Tuure Laurinolli created MASSEMBLY-645:
------------------------------------------
Summary: File name of dependency depends on how it is reachable
Key: MASSEMBLY-645
URL: https://jira.codehaus.org/browse/MASSEMBLY-645
Project: Maven 2.x Assembly Plugin
Issue Type: Bug
Components: dependencySet
Affects Versions: 2.4
Reporter: Tuure Laurinolli
Priority: Critical
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:
