The project cannot be built until build path errors are resolved

This error message indicates that there are issues with the build path of your project. Here are some steps to resolve this error:

1. Check if any of the required libraries or dependencies are missing from the build path. You can add them by navigating to the project properties and selecting the build path option.

2. Ensure that the correct JDK version is selected in the build path. You can do this by going to the Java Build Path option and selecting the Libraries tab.

3. If you recently updated any plugins or libraries, make sure that they are compatible with your project's current version.

4. Remove any duplicate libraries or dependencies from the build path.

5. If none of the above steps works, try cleaning and rebuilding the project.

Hopefully, one of these steps will help you resolve the build path errors and successfully build your project.
