How to solve the issue of idea’s automatic compilation settings not taking effect?

The reason why the automatic compilation setting in IDEA is not effective may be due to the following reasons:

  1. Check if the compilation settings in IDEA are correctly configured. In the IDEA settings, open “Build, Execution, Deployment” > “Compiler” and ensure the “Build Project Automatically” option is checked.
  2. Check if the project’s compile settings are configured correctly. In the project’s settings, open the “File” > “Project Structure” option, choose “Modules” in the left panel, and make sure that the “Make project automatically” option is checked.
  3. Check for errors in the source code of the project. If there are errors in the code, IDEA may stop automatic compilation. Check the bottom status bar of IDEA for error notifications, fix the errors, and recompile.
  4. Check the log output of IDEA. In the installation directory of IDEA, locate the log folder and see if there are any relevant error or warning messages. Troubleshoot and resolve the issue based on the log content.
  5. Check if any other plugins or tools are interfering with the automatic compilation. Disable or uninstall any plugins or tools that may be conflicting with IDEA, then restart IDEA to see if the issue is resolved.

If the above methods are unsuccessful in resolving the issue, you can try the following measures:

  1. Clear the cache of IDEA. Locate the system folder in the installation directory of IDEA, delete the caches folder, and restart IDEA.
  2. Update the version of IDEA. Sometimes, older versions of IDEA may have some known issues, updating to the latest version may help resolve them.
  3. Create a new project. If the above methods don’t work, try creating a new project and importing the existing code into it.

If the issue persists, it is recommended to consult IDEA’s official support or ask in relevant developer community for more detailed help and solutions.
