Michael Osipov commented on MPMD-399:
-------------------------------------
I have a slight problem with {{includeTests}}: It documentation says "Run PMD
on the tests.". Looking at
https://github.com/apache/maven-pmd-plugin/blob/1961d771ea585e9344c25dfde194ee64a1b9040b/src/main/java/org/apache/maven/plugins/pmd/AbstractPmdReport.java#L351-L384.
The operation is additive/inclusive. The description is wrong. But here, it is
exclusive:
https://github.com/apache/maven-pmd-plugin/blob/1961d771ea585e9344c25dfde194ee64a1b9040b/src/main/java/org/apache/maven/plugins/pmd/PmdReport.java#L516-L518
[~adangel], shouldn't {{auxClasspath}} include main classpath as well when
tests should be included? Since dependencies are inclusive as well:
https://github.com/apache/maven-pmd-plugin/blob/1961d771ea585e9344c25dfde194ee64a1b9040b/src/main/java/org/apache/maven/plugins/pmd/PmdReport.java#L493-L497
It does not compute fo me.
[~AB-xdev], sorry to deviate, but that needs to clarified first.

> Key: MPMD-399
> URL: https://issues.apache.org/jira/browse/MPMD-399
> Project: Maven PMD Plugin
> Issue Type: Bug
> Components: PMD
> Affects Versions: 3.22.0
> Reporter: AB-xdev
> Priority: Major
>
> PMD plugin is reporting the following warnings on in a multi-maven project:
> "The project X does not seem to be compiled. PMD results might be inaccurate."
> This is caused by the fact that not all modules have a
> * {{src/main/java}} or
> * {{src/test/java}} folder
> and therefore no {{target/classes}} or {{target/test-classes}} folders are
> generated.
> The affected code that causes the problem can be found here:
> [https://github.com/apache/maven-pmd-plugin/blob/1961d771ea585e9344c25dfde194ee64a1b9040b/src/main/java/org/apache/maven/plugins/pmd/PmdReport.java#L516-L532]
> h3. Reproduction example
> * Create a maven multi-module project
> * Leave {{src/main/java}} of one module empty
> * Execute {{pmd:aggregate-pmd}} or {{test pmd:aggregate-pmd-no-fork
> -DskipTests}}
> → (x) Warning is reported
> h3. Possible fixes
> * Make it possible to ignore this warning
> * Do not warn when at least {{target/classes}} or {{target/test-classes}} is
> present
