-----------------------------------
Summary: Add an option to clean the outputDirectory before unpack
Key: MDEP-675
URL: https://issues.apache.org/jira/browse/MDEP-675
Project: Maven Dependency Plugin
Issue Type: New Feature
Components: unpack
Affects Versions: 3.1.1
Reporter: Olivier Becker
I have a project that needs to extract a very big maven zip artifact.
I use the maven dependency plugin (unpack goal) with the marker to avoid the
extraction at each compilation.
This very big artifact is currently in development, so I use its SNAPSHOT
version.
Sometimes a new version of this SNAPSHOT is pushed to Nexus, so when I compile
my project (using mvn install), the maven dependency plugin unzips the new
SNAPSHOT version but the problem is that the outputDirectory contains a mix
between the old version and new version of the artifact.
For example, the first version of the SNAPSHOT contains two files:
Foo1.bin, Foo2.bin
The second version of the SNAPSHOT contains two files:
Foo1.bin, Bar1.bin
The outputDirectory contains:
Foo1.bin, Foo2.bin, Bar1.bin
Whereas I would need to have only Foo1.bin and Bar1.bin.
Because it's a very big file, it's not possible to always compile using "mvn
*clean* install" instead of "mvn install" because extraction takes too much
time. I need a way to process the extraction only when the big artifact has
been modified.
That is why it would be nice to have an option to clean the outputDirectory
before the extraction.
I have a pull request that I can submit if you agree to add this new feature.
