Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:purge-local-repository (

This error message indicates that the Maven Dependency plugin has failed to execute the "purge-local-repository" goal. This goal is responsible for removing all dependencies from the local repository.

There could be several reasons for this error, including:

1. Incorrect plugin configuration: Check that the plugin configuration in your POM file is correct and up-to-date.

2. Permissions issue: Ensure that you have the necessary permissions to write to the local repository directory.

3. Network issues: If you are using a remote repository, there could be network connectivity issues that are preventing the plugin from downloading the necessary dependencies.

To resolve this issue, you can try the following steps:

1. Clean your local repository by deleting the contents of the .m2/repository directory.

2. Update the plugin version to the latest version.

3. Check your network connectivity to ensure that you can connect to any remote repositories.

4. Check the plugin configuration in your POM file for any errors or inconsistencies.

If none of these steps resolve the issue, you may need to seek additional support or consult the Maven documentation for further troubleshooting steps.
