mvn cannot find symbol

When Maven cannot find a symbol, it means that a required class or method is missing or not available in the classpath. This error can occur due to various reasons such as:

1. Missing dependency: If a required dependency is not declared in the POM file or is not available in the local or remote repository, Maven cannot find the symbol.

2. Incorrect package name: If the package name of the class is incorrect or does not match the directory structure, Maven cannot find the symbol.

3. Compilation error: If there is a compilation error in the code, Maven cannot find the symbol.

To resolve this error, you can try the following steps:

1. Check the POM file for missing dependencies and add them if necessary.

2. Check the package name and directory structure of the class.

3. Check the code for compilation errors and fix them.

4. Clean and rebuild the project using the command "mvn clean install".

5. If the symbol is provided by a third-party library, make sure that the library is added to the classpath.

6. If the error persists, try running Maven in debug mode (-X option) to get more information about the error.
