-----------------------------------

             Summary: Relocate does not relocate the other JVM variants in Multi Release jar.
                 Key: MSHADE-439
                 URL: https://issues.apache.org/jira/browse/MSHADE-439
             Project: Maven Shade Plugin
          Issue Type: Bug
    Affects Versions: 3.4.1
            Reporter: Niels Basjes


The 2.0 release of snakeyaml is a _Multi Release jar (See this [commit|https://bitbucket.org/snakeyaml/snakeyaml/commits/b33f0ca7507fd61fc945722b5d14de4b0aff5262])_.
For 2 class files they actually package a *standard* and a *java 9* variant of the same thing.
{code:java}
$ unzip -l ~/.m2/repository/org/yaml/snakeyaml/2.0/snakeyaml-2.0.jar | fgrep Logger
     1545  2023-02-26 11:06   META-INF/versions/9/org/yaml/snakeyaml/internal/Logger$Level.class
     1365  2023-02-26 11:06   META-INF/versions/9/org/yaml/snakeyaml/internal/Logger.class
     1446  2023-02-26 11:06   org/yaml/snakeyaml/internal/Logger$Level.class
     1264  2023-02-26 11:06   org/yaml/snakeyaml/internal/Logger.class
{code}
When I use the maven-shade-plugin 3.4.1 (latest at the time of writing) to shade this dependency in my project and relocate (!) it to a different package the final jar contains this:
{code:java}
     1678  2023-02-26 11:06   META-INF/versions/9/org/yaml/snakeyaml/internal/Logger$Level.class
     1484  2023-02-26 11:06   META-INF/versions/9/org/yaml/snakeyaml/internal/Logger.class
     1579  2023-02-26 11:06   nl/basjes/shaded/org/yaml/snakeyaml/internal/Logger$Level.class
     1383  2023-02-26 11:06   nl/basjes/shaded/org/yaml/snakeyaml/internal/Logger.class
{code}
Note that the *standard* variants have been shaded correctly and the *java 9* variants have not been relocated at all.
