Solving the Mystery: TeamCity Kotlin DSL Builds Not Triggering Automatically, Pending Changes are Detected

Are you tired of staring at your TeamCity dashboard, wondering why your Kotlin DSL builds aren’t triggering automatically, despite having pending changes detected? You’re not alone! In this article, we’ll dive into the possible reasons behind this issue and provide you with step-by-step instructions to resolve it.

The Mysterious Case of Non-Triggering Builds

Before we begin, let’s set the scene: you’ve configured your TeamCity project to use Kotlin DSL, and everything seems to be in order. You’ve written your build scripts, committed the changes, and pushed them to your VCS. But, to your surprise, the builds aren’t triggering automatically. You’ve checked the pending changes, and they’re indeed detected, but the builds remain stubbornly still. What’s going on?

Possible Reasons Behind the Issue

There are several reasons why your Kotlin DSL builds might not be triggering automatically. Let’s explore some of the most common culprits:

• Incorrect VCS Trigger Configuration: Perhaps the VCS trigger configuration is not set up correctly, preventing the build from triggering automatically.
• Kotlin DSL Syntax Errors: A syntax error in your Kotlin DSL script can prevent the build from triggering. Even a small mistake can cause the entire build process to fail.
• Build Configuration Issues: Issues with the build configuration, such as incorrect dependencies or misplaced settings, can prevent the build from triggering.
• VCS Connection Problems: Connection issues with your Version Control System (VCS) can prevent TeamCity from detecting changes and triggering the build.
• Agent Configuration Issues: Misconfigured agents can prevent the build from triggering. Make sure the agent is correctly configured and has the necessary permissions.

Troubleshooting Steps

Now that we’ve identified the possible reasons behind the issue, let’s walk through the troubleshooting steps to resolve it:

Step 1: Verify VCS Trigger Configuration

First, ensure that the VCS trigger configuration is set up correctly. Follow these steps:

1. Go to your TeamCity project and navigate to the “Triggers” page.
2. Click on the “VCS Trigger” and select “Edit”.
3. Verify that the “Trigger on changes” option is enabled.
4. Check the “VCS root” and “Branch” settings to ensure they match your repository and branch.
5. Save the changes and try triggering the build again.

Step 2: Inspect Kotlin DSL Script for Syntax Errors

Next, inspect your Kotlin DSL script for any syntax errors. Follow these steps:

  
    // Example Kotlin DSL script
    import jetbrains.buildServer.configs.kotlin.v2019_2.*

    project {
      buildType("MyBuild") {
        // ...
      }
    }
  

Use the built-in syntax checker in your Kotlin IDE or text editor to identify any syntax errors. Fix the errors and try triggering the build again.

Step 3: Review Build Configuration

Review your build configuration to ensure that everything is correctly set up. Follow these steps:

1. Go to your TeamCity project and navigate to the “Build Configuration” page.
2. Check the build agent requirements, dependencies, and settings to ensure they’re correct.
3. Verify that the “Artifacts” and “Build Steps” are correctly configured.
4. Save the changes and try triggering the build again.

Step 4: Check VCS Connection

Ensure that the VCS connection is working correctly. Follow these steps:

1. Go to your TeamCity project and navigate to the “Version Control Settings” page.
2. Click on the “Test Connection” button to verify the connection to your VCS.
3. If the connection fails, check your VCS credentials and repository URL.
4. Save the changes and try triggering the build again.

Step 5: Verify Agent Configuration

Finally, verify that the agent configuration is correct. Follow these steps:

1. Go to your TeamCity project and navigate to the “Agents” page.
2. Click on the agent responsible for running your build and select “Edit”.
3. Verify that the agent has the necessary permissions and is correctly configured.
4. Save the changes and try triggering the build again.

Additional Tips and Tricks

To ensure that your Kotlin DSL builds trigger automatically, follow these additional tips and tricks:

• Use the TeamCity Debug Mode: Enable the debug mode to get more detailed logs and identify issues faster.
• Monitor the TeamCity Logs: Regularly check the TeamCity logs to identify any errors or issues.
• Test Your Build Script Locally: Test your Kotlin DSL script locally using the TeamCity CLI to ensure it’s working correctly.
• Keep Your Kotlin DSL Script Up-to-Date: Regularly update your Kotlin DSL script to the latest version to ensure compatibility with the latest TeamCity features.

Conclusion

By following the troubleshooting steps and tips outlined in this article, you should be able to resolve the issue of your Kotlin DSL builds not triggering automatically, despite pending changes being detected. Remember to stay vigilant, regularly monitor your build logs, and test your build scripts locally to ensure that your builds are working seamlessly.
