picocli-4.6.0.jar requires groovy for OSGi but not for Maven

[Fiouz]

Since 4.6.0, the META-INF/MANIFEST.MF file of the main artifact contains the following line:

Import-Package: groovy.lang

This does not seem correct as there is a dedicated artifact for Groovy support, and, since it does not match the pom.xml definition, it confuses consumers that rely on the POM definition to construct their OSGi repository:

org.osgi.framework.BundleException: Unable to resolve picocli [3](R 3.0): missing requirement [picocli [3](R 3.0)] osgi.wiring.package; (osgi.wiring.package=groovy.lang) Unresolved requirements: [[picocli [3](R 3.0)] osgi.wiring.package; (osgi.wiring.package=groovy.lang)]
