: Ensure your Jenkins node has a clean build environment, free from any residual files or processes.
- Split your build into smaller chunks: Divide your build into smaller, more manageable chunks to reduce the likelihood of hangs and timeouts.
- Use a retry mechanism: Implement a retry mechanism to rerun the build step if it fails or times out.
Conclusion
There you have it, folks! By following these steps and understanding the underlying causes of the issue, you should be able to resolve the pesky problem of Jenkins Devenv builds not finishing because the next command starts. Remember to stay vigilant, monitor your build logs, and keep your build environment clean and optimized.

Frequently Asked Question
Get the scoop on how to tackle the pesky issue of Jenkins devenv build not finishing because the next command starts!
Why does my Jenkins devenv build not finish because the next command starts?
This issue often occurs when the devenv command doesn’t return control to Jenkins, causing the build to hang indefinitely. It’s like a pipeline party that never ends! To resolve this, try adding the `/wait` option to your devenv command, which tells it to wait for the build to complete before exiting.
How do I add the /wait option to my devenv command in Jenkins?
Easy peasy! Simply append the `/wait` option to your devenv command in the Jenkins build step, like this: `devenv /wait /build Release`. This tells devenv to wait for the build to complete before handing control back to Jenkins.
What if I’m using a batch script to call devenv in Jenkins?
No worries! In that case, you can add the `call` command before the devenv command in your batch script. This ensures that the batch script waits for devenv to complete before proceeding, like this: `call devenv /wait /build Release`. Problem solved!
Can I use this solution for other types of builds in Jenkins, not just devenv?
While the `/wait` option is specific to devenv, the concept of ensuring that commands wait for each other to complete is applicable to other build types in Jenkins. Just investigate the specific options available for your build tool and adjust accordingly. For example, some build tools might require the `&&` operator to chain commands.
What if I’m still having issues with my Jenkins build after trying these solutions?
Don’t panic! If you’re still stuck, try enabling verbose logging in Jenkins to get more detailed output from your build. This can help you identify the root cause of the issue. You can also consult the Jenkins documentation, online forums, or seek help from a colleague who’s more familiar with Jenkins build configurations.
