I don't understand, I try to generate code coverage report with JaCoCo and Maven, the simplest.
I have the following plugin in my pom.xml :
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>${jacoco.version}</version>
<executions>
<execution>
<id>prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
<execution>
<id>post-unit-test</id>
<phase>test</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<!-- Sets the path to the file which contains the execution data. -->
<dataFile>target/jacoco.exec</dataFile>
<!-- Sets the output directory for the code coverage report. -->
<outputDirectory>target/my-reports</outputDirectory>
</configuration>
</execution>
</executions>
<configuration>
<systemPropertyVariables>
<jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
</systemPropertyVariables>
</configuration>
</plugin>
And when I try to do a mvn test, it just doesn't do anything. Not even an error or something. It say BUILD SUCESS for my tests but Maven seems to not see JaCoCo. If I try to execute mvn jacoco:report anyway I have a message : Skipping JaCoCo execution due to missing execution data file.
The following configuration should be enough:
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>${jacoco.version}</version>
<executions>
<execution>
<id>prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>report</id>
<phase>test</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
The reports can then be found in target/site/jacoco/
Reasons why it does not work in your case:
pluginManagement
profile
Also check the maven log when you execute mvn test
for jacoco-maven-plugin
. For more information run mvn -X test
