How to build jar with Maven containing nothing but dependencies

Today I came across a problem where I had to split my project into two jars: one containing my project's classes and the other one with dependencies. The former got changed every time I made some changes in the source files. The latter was basically constant throughout the development. This facilitates me the deployment of my application. Previously after each improvement I had to transfer a big-fat-and-ugly *-jar-with-dependencies.jar and that took ten good minutes as the file weights 189MB. It turned out that dependencies weight.. 189MB and my compiled classes 45KB. Below the xml that I placed in src/main/resources/assemblies/only-deps.xml

  
  only-deps
  
    jar
  
  false
  
    
      /
      false
      true
      runtime
    
  

and a profile that I added to the main pom.xml:

        
            only-deps
            
                
                    
                        org.apache.maven.plugins
                        maven-assembly-plugin
                        
                            
                                src/main/resources/assemblies/only-deps.xml
                            
                        
                        
                            
                                package
                                create-my-bundle
                                
                                    single
                                
                            
                        
                    
                
            
        

Run the whole thing with mvn install -P only-deps.
