Inconsistent includes/excludes options for Maven report goal

[marchof]

For the JaCoCo agent, Ant Tasks and Maven goals the format of the class names to include/exclude needs to be properly specified.

Also the change log for 0.5.4 probably shows the wrong format.

[marchof]

These are the different notations for classes we have:

• VM Name: java/util/Map$Entry
• Java Name: java.util.Map$Entry
• File Name: java/util/Map$Entry.class

Agent Parameters, Ant tasks and Maven prepare-agent goal

• includes: Java Name (VM Name also works)
• excludes: Java Name (VM Name also works)
• exclclassloader: Java Name

These specifications allow wildcards * and ?, where * wildcards any number of characters, even multiple nested folders.

Maven report goal

includes: File Name
excludes: File Name

These specs allow Ant Filespec like wildcards *, ** and ?, where * wildcards parts of a single path element only.

I'm trying to exclude all the content of the com.mycompany.ignore_this package but so far no luck. This is what I put in my root pom.

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>default-prepare-agent</id>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
        </execution>
        <execution>
            <id>default-report</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>report</goal>
            </goals>
        </execution>
        <execution>
            <id>default-check</id>
            <goals>
                <goal>check</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <excludes>
            <exclude>com.mycompany.ignore_this.*</exclude>
        </excludes>
    </configuration>
</plugin>

I also tried to exclude it in the prepare-agent and report executions, but didn't work: the packages keep on showing on the reports.
Jacoco docs did not help much in my case. Have I missed something?

@spaceCamel The report goal is the correct place to exclude classes or packages from the report (I assume this is what you want to achieve). As stated in my issue above for the report goal the excludes list refers to file names. So in your case the configuration would be:

<exclude>com/mycompany/ignore_this/*</exclude>

@marchof thanks for pointing that out again. Indeed if I put <exclude>com/mycompany/ignore_this/*</exclude> in the report configuration I get all the classes under the package com.mycompany.ignore_this excluded. I was misled by the fact that SonarQube code-quality service is still displaying these classes.
I noticed it picks up the jacoco.exec files during analysis. Do you know what those files contains?
