When I build a JAR library using Maven 2 (version 2.0.9 or 2.2.1), the pom.xml of the library is copied in the META-INF/maven/[g
2.0.9
2.2.1
pom.xml
META-INF/maven/[g
Use https://www.mojohaus.org/flatten-maven-plugin/
It will set updatePomFile true by default.
Its not what you asked for, but its what you want.
