Type Configuration cannot be resolved to a type

This error message typically occurs in a Java program when the Java compiler is unable to find the class or interface called "Configuration" in the classpath. This could be due to a missing import statement, an incorrect or misspelled package name, or a missing library or dependency.

To resolve this error, you should first check that you have imported the correct package where the Configuration class is located. If you are using a third-party library, make sure that you have added the library to your project's build path or dependencies.

Also, check if there are any spelling mistakes in the class or package names. Ensure that the class name is exactly the same as in the source code.

If the issue persists, try to clean and rebuild your project. This will help refresh the build path and resolve any issues.

If none of the above steps work, you may need to consult the Java documentation, or seek help from a Java developer.
