Get the target directory path in Maven (Java)

Question

In a Maven project I want write some test results into a file in target directory of the project. Whenever, I get the project directory, it is actually getting the IntelliJ project directory instead of actual Maven directory.

Answer 1

You could also use java.nio.file.Paths:

URL url = Paths.get("target", "results.csv").toUri().toURL();

Answer 2

I'm using the classloaders root resource path for retrieving projects build directory with following single line:

Path targetPath = Paths.get(getClass().getResource("/").toURI()).getParent();

The root resource path points to test-classes and it's parent is the desired path regardless of running the test via maven surefire or a JUnit runner of the IDE like Eclipse.
