Hi

After I migrated to 2.2.0 I get the following warning:

[INFO] — gatling-maven-plugin:2.2.0:execute (default) @ MerchantRegistration —  
15:01:02.581 [main][WARN][ZincCompiler.scala:142] i.g.c.ZincCompiler$ - Pruning sources from previous analysis, due to incompatible CompileSetup.

Using the maven artefact:

```auto
mvn archetype:generate -DarchetypeGroupId=io.gatling.highcharts \
 -DarchetypeArtifactId=gatling-highcharts-maven-archetype -DinteractiveMode=false \
 -DarchetypeVersion=2.2.0 -DgroupId=io.gatling.highcharts \
 -DartifactId=<name of project> -Dpackage=<your domain>

scala-sdk 2.11.7, java jdk 1.8.0_72 

```

Thanks

Hi,

Honestly, I don’t really know if this warning (new in zinc 0.3.9) really makes sense.  
And as zinc is undergoing huge changes before going version 1, I don’t think we’ll investigate much there.

Regards,
