How to solve the problem of running a multi-module project in IDEA without compiling it.

If your multi-module project does not require compilation at runtime, you can try the following solutions:

1. Manual compilation: Compile the required modules using command line or IDE compilation options, then run the project. This ensures that each module is compiled and can run correctly.
2. Set up automatic compilation: Configure automatic compilation in the project’s build tool (such as Maven or Gradle) so that relevant modules are compiled automatically every time the project is run.
3. Check dependencies: Make sure the dependencies between modules in the project are set up correctly, and that each module can find the modules it depends on. Incorrect dependencies can result in certain modules not being able to find the necessary classes or resource files at runtime.
4. Check build configuration: Verify that the project’s build configuration file (such as pom.xml or build.gradle) is properly configured with module paths, dependencies, compilation options, and other relevant information.
5. Check the operating environment: Ensure that the operating environment on which the project depends (such as JDK version, operating system, etc.) is consistent with the project configuration. Different operating environments may cause modules to not run correctly.

If the above methods still cannot solve the problem, it may be necessary to provide more detailed information for further troubleshooting. You can give a more detailed description of the issue so that we can offer more specific solutions.
