Invalid signature file digest for Manifest main attributes w/ Jetty and Maven Shade Plugin

问题

I've seen a few other SO Q&As on this topic, but so far none of the solutions have worked for me:

"Invalid signature file" when attempting to run a .jar
Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
Valid JAR signature for JavaFX projects

We're using Jetty for an open-source application, along with the Maven Shade Plugin:

https://github.com/OneBusAway/onebusaway-gtfs-realtime-from-nextbus-cli

We started getting the following error in builds:

$ java -jar onebusaway-gtfs-realtime-from-nextbus-cli.jar
Error: A JNI error has occurred, please check your installation and try again

Looks like this is a bug in Jetty:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=371954

From the above bug report:

There is an issue with javax.servlet-2.5.0.v201103041518.jar packaging on which jetty-7.6.1.v20120215 depends: in the META-INF directory of the javax.servlet jar are found files ECLIPSEF.RSA and ECLIPSEF.SF.

If you generate a jar with maven that uses jetty, you get those 2 files in the META-INF directory of the final jar, and if you run it you get an Exception:

java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

The fix is to exclude the 2 offending files from the generated jars.

The unwanted files can be excluded with the maven-shade-plugin adding to a POM:
<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-shade-plugin</artifactId>
 <version>1.4</version>
 <executions>
  <execution>
   <goals>
    <goal>shade</goal>
   </goals>
   <configuration>
     <filters>
    <filter>
          <artifact>org.eclipse.jetty.orbit:javax.servlet</artifact>
        <excludes>
          <exclude>META-INF/ECLIPSEF.RSA</exclude>
              <exclude>META-INF/ECLIPSEF.SF</exclude>
              <exclude>META-INF/eclipse.inf</exclude>
        </excludes>
        </filter>
       </filters>
    </configuration>
   </execution>
  </executions>
</plugin>

Adding the:

<filters>
    <filter>
        <artifact>org.eclipse.jetty.orbit:javax.servlet</artifact>
            <excludes>
                <exclude>META-INF/ECLIPSEF.RSA</exclude>
                <exclude>META-INF/ECLIPSEF.SF</exclude>
                <exclude>META-INF/eclipse.inf</exclude>
            </excludes>
    </filter>
</filters>

... to our pom.xml worked for us.
