Can't execute jar- file: “no main manifest attribute”

Question

I have installed an application, when I try to run it (it\'s an executable jar) nothing happens. When I run it from the commandline with:

java -jar \

Answer 1

For maven, this is what solved it (for me, for a Veetle codebase on GitHub):

  
    org.apache.maven.plugins
    maven-shade-plugin
    2.0
    
      
        package
        
          shade
        
        
          
            
              org.lazydevs.veetle.api.VeetleAPI
            
          
        
      
    
  
 

Cheers...
