Description

Please see demonstration at https://github.com/tazle/maven-issue-demo

After mvn package, the resulting maven-issue-demo-1.0.0-SNAPSHOT-bin.zip contains the following libraries:

maven-issue-demo-1.0.0-SNAPSHOT/lib/httpcore-4.3-alpha2-SNAPSHOT.jar
maven-issue-demo-1.0.0-SNAPSHOT/lib/httpclient-4.3-alpha2-20130227.160252-28.jar

For some reason httpcore has a -SNAPSHOT version whereas httpclient has a unique version. This is clearly not desirable, since e.g. the classpath generator in JAR plugin generates either -SNAPSHOT names or unique names but not both.

Some analysis:
Originally versions of both libraries are unique. During resolution, some are changed to -SNAPSHOT versions instead. This appears to affect packages that are both direct and transitive dependencies.

Some debug output from a modified assembly plugin, with additional debug output:
