Clover plugin for grails does not collect coverage for unit tests

We are using clover to coverage our grails applications.

Unfortunately it seems that the unit tests, albeit run, are not taken in account in the coverage report.

We run this grails command:

grails --non-interactive --stacktrace --verbose -clover.on test test-app

And we can see this kind of logs:

Grails 2.x has introduced new compiler named '[testc]' (org.codehaus.groovy.grails.test.compiler.GrailsTestCompiler), which is being used to compile unit tests. You can notice it in the build log (with -clover.debug option):

|Compiling 1 source files
    ...
    [testc] ... \test\unit\UnitTests.groovy

|Compiling 1 source files
   ...
  [groovyc] ... \test\integration\IntegrationServiceTests.groovy

Current Grails Clover Plugin (3.1.6) does not intercept this compiler yet. The CLOV-1167 scheduled for Clover 3.1.8 will solve this problem.
