Hal Deadman commented on MASSEMBLY-556:
---------------------------------------
I am getting this same NPE when I try to create an assembly with a maven
repository in it using the assembly plugin's <repositories> tag. I am using
Maven 3.0.3 and assembly plugin 2.3.
Other assemblies (non-repositories) are working. The culprit does appear to be
the mirror entry in settings.xml, although I had to use a settings.xml that
didn't have a mirror and add a repositories section to my pom.xml:
{code}
<repositories>
<repository>
<id>nexus</id>
<url>http://XYZ.PDQ/nexus/content/groups/public</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
{code}
The assembly descriptor I am using looks like this:
{code}
<assembly
xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2
http://maven.apache.org/xsd/assembly-1.1.2.xsd";>
<id>repository</id>
<formats>
<format>zip</format>
</formats>
<repositories>
<repository>
<scope>runtime</scope>
<includeMetadata>true</includeMetadata>
<outputDirectory>maven2</outputDirectory>
</repository>
</repositories>
</assembly>
{code}
If settings.xml has a mirror, I get the NPE. If I don't have a mirror I have to
add the repositories section to my pom.xml because Maven tries to re-download
things that it can't find unless I point the application at our nexus server
(rather than relying on a mirror of * to point at our nexus server). I have all
the dependencies in my local repo so I am not sure why it is trying to download
anything.
