Knut Anders Hatlen updated DERBY-5023:
--------------------------------------

    Description: 
Building Derby doesn't work out of the box in NetBeans. The wiki page 
http://wiki.apache.org/db-derby/BuildingDerby instructs NetBeans users to 
specify the ant.library.dir property in order to get the build working.

The Ant documentation says the following about the ant.library.dir property: 
"The following property is only set if Ant is started via the Launcher class 
(which means it may not be set inside IDEs either)" - 
http://ant.apache.org/manual/properties.html

Since the property is not guaranteed to be set, I suggest that we replace 
references to "${ant.library.dir}/ant.jar" with references to "${ant.core.lib}" 
in the build scripts. According to the above mentioned Ant manual page the 
ant.core.lib property should always be available and point to ant.jar. Changing 
this makes it possible to build Derby from NetBeans with no special 
customization.
