Difficult to create .JAR in NetBeans

Question

Good morning guys,

I'm trying to create a JAR in NetBeans, but I get messages:

C: \ Users \ Administrator \ Desktop \ Project \ nbproject \ build-impl.xml: 993: The Following error occurred while executing this line: 
C: \ Users \ Administrator \ Desktop \ Project \ nbproject \ build-impl.xml: 837: copylibs does not support the "excludeFromCopy" attribute 

NetBeans does not generate the .JAR because of the errors.

My specs:

Version of OS = Windows 7 64 Bit
Java version = 1.7.0_55
Netbeans version = 7.0.1

Answer 1

This looks like an existing bug. The simplest course of action would probably be to upgrade to the latest version of Netbeans.

Alternatively, you can create a new project and copy your source files over - it may solve the problem.
