Making HTTP post request (with an input type=“file”) from within Maven, using command line parameters if possible

Question

I would like to convert this bash script:

#!/bin/bash
if ! [ $# == 2 ]; then
   echo Usage: update-module admin-password module-file
   exit 1
fi
if ! [ -f $2 ];         


        

Answer 1

Use GMaven to embed an inline Groovy Script, and use apache httpclient to implement the post request. Something like this:

    org.codehaus.groovy.maven
    gmaven-plugin
    
        
            org.apache.httpcomponents
            httpclient
            4.0.2
        
    
    
        
            generate-resources
            
                execute
            
            
                
            
        
    

This uses the maven properties http.url and http.attachmentFile that you can specify on the command line using the -D syntax or in a pom.xml file in a block. Obviously, you'd need to extend the functionality to what else your shell script is doing, but this should get you started.
