Analysis of the Build Error

The build error is caused by a duplicate declaration of version in the dependencies of the project. This is a common issue in Maven projects, where the same dependency is declared multiple times with different versions.

Possible Solutions

Remove duplicate dependencies: The first step is to remove the duplicate dependencies from the project. This can be done by removing the duplicate declarations of the dependencies in the project's pom.xml file.
Use a dependency management plugin: Another solution is to use a dependency management plugin, such as the Maven Dependency Plugin, to manage the dependencies of the project. This plugin can help to identify and remove duplicate dependencies.
Use a build tool with better dependency management: If the issue persists, it may be worth considering using a build tool with better dependency management, such as Gradle.

Conclusion

In conclusion, the Maven 4 test results for the kylin repository with Maven version 4.0.0-rc-3 failed due to a duplicate declaration of version in the dependencies of the project. The possible solutions to this issue include removing the duplicate dependencies, using a dependency management plugin, or using a build tool with better dependency management.

Future Work

Future work includes:

Improving the dependency management: Improving the dependency management of the project to prevent duplicate declarations of version.
Using a dependency management plugin: Using a dependency management plugin to manage the dependencies of the project.
Using a build tool with better dependency management: Considering using a build tool with better dependency management, such as Gradle.
