I need to work with .7z files in an Ant build I write and run in IDEA. To do that, I've installed Apache Compress Antlib in Ant's lib directory, and added this to the relevant build target:
<taskdef resource="org/apache/ant/compress/antlib.xml" />
The <sevenz> task I need works fine in the build, but IDEA highlights it and the <taskdef> line above as errors in my build file. Clearly Ant has loaded the library and its taskdefs, but IDEA's parser doesn't see them for some reason.
Is there something I need to do to fix this? Or is it a bug?
