maven surfire testng execution not working

I have problems setting up my project for testng usage. Background is that I want to execute my test.xml with maven command line. I use this plugin within the build section of my pom.xml:

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-surefire-plugin</artifactId>
   <version>3.0.0-M5</version>
   <configuration>
     <suiteXmlFiles>
        <suiteXmlFile>test.xml</suiteXmlFile>
     </suiteXmlFiles>
   </configuration>
</plugin>

However... when I call mvn clean test -DxmlSuiteFile=test.xml all my unit tests are executed but the test.xml is untouched.

when I change the version of surefire to 2.22.2 everything works fine. BUT I get the message: testSuiteXmlFiles0 has null value when running only mvn test

I am confused how to get that to run with the surefire 3.0.0-M5 ?

Solution

-DxmlSuiteFile=test.xml is not required if it already defined in pom.xml.

Try to define surefire testNG provider explicitly:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M5</version>
    <configuration>
        <suiteXmlFiles>
            <suiteXmlFile>test.xml</suiteXmlFile>
        </suiteXmlFiles>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.apache.maven.surefire</groupId>
            <artifactId>surefire-testng</artifactId>
            <version>3.0.0-M5</version>
        </dependency>
    </dependencies>
</plugin>

test.xml file should be in the project root.
