[ jEdit-users ] Unexpected element 'import'

[Trevor H. <tr...@vo...>]

Hi all,

For some time now, I've been getting "Unexpected element 'import'" 
errors in my Ant build files. They would pop up in the ErrorList all 
the time, which got pretty annoying. After all, <import> is a perfectly 
valid tag ever since Ant 1.6.

I knew the problem, then, was that jEdit (or rather, a jEdit plugin) 
was parsing my build files based on an old version of Ant, because only 
the new Ant 1.6 elements were being flagged. I figured that there must 
have been an old version of Ant 1.5 floating around in my system 
somewhere. And yet, after checking that my only copy of Ant was 1.6.2, 
I was still getting the errors.

Eventually, I discovered the problem: When the AntFarm plugin is 
installed, it downloads its own copy of ant.jar from Ant 1.5.4 and 
places it into jEdit's plugin directory. AntFarm then uses this older 
jar no matter what you have installed elsewhere on your system. The 
quick-and-dirty fix is to replace ant.jar with a new one from Ant 1.6. 
Actually, it's not quite that simple because AntFarm also tries to load 
the old ant-optional.jar from Ant 1.5. To fix that, you have to extract 
AntFarm.props from the AntFarm.jar, remove the ant-optional.jar 
reference from the plugin.antfarm.AntFarmPlugin.jars line, and put 
AntFarm.props back into the jar.

Anyway, I hadn't seen any discussion of this problem before, so I 
figured I should post the workaround in case somebody else runs into 
it.
