can't be indexed twice - testSourceDirectory and sourceDirectory are same

Question

I have created performance test as a maven submodule to my main module. All the test classes are written under src/main/java and not src/test/java

I am able to package the project as jar and run it to performance test my project.

I wanted to execute mvn test. For mvn test to work I should have <testSourceDirectory> value set. As in this case I have my code in src/main/java I set this to :

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

Now mvn test works.

But the Problem is sonar build fails with error complaining: can't be indexed twice. Which is obvious as for my pom testSourceDirectory and sourceDirectory are 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 issue?

Some logs may be ? 'file already indexed' is a rather scarce information. — Olivier, Apr 24 '15 at 08:41

I was facing the same problem. Finally, solved it with help of below documentation:-

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

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

A: In case of below error you have to verify your exclusion/inclusion properties. Please check that inclusion/exclusion patterns produce disjoint sets for source and test files

ERROR: Caused by: File [...] can't be indexed twice. Please check that inclusion/exclusion patterns produce disjoint sets for main and test files An example could look like this:
sonar.sources=.
sonar.tests=.
sonar.test.inclusions=**/*Test*/**
sonar.exclusions=**/*Test*/**

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

depending on whether you want your source files to be considered as tests or main files.

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

put `sonar.exclusions=src/main/java/**` or `sonar.test.exclusions=src/main/java/**` in `sonar.properties` and restart the sonar server? Still its not working for me, seeing the same exception – Anand Rockzz Sep 04 '15 at 05:16

Turns out that I had `src` in pom.xml and that was the issue – Anand Rockzz Sep 04 '15 at 05:25
@AnandRockzz you saved my days. I had also same config in build.gradle file. :) – balajimore Jul 06 '18 at 12:18

If project does not follow default Maven directory structure then in project's pom you can explicitly specify where is located the part of source code and the part of tests:

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

I was seeing this can't be indexed twice error when running sonarqube Gradle task on an Android project. The issue related to files stored in app/src/debug/assets.

I tried setting sonar.sources and sonar.tests properties to use disjointed sets but I wasn’t able to resolve the error.

To fix the error I changed:

property "sonar.coverage.exclusions", "**/assets/**, ..."

to:

property "sonar.exclusions", "**/assets/**, ..."

in order to ignore the /assets/ directory completely.

can't be indexed twice - testSourceDirectory and sourceDirectory are same
