How to make Sonar ignore some classes for codeCoverage metric?

Question

I have a Sonar profile in Maven. Everything works fine except the code coverage metric. I want to make Sonar ignore some classes only for the code coverage metric. I have th

Answer 1

Accordingly to this document for SonarQube 7.1

sonar.exclusions - Comma-delimited list of file path patterns to be excluded from analysis sonar.coverage.exclusions - Comma-delimited list of file path patterns to be excluded from coverage calculations

This document gives some examples on how to create path patterns

# Exclude all classes ending by "Bean"
# Matches org/sonar.api/MyBean.java, org/sonar/util/MyOtherBean.java, org/sonar/util/MyDTO.java, etc.
sonar.exclusions=**/*Bean.java,**/*DTO.java

# Exclude all classes in the "src/main/java/org/sonar" directory
# Matches src/main/java/org/sonar/MyClass.java, src/main/java/org/sonar/MyOtherClass.java
# But does not match src/main/java/org/sonar/util/MyClassUtil.java
sonar.exclusions=src/main/java/org/sonar/*

# Exclude all COBOL programs in the "bank" directory and its sub-directories
# Matches bank/ZTR00021.cbl, bank/data/CBR00354.cbl, bank/data/REM012345.cob
sonar.exclusions=bank/**/*

# Exclude all COBOL programs in the "bank" directory and its sub-directories whose extension is .cbl
# Matches bank/ZTR00021.cbl, bank/data/CBR00354.cbl
sonar.exclusions=bank/**/*.cbl

If you are using Maven for your project, Maven command line parameters can be passed like this for example -Dsonar.coverage.exclusions=**/config/*,**/model/*

I was having problem with excluding single class explicitly. Below my observations:

**/*GlobalExceptionhandler.java - not working for some reason, I was expecting such syntax should work
com/some/package/name/GlobalExceptionhandler.java - not working
src/main/java/com/some/package/name/GlobalExceptionhandler.java - good, class excluded explicitly without using wildcards

Answer 2

At the time of this writing (which is with SonarQube 4.5.1), the correct property to set is sonar.coverage.exclusions, e.g.:

<properties>
    <sonar.coverage.exclusions>foo/**/*,**/bar/*</sonar.coverage.exclusions>
</properties>

This seems to be a change from just a few versions earlier. Note that this excludes the given classes from coverage calculation only. All other metrics and issues are calculated.

In order to find the property name for your version of SonarQube, you can try going to the General Settings section of your SonarQube instance and look for the Code Coverage item (in SonarQube 4.5.x, that's General Settings → Exclusions → Code Coverage). Below the input field, it gives the property name mentioned above ("Key: sonar.coverage.exclusions").
