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/

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。

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。

比较新jar和旧jar中的META-INF文件夹(在添加新库之前)。有可能会有新的文件。如果是，可以删除。这应该会有所帮助。 问候, 999米甲

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>
