Failed to load main-class manifest Attribute from… , this is due to the program is not set up to run the entry program.

Right-click on your JAR file, select Open mode — Winrar — to open the Meta-INF folder, and double-click on the MANIFEst.MF file inside. When you open it, you will see that there is only manifest-Version: 1.0 and no main-class: XXX configuration.
