Subject [jira] Commented: (MASSEMBLY-264) Filtering in Assembly Generates Blank Files in the Archive
Date Mon, 08 Sep 2008 10:46:49 GMT


Neill Alexander commented on MASSEMBLY-264:

Hi Petar,

I can't reproduce it either. I've retested with the original build, and it's all working fine
with 2.2-beta-2. And it looks like it was working on my test project as well when I reported

Apologies. I must have been suffering from brain freeze when I reported this.

> This appears to be a result of some recent changes to the src/main/java/org/apache/maven/plugin/assembly/archive/task/
file (changeset 591556) which deletes the files from the temporary directory. The problem
with this is that the archive object has a reference to the filtered files in the temporary
directory. When the call to archive.createArchive( ) is made it can't find the filtered files,
and therefore they end up empty in the archive.
> The attached archive contains a test maven project you can run which will demonstrate
this bug. Run 'mvn clean assembly:assembly' and check out the contents of target/
> The simply fix is simply to roll-back the 'finally' clause added as part of 591556 to
src/main/java/org/apache/maven/plugin/assembly/archive/task/ Whether
or not it is the best fix, I don't know (hence the absence of a patch).
