I am using apache log4j in my code.

Could you please help me how can I ignore all the log statements in a java class during jacoco coverage.

below is ant configuration for jacoco -

<target name="test" depends="compile">
<jacoco:coverage destfile="${result.exec.file}" excludes="org.apache.log4j.*">
<junit showoutput="true" printsummary="on" enabletestlistenerevents="true" fork="true" haltonfailure="no" forkmode="once">
<classpath path="${result.classes.dir}"/>
<classpath path="${junit.jar.path}"/>
<classpath path="${hamcrest.jar.path}"/>
<classpath location="../../ant-junit-1.9.5.jar"/>
<formatter type="plain" usefile="false"/>
<test name="com.ant.sonar.jacoco.junit.code.coverage.JacacoCoverageTest"/>
</junit>
</jacoco:coverage>
<!-- Step 3: Create coverage report -->
<jacoco:report>
<!--
 This task needs the collected execution data and ... 
-->
<executiondata>
<file file="${result.exec.file}"/>
</executiondata>
<!-- the class files and optional source files ... -->
<structure name="JaCoCo Ant Example">
<classfiles>
<fileset dir="${result.classes.dir}"/>
</classfiles>
<sourcefiles encoding="UTF-8">
<fileset dir="${src.dir}"/>
</sourcefiles>
</structure>
<!-- to produce reports in different formats. -->
<html destdir="${result.report.dir}"/>
<csv destfile="${result.report.dir}/report.csv"/>
<xml destfile="${result.report.dir}/report.xml"/>
</jacoco:report>
</target>

Please let me know if anything needed from my end.

If you use log4j it needs to be on the classpath, otherwise you will get a NoClassDefFOundError.

This is not related to JaCoCo. Please make your build work without JaCoCo. JaCoCo cannot fix your classpath.

Regards,

Hi Mark,

It is not related to build. Build is still working fine. I am getting error for jacoco coverage.

In my classpath, I already have the log4j related jar.

I tried adding jvm-arg for log4j properties in debug configuration. After that I was able to see the coverage in eclipse also for eclemma plugin in my local eclipse workspace, but it is not working for jacoco coverage.

Let me rephrase what Marc said:

As highlighted below there is no log4j jar in classpath of "junit" task in your ant script.

And so you will be receiving the same ClassNotFoundException even without wrapping "junit" by "jacoco:coverage"

If you disagree with the above observations, then please provide complete example, because partial snippets are not debuggable.

Thank you Evgeny and Marc,

Now I got the issue. I have added log4j jar in junit classpath and it is working this time :)

Once again thank you so much for helping me with this issue.
