Manifest主属性w/Jetty和Maven Shade插件的签名文件摘要无效

Question

我看到了其他一些SO问答；关于这个话题，但到目前为止，没有一个解决方案对我有效：

• "无效的签名文件"；尝试运行.jar时
• 线程中的异常"；主"；java.lang.SecurityException：Manifest主属性的签名文件摘要无效
• JavaFX项目的有效JAR签名

我们将Jetty与Maven Shade插件一起用于开源应用程序：

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

我们在构建中开始出现以下错误：

$ java -jar onebusaway-gtfs-realtime-from-nextbus-cli.jar

Answer 1

看起来这是Jetty:中的一个错误

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

来自上述错误报告：

jetty-7.6.1.v20120215所依赖的javax.servlet-2.5.0.v201103041518.jar包存在问题：在javax.servlet jar的META-INF目录中，可以找到文件ECLIPSEF。RSA和ECLIPSEF。SF。

如果你用maven生成一个使用jetty的jar，你会在最后一个jar的META-INF目录中得到这两个文件，如果你运行它，你会得到一个异常：

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

修复方法是从生成的jar中排除2个有问题的文件。

不需要的文件可以通过maven shade插件添加到POM:中来排除

<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>

添加：

<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>

到我们的pom.xml为我们工作。
