You need to fix build errors in a Java codebase.
The repository is located in /home/travis/build/failed/<repo>/<id>.
Step 1: Analyze the repository to identify the errors causing the build to fail.
Identify if the errors are within the code or build configuration.
Write your analysis and plan in /home/travis/build/failed/failed_reasons.txt.
This file is for you to use in the next step.
Step 2: Use your notes written in /home/travis/build/failed/failed_reasons.txt
to fix the errors.
First, write the changes you proposed in diff files,
Write your changes in files with path/home/travis/build/failed/<repo>/<id>/patch_{i}.diff.
Please write them in standard diff format that is used by git and GNU diffutils.
Step 3: Apply your changes (your diff files) to the repository to fix the build errors.
