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

             Summary: maven-jar-plugin sometimes doesn't add MANIFEST.MF as 1st or 2nd entry
                 Key: MNG-8266
                 URL: https://issues.apache.org/jira/browse/MNG-8266
             Project: Maven
          Issue Type: Improvement
          Components: build/consumer
            Reporter: Attila Kelemen


In certain situations (not sure what is the exact condition required), the Maven jar plugin doesn't add the _MANIFEST.MF_ as the 1st or 2nd entry. This can be a problem (even though technically the spec doesn't have such a requirement), because such a jar file cannot be read with the core JDK class {{JarInputStream}}.

A project this can be reproduced with is JDBI. See the [https://github.com/jdbi/jdbi/issues/2698] for details.
