I am currently experimenting with Maven in Eclipse (m2e-Plugin) and tried to build and run the Hello World example project. However, when launching the generated jar, nothing happens. I checked the MANIFEST.MF and noticed that the Main-Class attribute was missing. After adding the attribute, the jar could be launched.
Why does Maven not add this attribute?
Have a look at this link: https://maven.apache.org/shared/maven-archiver/examples/classpath.html#aAdd You can find there how to configure your maven project to run specific class. You have to add maven-jar-plugin configuration with mainClass defined.
