SonarLint for Eclipse: Exception during analysis for missing test-classes directory

[Christian]

Hi SonarLint-Team,

in a maven project we have a src/test/java directory which is empty. This causes maven to skip creating the target/test-classes directory. Still, it is referenced by the eclipse project as a target directory for compiling src/test/java (if that matters).

SonarLint prints an exception to console whenever a Java file from src/main/java in this project is opened (see below).

It seems related to this issue, but not the same problem.

Creating the folder helps, but only until the next mvn clean, obviously.

Best regards,

Christian

Hi Christian,

What is your version of m2e? I tried to reproduce, but even with an empty src/test/java directory, the folder target/test-classes is created.

It's org.eclipse.m2e.feature 1.6.2.20150902-0002, but I suspect it's rather the Maven version 3.3.3. Because at the cli it also does not create the target/test-classes.

I just stumbled over the same issue.

It works if I use only eclipse m2e (version 1.7.x).  But as soon as I build with mvn commandline ('mvn clean install') the test-classes folder is removed and not created again if the src/test/java is empty or not existent.
