Main-Class: yourpacket.yourmainclass (for exmaple ) Open MANIFEST.MF file from META-INF\MANIFEST.MFĬopy the real MANIFEST.MF that already generate in your project by MAVEN.The MAVEN problem is that its try to include the first MANIFEST.MF file from first library from dependencies instead of THE OUR OWN MANIFEST.MF WHEN YOU USE ARTIFACTS!. Note that this is only the plugin definition, not the full pom.xml: jar įor Maven, something like the following snippet should do the trick.
