Do you face this issue ?

Error extracting plugin descriptor: 'Goal: * already exists in the plugin descriptor for prefix: *

[ERROR] Existing implementation is: *.*Mojo

[ERROR] Conflicting implementation is: *.*Mojo'

[ERROR] -> [Help 1]

Solution :

You may encounter this error when changing a build -> directory on pom.xml

By default build directory will be target directory. If you face this issue, delete the target directory as well as newly specified build directory and install again.

Happy Coding :)
