Jenkins uses plugins to add features and connect with other tools. Sometimes plugins may not work well together or with Jenkins itself. Checking compatibility helps avoid errors and keeps your automation running smoothly.
When you want to add a new feature to Jenkins using a plugin but need to ensure it works with your Jenkins version.
When upgrading Jenkins and you want to verify that your existing plugins will still function correctly.
When installing multiple plugins that depend on each other and you want to avoid conflicts.
When troubleshooting build failures that might be caused by incompatible plugins.
When planning to remove or update plugins and want to understand the impact on your Jenkins setup.

Key Concept

If you remember nothing else, remember: always verify plugin compatibility with your Jenkins version before installing or upgrading plugins to avoid failures.

Common Mistakes
Installing plugins without checking if they are compatible with the current Jenkins version.
This can cause Jenkins to fail to start or plugins to malfunction.
Use plugin compatibility information from the plugin manager or jenkins-plugin-cli before installation.
Upgrading Jenkins without upgrading plugins accordingly.
Plugins may not work with the new Jenkins version, causing errors.
Upgrade plugins to compatible versions immediately after upgrading Jenkins.
Ignoring plugin dependencies and installing plugins separately.
Missing dependencies can cause plugins to break or Jenkins to behave unpredictably.
Check and install all required dependencies together.
Summary
Use jenkins-plugin-cli or Jenkins UI to list installed plugins and their versions.
Check plugin compatibility information before installing or upgrading plugins.
Upgrade plugins to compatible versions when Jenkins is upgraded.
Always consider plugin dependencies to avoid conflicts.
