Building a runnable jar with Maven 2

Question

I\'m relatively new to the Maven mantra, but I\'m trying to build a command-line runnable jar with Maven. I\'ve setup my dependencies, but when I run mvn install

Answer 1

The easiest way to do this would be to create an assembly using the maven-assembly-plugin and the predefined jar-with-dependencies descriptor. You'll also need to generate a manifest with a main-class entry for this uber jar. The snippet below shows how to configure the assembly plugin to do so:

  
    
      maven-assembly-plugin
      
        
          jar-with-dependencies
        
        
          
            fully.qualified.MainClass
          
        
      
    
  

Then, to generate the assembly, just run:

mvn assembly:assembly

If you want to generate the assembly as part of your build, simply bind the assembly:single mojo to the package phase:

  
    
      maven-assembly-plugin
      
        
          jar-with-dependencies
        
        
          
            fully.qualified.MainClass
          
        
      
      
        
          package
          
            single
          
        
      
    
  

And simply run:

mvn package
