mvn assembly:assembly fails if there is no target directory already present
---------------------------------------------------------------------------
Key: MNG-1578
URL: http://jira.codehaus.org/browse/MNG-1578
Project: Maven 2
Type: Bug
Reporter: Matthew Pocock
Priority: Minor
I have a module that is of type pom. Its job is to agregate a set of
dependencies. I want to build a distribution from these, so I tried the
assembly plugin. I did get it to work. However, on the way I got this error:
[INFO] [assembly:assembly]
[INFO]
----------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO]
----------------------------------------------------------------------------
[INFO] Error creating assembly:
/home/nmrp3/devel/derkholm/bjv2/trunk/clis/cli/target isn't a directory.
A build for a pom project doesn't make a target directory. But,
assembly:assembly requires one. I've made the directory manually and now the
assembly builds just fine. The stack-trace is below. I've modified my assembly
descriptor file to not mention target/** at all, and it now builds just fine
without the target directory being present.
The path of least suprise for the end-user would be to behave as if there were
no files to find if target is absent and a search is done within target for
files.
