When creating a JAR file using Maven, the class files (or rather the package structure) are placed directly in the root of the JAR file. How can I configure Maven (or the maven-jar-plugin) to copy the classes to a "classes" directory instead? For example, the jar file should have the following structure:
- classes
- com
- mycompany
- myapp
- HelloWorld.class
- META-INF
- MANIFEST.MF
The structure of the sources should not be changed (it's the Maven default structure).
Many thanks for any help.
