Maven: missing net.sf.json-lib

How to execute maven plugin execution directly from command line?

December 26, 2022 by Tarik

This functionality has been implemented as MNG-5768, and is available in Maven 3.3.1. The change will: extend direct plugin invocation syntax to allow optional @execution-id parameter, e.g., org.apache.maven.plugins:maven-remote-resources-plugin:1.0:process@executionId. So, in your case: mvn antrun:run uses the default-cli execution ID, and: mvn antrun:run@my-execution uses the execution configured in your pom.
