How to pass Maven settings via environmental vars

Question

In our setting.xml file we have the following:

    
      deploymentRepo
      repouser<         


        

Answer 1

Yes, you can do this in two ways:

• passing properties in command line, using variables. For example, you can use in your settings.xml something like this:

    
      deploymentRepo
      ${server.username}
      ${server.password}
    

And in command line, pass these variables in this way:

mvn clean package -Dserver.username=yourusername -Dserver.password=yourpassword

• exporting environments properties. For example, if you export (in linux, something like export SERVER_USERNAME=yourusername) SERVER_USERNAME and SERVER_PASSWORD variables, you can use like this:

    
      deploymentRepo
      ${env.SERVER_USERNAME}
      ${env.SERVER_PASSWORD}
