Description

I set up a very simple test maven project with only a dependency to testNG.

    public class TestTest {
    @Test
    public void test() {
        System.out.println(getClass().getResource("/"));

Depending on how I build this, the call either returns null or the expected directory. How is that?

    // Prints: file:/C:/workspace/test/testproject/target/test-classes/
    mvn clean test -Dtest=TestTest -f pom.xml
    // Prints: file:/C:/workspace/test/testproject/target/test-classes/
    mvn clean test -Dtest=TestTest -f testproject/pom.xml
    // Prints: null
    mvn clean test -Dtest=TestTest -f ./pom.xml
    // Prints: null
    mvn clean test -Dtest=TestTest -f ./testproject/pom.xml

Note that the second call includes "./" after -f.

I actually want to find out the /target folder regardless of scenario (testNG in IntelliJ, Maven, Jenkins Buid, ...). So far, this way has proven the most reliable.

        System.out.println(getClass().getResource("./"));

This seems to reliably point to file:/C:/workspace/test/testproject/target/test-classes/com/testproject/test. Would this be safer to use?
