archive_war task fails if the target build dir is a nested directory

(this looks like a duplicate of http://jira.codehaus.org/browse/GRADLE-131)

Hi,

I have the following structure:

• root
• (F) build.gradle
• (F) settings.grade
• (D) jarA
• (D) jonah
• - (D) nah
• - (F) build.gradle

root/settings.gradle includes jonah/nah

If I build webapps/webapp1 then it fails with the following error message:

— start
:jonah/nah:archive_war

Build failed with an exception.
Run with -s or -d option to get more details. Run with -f option to get the full (very verbose) stacktrace.

Build file '/Users/colinyates/Projects/orca/jonah/trunk/jonah/nah/build.gradle'

Execution failed for task :jonah/nah:archive_war.
Cause: Problem creating war: /Users/colinyates/Projects/orca/jonah/trunk/jonah/nah/build/jonah/nah-1.0.war (No such file or directory) (and the archive is probably corrupt but I could not delete it)

BUILD FAILED

— end

jonah/nah/build.gradle:

— start
// name still becomes nah-1.0.war
// archivesBaseName = 'nah'

usePlugin('war')
