Minor issues encountered with the Java-jar command (MAVEN project) |xx.jar no master manifest or error:invalid or corrupt jarfile Xx.jar

No master list or error:invalid or corrupt jarfile Xx.jar in Xx.jar

　　This problem is encountered because your jar package does not have a portal set for the main class.

　　That is, Main-class:packagename.classname is not defined in the MANIFEST.MF file of the Meta-inf folder(here Main-class: with Packagename.classname A space and a newline character at the end of the line)

　　We can open your export jar with WinRAR (do not unzip), find the Manifest.mf file in the Meta-inf folder, open it with Notepad, add Main-class: Package name. Main class name

But the jar files packaged by the MAVEN project can't be run, even if you're MANIFEST. MF file added Main-class also cannot be resolved

The reason may be that your MAVEN project's pom.xml configuration is too simple or does not specify a package type, because a MAVEN project packaged as a jar file requires some specific environments to be configured!
