Maven command to run a single Testng.xml

Question

I am using Surefire Plugin, and I have a suite like this:

 <suiteXmlFiles>
      <suiteXmlFile>src/test/resources/suites/testng1.xml</suiteXmlFile>
      <suiteXmlFile>src/test/resources/suites/testng2.xml</suiteXmlFile>
 </suiteXmlFiles>

If I execute this command:

mvn clean test

then both xml files are executed. Now I want to run only testng2.xml, so I specify its path in this command:

mvn clean test -Dsurefire.suiteXmlFiles=/src/test/resources/suites/testng2.xml

but it doesn't work, because both testng1.xml and testng2.xml are again executed.

Am I missing something? I use Maven v3.5. Thanks

One way to do it:

<configuration>
    <suiteXmlFiles>
        <suiteXmlFile>${suiteXmlFile}</suiteXmlFile>
    </suiteXmlFiles>
</configuration> 

And in the command line:

mvn test -DsuiteXmlFile=src/test/resources/suites/testng2.xml

This code 'replaces' the variable ${suiteXmlFile} with the value provided.

Now if you want to have a default suite in your pom.xml which is executed when you do mvn test, but is overriden if you do mvn test executeAnotherSuiteInsteadOfDefault, check this answer: https://stackoverflow.com/a/13829933/5494070.
