我的java程序被打包在一个jar文件中,并使用了一个外部jar库,bouncy castle。我的代码编译良好,但运行jar会导致以下错误:

java.lang.SecurityException: Manifest主属性的签名文件摘要无效

我在谷歌上搜索了一个多小时,想要找到一个解释,但几乎没有什么价值。如果有人看到这个错误之前,可以提供一些帮助,我将不胜感激。

对于那些使用gradle并试图创建和使用fat jar的人来说,下面的语法可能会有所帮助。

jar {
    doFirst {
        from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } } 
    }
    exclude 'META-INF/*.RSA', 'META-INF/*.SF','META-INF/*.DSA' 
}

对于那些对已接受的解决方案有问题的人,有另一种方法可以使用dontincleresourcetransformer从阴影jar中排除资源:

https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#DontIncludeResourceTransformer

          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.DontIncludeResourceTransformer">
                <resource>BC1024KE.DSA</resource>
            </transformer>
          </transformers>

从Shade 3.0开始,这个转换器接受一个资源列表。在此之前,您只需要使用多个转换器,每个转换器具有一个资源。

假设您使用ant构建jar文件,您可以指示ant去掉META-INF目录。这是我的蚂蚁目标的简化版本:

<jar destfile="app.jar" basedir="${classes.dir}">
    <zipfileset excludes="META-INF/**/*" src="${lib.dir}/bcprov-jdk16-145.jar"></zipfileset>
    <manifest>
        <attribute name="Main-Class" value="app.Main"/>
    </manifest>
</jar>

我也遇到过同样的问题,经过参考,它的工作原理如下:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>3.2.1</version>
    <configuration>
        <createDependencyReducedPom>false</createDependencyReducedPom>
    </configuration>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <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>
        </execution>
    </executions>
</plugin>

I've recently started using IntelliJ on my projects. However, some of my colleagues still use Eclipse on the same projects. Today, I've got the very same error after executing the jar-file created by my IntelliJ. While all the solutions in here talking about almost the same thing, none of them worked for me easily (possibly because I don't use ANT, maven build gave me other errors which referred me to http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException, and also I couldn't figure out what are the signed jars by myself!)

最后,这帮助了我

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

猜猜我的jar文件里删除了什么!

deleting: META-INF/ECLIPSE_.SF 
deleting: META-INF/ECLIPSE_.RSA

这个问题似乎与一些与eclipse相关的文件有关。

有可能是两个不同的签名者搞砸了java思维。

尝试从jar中删除META-INF文件夹,再次添加清单和签名jar,它帮助了我:http://jehy.ru/articles/2013/12/13/invalid-signature-file-digest-for-manifest-main-attributes/
