Correct way to handle excluded classes within a package

[John D. Ament]

In my code, I have some classes that are coded and others that are code generated via JPA's metamodel gen.  When this gen runs, it places the generated classes in the same package.  I want to exclude these classes from code coverage reporting.  What is the proper way to ensure that they don't show in the reports?

[Marc R. Hoffmann]

Hi,

these classes must be excluded from report generation, here you have two
options: If the generated classes follow a common naming pattern you can
list the in the excludes attributes of the respective build tool you're
using. A cleaner way would be place the generated classes into a
different location and only supply the location of your app classes to
the reporting tool.

What build tool are you using to generate the report?

Hi & thanks for the response.

I'm using Maven.  I have this section:

<reporting>

<excludeDefaults>false</excludeDefaults>

<plugins>

<plugin>

<groupId>org.jacoco</groupId>

<artifactId>jacoco-maven-plugin</artifactId>

<version>0.6.2.201302030002</version>

</plugin>

So what I did originally was:

<plugin>

<groupId>org.jacoco</groupId>

<artifactId>jacoco-maven-plugin</artifactId>

<version>0.6.2.201302030002</version>

<configuration>

<excludes>*_</excludes>

</configuration>

</plugin>

However they were still included.  I assumed this would ignore anything ending with a _.

Hi,

there are some known inconsistencies regarding includes/excludes:

Basically for the Maven report goal the excludes refer to class file
names. So probably the pattern should be

<excludes>*_.class</excludes>

So, I tried that.  IT did help but the classes still show as 0%.  I don't want to show them at all.

Where does it show 0%? In the generated JaCoCo report?

Yes, this is the configuration I ended up adding (it's not clear if this parameter is supposed to be an array style like other excludes in maven, or a comma separated list):

<plugin>

<groupId>org.jacoco</groupId>

<artifactId>jacoco-maven-plugin</artifactId>

<version>0.6.2.201302030002</version>

<configuration>

<excludes>

<exclude>*_.class</exclude>

</excludes>

</configuration>

</plugin>

However in the report it still showed.  I would prefer that the class not show in the report.

Did anyone had solution for this. i want some of the generated sources need to be excluded from the report instead of showing as 0%

Please check https://github.com/jacoco/jacoco/tree/master/jacoco-maven-plugin.test/it/it-includes-excludes - files "FileUtil" and "TestUtil" are excluded from reports.
