This is my plugin in POM.xml file:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.20</version>
            <configuration>
                <argLine>
                    -javaagent:"${settings.localRepository}/org/aspectj/aspectjweaver/1.9.22/aspectjweaver-1.9.22.jar"
                </argLine>
                <suiteXmlFiles>
                    <!--suppress UnresolvedMavenProperty -->
                    <suiteXmlFile>${suiteFile}</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>

This lets me to run tests from a specific testng.xml file with terminal command:
mvn test -DsuiteFile=${absolute_path_of_testng.xml}

I want it to be so that instead of giving absolute path, only to give testng file name and run the tests correspondingly:
mvn test -DsuiteFile=${name_of_testmg.file}

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.20</version>
            <configuration>
                <argLine>
                    -javaagent:"${settings.localRepository}/org/aspectj/aspectjweaver/1.9.22/aspectjweaver-1.9.22.jar"
                </argLine>
                <suiteXmlFiles>
                    <!--suppress UnresolvedMavenProperty -->
                    <suiteXmlFile>${basedir}/${suiteFile}</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>

I added ${basedir} to my suiteXmlFiles tag so that it will give my projects base directory dinamically but I think I am doing it wrong
