Groovy code is not instrumented and no database is created

[Oliver Fehse]

Hello!

I want to apply Clover to Groovy code in a non-default directory (namely vars). I use Spock as test framework. I use GMavenPlus to add and compile the sources, which are recognized by Clover but not instrumented. I get the following messages:

[INFO] No Clover instrumentation done on source files in: [C:\Users\..\src\main\java, C:\..\vars] as no matching sources files found (JAVA_LANGUAGE)

The build section of my POM looks like this:

</build>

I call the build via CLI with the following command:

mvn clean test clover:aggregate clover:clover

The sources are added before clover:setup is called.

My system setup is:

Maven: 3.6.0

JDK: OpenJDK 12.0.1

Clover: 4.3.1

Groovy: 2.5.6

OS: Windows 10

Thanks in advance!

Kind Regards,

Oliver

The 

No Clover instrumentation done on source files in ... JAVA_LANGUAGE

is a warning for missing Java code, so you shall not worry about it in your case. 

In your case it seems to be a problem with attaching Clover to Groovy compiler.

Enable debug logging (`mvn -X` option) and look for a message like '

Clover including the following files for Groovy instrumentation: ...

Check if any source files are listed here. If not, then there's some problem with your inclusion pattern or source roots. 

See sources of com.atlassian.maven.plugin.clover.CloverInstrumentInternalMojo#injectGrover to learn more how it work.
