[Source] NPS branch OGLExtrusion compilation problem when netbeans "fixes" imports

Hi Terry. It has been a few weeks since I tried working with the
NPS branch OGLExtrusion.java code.
Interesting project failure alert: when trying to "fix" imports for
this class, the NPS branch no longer compiles for me. A number of
errors appear regarding class visibility for a number of classes.
These appear in the Netbeans editor and also when building -
compilation console follows.
This is pretty unusual. I haven't seen the fix-imports feature provoke
errors before (after using it hundreds of times). So thought I'd post
this alert to be extra careful with such imports. Perhaps you will
see something relevant in the project configuration that is unusual
or fixable to avoid this anomaly - it is always good practice to
correct and silence superfluous errors/warnings, when possible.
The Netbeans project Java Sources Classpath still includes
lib/aviatrix3d-all_2.2.0-nps.jar
lib/j3d-org-all_1.1.0.jar
I have not locally checked out or built either j3d or aviatrix.
Working, existing import section:
=================================
// External imports
import javax.vecmath.*;
import org.j3d.aviatrix3d.*;
import org.j3d.geom.GeometryData;
// Local import
import org.web3d.vrml.lang.*;
import org.web3d.vrml.nodes.VRMLNodeType;
import org.web3d.vrml.renderer.common.nodes.geom3d.BaseExtrusion;
import org.web3d.vrml.renderer.common.nodes.GeometryUtils;
import org.web3d.vrml.renderer.common.nodes.GeometryHolder;
import org.web3d.vrml.renderer.ogl.nodes.OGLGeometryNodeType;
=================================
Failing import section after Netbeans "fixes" imports, followed by console.
Note that org.j3d.aviatrix3d.* has been stripped out:
=================================
// External imports
import javax.vecmath.*;
import org.j3d.geom.GeometryData;
import org.web3d.vrml.lang.*;

BUILD FAILED (total time: 19 seconds)
=================================
Anyway, fair warning. This would be good to fix, since the editor is
mistakenly reporting errors and preventing aviatrix3d class exploration,
even though subsequent compilation and execution nevertheless succeeds.
p.s. additional troubleshooting follows:
Further clue: for the unmodified current/compiling version, hovering over
the yellow warning light bulb reports the following warning:
Package org.j3d.aviatrix3d does not exist
So apparently that path is not visible internally to the editor, despite
having the .jar files in the project classpath?
FWIW I tried adding lib/ to the folders list under project Java Sources
but that had now effect, it still reports the "does not exist" warning.
Recommendation:
Something else needs to be added to the Netbeans project configuration
to match the class visibility provided within Ant for compilation/running.
all the best, Don
