Neo4j: making one JAR package from app with Neo4j libraries (duplication 'META-INF/...' files)

Question

I understand, the source of this issue. I've saw the topic here.

And here is some possible solution.

But the last one doesn't work for me.

Have the problem with making one jar package (with Maven) of my app with Neo4j libraries within. When I use this jar in another project - everything works fine, but when I try to launch web-interface - I get the above mentioned issue. My app throws Exception with next lines:

01:19:49.727 [main]       INFO o.e.jetty.server.ServerConnector - Started ServerConnector@7e75bf2d{HTTP/1.1}{0.0.0.0:7474}

SEVERE: A message body writer for Java class java.lang.String, and Java type class java.lang.String, and MIME media type application/json was not found

And the data in in web-interface doesn't displayed, as expected.

It is really important to package everything into one JAR for next app distribution.

I've resolved my issue. In my case in addition to this 'shade-plugin' configuration - I add next lines. Add now everything works fine:

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

I hop this helps someone...
