Robert Scholte commented on MCOMPILER-69:
-----------------------------------------
If you check
http://maven.apache.org/developers/mojo-api-specification.html#The_Descriptor_and_Annotations
and see the options for requiresDependencyResolution you'll see the problem:
There's no _requiredClassPath_ value just for just test-compilation. The
_test_-value is used for executing tests and for that reason all dependencies
are selected.
> Runtime dependencies included on classpath during compiler:testCompile
> ----------------------------------------------------------------------
>
> Key: MCOMPILER-69
> URL: https://jira.codehaus.org/browse/MCOMPILER-69
> Project: Maven 2.x Compiler Plugin
> Issue Type: Bug
> Affects Versions: 2.0.2
> Reporter: marekk
>
> When executing compiler:testCompile, all runtime dependencies are added to
> the classpath to compile the test source code. This is contrary to the
> purpose of the runtime scope, which is simply to include the dependency when
> running the code, not compiling.
> Here is what Maven's website[1] says about the runtime scope:
> "this scope indicates that the dependency is not required for compilation,
> but is for execution. It is in the runtime and test classpaths, but not the
> compile classpath."
> ...And here is what Better Builds with Maven says about the runtime scope:
> "This is because, in this situation, the (runtime) dependency is used only
> for packaging, not for compilation. In fact, if the dependency were required
> for compilation, for stability it would always be declared in the current POM
> as a dependency - regardless of whether another dependency introduces it." -
> page 65
> "Check that the scope of your dependencies are set correctly (to test if only
> used for unit tests, or runtime if it is needed to bundle with or run the
> application but not for compiling your source code)." - page 204
