Build failed.

Description: 

This error occurs when your build fails while running Selenium automation with TestNG. The most common cause of this error is an incorrect TestNG configuration file. If the TestNG configuration file does not adhere to the annotations, attributes, and values used in the project, the build may fail.

Debugs:

Debug 1 Check your TestNG configuration file: 

Ensure that the TestNG configuration file is correct and includes all the necessary annotations, attributes, and values used in the project. Make sure that the file path in the build.gradle file is pointing to the correct TestNG file.

Debug 2 Check for syntax errors: 

Make sure there are no syntax errors in your TestNG configuration file or in your build.gradle file. Syntax errors can cause the build to fail.

Debug 3 Check for missing dependencies: 

Make sure that all necessary dependencies are included in the build.gradle file. Missing dependencies can cause the build to fail.

Extra Information: 
Gradle is a build tool used to automate building, testing, and deploying software. It is important to ensure that all necessary dependencies are included in the build.gradle file to prevent build failures.
