未计算声纳覆盖范围

Question

I am trying to integrate my code coverage into the sonar but it shows 0. I have integrated jacoco as below to my pom but, it still shows the code coverage as zero.

I have only used the pom file from this repository, what other configuration should I work in order to have code coverage?

What would be other parameters should I possibly add?

Thanks.

There are a number of things that can cause this.

The first thing you should do is examine the workspace to see if the Jacoco plugin wrote its output files anywhere in the "target" tree. It will generate a data file in one or more formats, but it will also generate an html tree, with an "index.html" in the root. You can visit that file, and it will show your coverage results.

If you don't find those files, then either your jacoco plugin is not properly integrated with your surefire plugin, or you simply didn't run your unit tests in the build (don't laugh, I've seen people do this).

The "integration" is done by telling Jacoco what variable to put the required command line into, and telling Surefire to use that variable.

Here is a sample jacoco plugin definition:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>${jacoco.maven.plugin.version}</version>
    <executions>
        <execution>
            <id>pre-unit-test</id>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
            <configuration>
                <propertyName>surefireArgLine</propertyName>
            </configuration>
        </execution>
        <execution>
            <id>post-unit-test</id>
            <phase>test</phase>
            <goals>
                <goal>report</goal>
            </goals>
            <configuration>
                <outputDirectory>${jacoco.path}</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

Note the reference to "surefireArgLine". Here is the Surefire definition that goes with that:

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${maven.surefire.plugin.version}</version>
    <configuration>
        <argLine>${surefireArgLine}</argLine>
    </configuration>
</plugin>

We also combine this with these property settings:

    <jacoco.path>${basedir}/target/jacoco_report</jacoco.path>
    <sonar.coverage.jacoco.xmlReportPaths>${basedir}/target/jacoco_report/jacoco.xml</sonar.coverage.jacoco.xmlReportPaths>
