How to pass Maven settings via environmental vars

Question

In our setting.xml file we have the following:

    
      deploymentRepo
      repouser<         


        

Answer 1

You can pass the URL including the credentials like

mvn deploy -DaltReleaseDeploymentRepository=myrepo::https://user:pass@server/repo

see https://maven.apache.org/plugins/maven-deploy-plugin/deploy-mojo.html

Answer 2

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:

<servers>
    <server>
      <id>deploymentRepo</id>
      <username>${server.username}</username>
      <password>${server.password}</password>
    </server>
</servers>

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:

<servers>
    <server>
      <id>deploymentRepo</id>
      <username>${env.SERVER_USERNAME}</username>
      <password>${env.SERVER_PASSWORD}</password>
    </server>
</servers>

Answer 3

You can pass values from command line

mvn -Dvar=someValue -Dtest.username=xyz install

In the POM file, you can refer to system variables (specified on the command line, or in the pom) as ${var}, and environment variables as ${env.myVariable} i.e,${test.username}
