Invalid signature file digest for Manifest main attributes

[Venkata Suresh Kumar Pamidipati <su...@oracle.com>]

Hi,

I have included multiple dependency jars in pom.xml and I am trying to build distribution jar using assembly:assembly goal. The command "mvn assembly:assembly" resulted in the below error. 

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4:assembly (default-cli) on project my-plugin: Execution default-cli of goal org.apache.maven.plugins:maven-assembly-plugin:2.4:assembly failed: Invalid signature file digest for Manifest main attributes -> [Help 1]

Two of the dependency jars when present together was causing this issue. I tried commenting one of them and mvn assembly:assembly command worked fine. To make it work with both the jars present together, I tried by adding excludes in dependency, assembly and even shade plugin configuration in pom.xml to exclude MANIFEST files of one of those two jars as shown below, but still the same error exists.

            <configuration>
              <filters>
                <filter>
                  <artifact>MyJar1:MyJar1</artifact>
                  <excludes>
                    <exclude>META-INF/*.SF</exclude>
                    <exclude>META-INF/*.DSA</exclude>
                    <exclude>META-INF/*.RSA</exclude>
                  </excludes>
                </filter>
              </filters>
            </configuration>

Please let me know how to resolve this error. I am not sure if the exclude statements were being ignored or I am missing some thing here. Any information on this will be really helpful.

Thanks & Regards,
Suresh
