EclipseHelperMojo doesn't load EclipseHelper when project linked #10

When building SCIFIO in Eclipse with project-linkage to SciJava-common, I get an exception with the message: Could not load EclipseHelper.

This comes from a failure to load the org.scijava.annotations.EclipseHelper.class in the EclipseHelperMojo when SJC is project-linked in Eclipse as a dependency of the project I was building.

I checked the built classpath and confirmed that it did point to a path on disk that would find the EclipseHelper class.

The temporary workaround is to close the SJC project in Eclipse.

Occurred on Windows 8.1, Eclipse 4.4.0 and scijava-maven-plugin 0.4.4.
