Could not find or load main class with a Jar File

Question

I\'m trying to load a jar using

@echo off
java -jar Test.jar
pause

With the manifest of

Manifest-Version: 1.0
Main-Class:          


        

Answer 1

I had this error because I extracted JAR files from libraries to the target JAR by IntellijIDEA. When I choose another option "copy to the output directory...", it solved the problem. Hope this helps you
