我已经看过其他一些SO Q& As这个主题,但到目前为止,没有一个解决方案对我有用:

我们使用Jetty作为开源应用程序,以及Maven Shade插件:

我们开始在构建中收到以下错误:

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

1 个答案:

答案 0 :(得分:2)

看起来这是Jetty中的一个错误:

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

从上面的错误报告:

  

javax.servlet-2.5.0.v201103041518.jar包装有一个问题,其中jetty-7.6.1.v20120215依赖于:在javax.servlet jar的META-INF目录中找到文件ECLIPSEF.RSA和ECLIPSEF.SF。

     

如果你生成一个带有使用jetty的maven的jar,你可以在最后一个jar的META-INF目录中获得这两个文件,如果你运行它就会得到一个异常:

     

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个违规文件。

     

可以使用添加到POM的maven-shade-plugin排除不需要的文件:

<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>

...我们的pom.xml为我们工作。
