Custom Source Roots
By default, CodeNarc Maven Plugin assumes src/main/groovy to be the compile sources root, and src/test/groovy to be the test sources root. If you need to include additional sources in the analysis, or use a nonstandard project layout, you can use the <sources> and <testSources> properties:
<plugin>
<groupId>io.github.crizzis</groupId>
<artifactId>codenarc-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>verify</goal>
</goals>
</execution>
</executions>
<configuration>
<sources>
<fileSet>
<directory>src/main/groovy</directory>
</fileSet>
<fileSet>
<directory>src/main/additional</directory>
</fileSet>
</sources>
<testSources>
<fileSet>
<directory>src/test-sources/groovy</directory>
<excludes>
<exclude>**/*ExcludedTest.groovy</exclude>
</excludes>
</fileSet>
</testSources>
<includeTests>true</includeTests>
</configuration>
</plugin>
Note that while the element type of <sources> and <testSources> is a FileSet, only the <directory>, <includes>, and <excludes> have any effect.
The <sources> and <testSources> properties combine with <includes> and <excludes>. In other words, the following configurations:
<sources>
<fileSet>
<directory>src/main/additional</directory>
</fileSet>
<exludes>
<exclude>**/*.gr</exclude>
</exludes>
</sources>
and:
<sources>
<fileSet>
<directory>src/main/additional</directory>
<exludes>
<exclude>**/*.gr</exclude>
</exludes>
</fileSet>
</sources>
are equivalent. Also note that if you do not override the <includes> property, the default **/*.groovy is still in effect, meaning that it will apply to all custom filesets in addition to fileset-specific rules.
