Shadow Version

4.0.3

Expected Behavior

If any dependencies included have the Multi-Release flag set to true in MANIFEST.MF, the shadow jar should include this entry.

Actual Behavior

Currently a manual process. Requires knowledge of all dependencies and manually adding required entry to MANIFEST.MF.

Background

Current versions of Java allow for multi-release jars to be created. However, in order for it to work, Multi-Release: true needs to be present in the manifest. One popular example of a multi-release jar is the Log4J API (org.apache.logging.log4j:log4j-api). See this stack overflow question for more details. It would be nice if the shadow plugin would automate this process.
