I was trying to create an uber jar with maven and ran in to this problem and I was able to solve the issue as follows.

Here is how I configured the shade plugin to include twitter4j to my uber jar.

<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>2.4.2</version> <executions>     <execution>         <phase>package</phase>         <goals>             <goal>shade</goal>         </goals>         <configuration>              <filters>                 <filter>                     <artifact>spark-streaming-twitter_2.10:spark-streaming-twitter_2.10</artifact>                     <includes>                         <include>**</include>                     </includes>                 </filter>                 <filter>                     <artifact>twitter4j-stream:twitter4j-stream</artifact>                     <includes>                         <include>**</include>                     </includes>                 </filter>                 <filter>                     <artifact>*:*</artifact>                     <excludes>                         <exclude>META-INF/*.SF</exclude>                         <exclude>META-INF/*.DSA</exclude>                         <exclude>META-INF/*.RSA</exclude>                     </excludes>                 </filter>             </filters>         </configuration>     </execution> </executions> </plugin> 

Hope this helps.

After surfing the internet for hours, and still unable to find the solution, I stumbled upon this command which SOLVED my problem:

zip -d yourjar.jar 'META-INF/.SF' 'META-INF/.RSA' 'META-INF/*SF' 

This command rips off the signature files for the previous jars, and then once you sign it you'l find no error.

回答3:

I think i got the solution for my own question, addition of tags mentioned below to the pom.xml solves the issue:

<excludes>     <exclude>META-INF/*.SF</exclude>     <exclude>META-INF/*.DSA</exclude>     <exclude>META-INF/*.RSA</exclude>     <exclude>junit:junit</exclude>     <exclude>org.apache.maven:lib:tests</exclude> </excludes>

I was having similar issues, I added Bounty Castle dependency that was causing this error. Just removed it and after that it worked okay.

回答5:

The following Stackexchange question and answer worked for me. It uses a filter instead of and artifactSet exclude. I have tried the solutions in the above answer and it didn't work.
