Michael Berg commented on MDEP-194:
-----------------------------------
Art, have you actually witnessed this? I have the following in my pom:
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>com.interform400.xml</groupId>
<artifactId>plugin-web-base</artifactId>
<version>${project.version}</version>
<type>war</type>
</artifactItem>
</artifactItems>
<includes>**/web.xml</includes>
<outputDirectory>${project.build.directory}/plugin-web-base-unpack</outputDirectory>
</configuration>
When the build finishes, then inside the plugin-web-base-unpack folder I am
seeing this:
plugin-web-base-unpack/
/WEB-INF/
/WEB-INF/web.xml
The WEB-INF folder was created automatically.
> ArchiverException when using maven dependency plugin in multi-module projects

> Key: MDEP-194
> URL: https://jira.codehaus.org/browse/MDEP-194
> Project: Maven 2.x Dependency Plugin
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Sascha Hofer
> Attachments:
> maven-dependency-plugin-2.5-SNAPSHOT-copy-artifact.patch,
> plexus-archiver-1.0-alpha-9-DirectoryUnArchiver.diff

> Having the following module hierarchy the _unpack-dependencies_ goal of the
> _maven-dependency-plugin_ produces an _ArchiverException_.
> * A
> ** B
> ** C (depends on B)
> I took a quick look into the code and found that when unpacking the
> dependencies of module *C* the method _unpack(File, File, String, String)_ of
> class _org.apache.maven.plugin.dependency.AbstractDependencyMojo_ gets passed
> the *target/classes* directory of *B* as source file (instead of the created
> jar).
