Hello I’m noob and I can’t figure it out. I’ve got the SDK from jMonkey platform SVN checkout following the instructions from: build_platform :: jMonkeyEngine Docs.
After opening the dowloaded sdk project I hit build and get the following:
C:Projectstrunksdkbuild.xml:7: The following error occurred while executing this line:
C:Projectstrunksdknbprojectbuild-impl.xml:41: Cannot find NetBeans build harness.
If I set the harness using a property pointing to a NetBeans harness and try to build I get the following:

I think I’m 2 hours ahead of you (http://hub.jmonkeyengine.org/groups/jmonkeyplatform/forum/topic/trouble-building-module-from-command-line/) 
Maybe you forgot to do ‘ant update-platform’ once so it downloads the netbeans platform.
