1 year ago It seems that you are encountering an error while running the Bazel build command for the helloworld target in the com/google/j2cl/samples/helloworld package. The error message suggests that there are unused native files causing the build failure.
Here are a few suggestions to troubleshoot the issue:
Check the build configuration: Ensure that you have the correct dependencies and build settings configured for the J2CL project. Make sure that all required dependencies are correctly specified in the BUILD files and that your Bazel workspace is set up properly.
Verify the J2CL version: Ensure that you are using a compatible version of the J2CL transpiler. Check if there are any specific version requirements or compatibility issues mentioned in the project's documentation or release notes. You might need to update or adjust the J2CL version accordingly.
Clean and rebuild: Try cleaning the Bazel build cache and performing a clean build. Run bazel clean --expunge to remove any cached build artifacts and then try building again using the bazel build command.
Check for unused native files: The error message indicates that there are unused native files causing the build failure. Review the J2CL project's configuration and make sure that the native files are correctly included or excluded as needed. You might need to update the build configuration to address this issue.
Enable verbose output: If the issue persists, you can use the --verbose_failures flag with the bazel build command to get more detailed information about the failed build steps. This can help you identify the specific cause of the failure.
If none of these suggestions resolve the issue, I recommend consulting the J2CL project's documentation, issue tracker, or community forums for further assistance. They may have specific recommendations or workarounds for the problem you are facing.
