create directory when needed in maven

Question

I am using maven-exec-plugin to generate java sources of Thrift. It invokes the external Thrift compiler and using -o to specify the output directory, \"target/generated-sou

Answer 1

Instead of the exec plugin, use the antrun plugin to first create the directory and then invoke the thrift compiler.

  maven-antrun-plugin
  
    
      generate-sources
      generate-sources
      
        
          
          
            
            
            
            
            
          
        
      
      
        run
