How can I debug failures in Travis CI?

I'm facing some failures in my Travis CI builds. How can I debug them?

First, check the build logs for any error messages. They often provide clues about what went wrong.

I see some errors related to missing dependencies. What should I do?

Make sure all required dependencies are listed in your configuration file. You might also want to clear the cache.

How do I clear the cache in Travis CI?

You can clear the cache by adding cache: false in your .travis.yml file or by using the Travis CI web interface.

Thanks! Is there a way to run builds with different configurations?

Yes, you can use matrix builds in your .travis.yml to test multiple configurations simultaneously.
