Resolve Netbeans Ant:taskdef class Org.netbeans.modules.java.j2seproject.copylibstask.CopyLibs cannot be found

You get an error when you build your project with NetBeans (actually ant) Clean and build executable files (for example, EXE files under Windows)

Or if you encounter such an error:

The Libs. Copylibs.classpath property isn't set up

Reference: Http://www.adam-bien.com/roller/abien/entry/how_to_fix_the_libs

Workaround: Add such an entry in tools>options>java>ant>properties:

Libs. Copylibs.classpath=[netbeans_home]/java/ant/extra/org-netbeans-modules-java-j2seproject-copylibstask.jar

Where Netbeans_home is the installation directory for NetBeans, such as Windows

D\:/program Files (x86)/jmonkeyplatform

Of course Jmonkeyplatform is the NetBeans-based IDE, which is essentially netbeans.

Note the colon to use the escape character \:
