Cannot be indexed twice - testSourceDirectory and sourceDirectory are the same

Question

I created a performance test as a maven submodule for my main module. All test classes are written in the src / main / java section, not src / test / java

I can pack the project as a jar and run it to test the performance of my project.

I wanted to run mvn test . For mvn test to work, I must have a value of <testSourceDirectory> . As in this case, I have the code in src / main / java that I installed for this:

 <testSourceDirectory>src/main/java</testSourceDirectory> 

Now mvn test works.

But the problem is that building a sonar is not a mistake: can't be indexed twice . Which is obvious, since my pom testSourceDirectory and sourceDirectory same.

 [ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.5:sonar (default-cli) on project Blah: File [relative=XYZ.java, abs=/Path/XYZ.java] can't be indexed twice. Please check that inclusion/exclusion patterns produce disjoint sets for main and test files -> 

How to fix this problem?

Answer 1

I ran into the same problem. Finally solved this using the following documentation: -

https://github.com/SonarOpenCommunity/sonar-cxx/wiki/FAQ

Q: ERROR: Caused by: File [...] can't be indexed twice.

A: In case of an error below, you must confirm your exception / inclusion of the property. Please verify that inclusion / exclusion patterns produce unrelated sets for source and test files.

ERROR: Reason: the file [...] cannot be indexed twice. Please check this inclusion / exclusion patterns create disjoint sets for the main and test files. An example might look like this:

 sonar.sources=. sonar.tests=. sonar.test.inclusions=**/*Test*/** sonar.exclusions=**/*Test*/** 

Answer 2

This is not a standard use of Maven, but you can easily fix SonarQube analysis using exceptions. sonar.exclusions = src / main / java / ** or sonar.test.exclusions = src / main / java / **

depending on whether you want the source files to be seen as tests or core files.

But the right way for Maven would be to put your tests in src / test / java and ackage your tests: https://maven.apache.org/guides/mini/guide-attached-tests.html

Answer 3

If the project does not match the Maven default directory structure, in the project pom you can explicitly indicate where part of the source code and part of the tests are:

 <properties> <sonar.sources>src/main/foo</sonar.sources> <sonar.tests>src/test/bar</sonar.tests> </properties>
