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。

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。

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>

一种策略包括使用ANT来简化从每个Jar文件中删除签名。它将采取下列步骤:

复制舱单。MF在临时文件中 从临时文件中删除Name和SHA条目 用临时清单创建一个临时Jar文件 移除临时舱单 将原始Jar文件与临时Jar文件交换

下面是一个ANT宏def做的工作:

<macrodef name="unsignjar" description="To unsign a specific Jar file">
    <attribute name="jarfile" 
        description="The jar file to unsign" />
    <sequential>
<!-- Copying to the temporary manifest file -->
        <copy toFile="@{jarFile}_MANIFEST.tmp">
            <resources>
                <zipentry zipfile="@{jarFile}" name="META-INF/MANIFEST.MF"/>
            </resources>
        </copy>
<!-- Removing the Name and SHA entries from the temporary file -->
        <replaceregexp file="@{jarFile}_MANIFEST.tmp" match="\nName:(.+?)\nSH" replace="SH" flags="gis" byline="false"/>
        <replaceregexp file="@{jarFile}_MANIFEST.tmp" match="SHA(.*)" replace="" flags="gis" byline="false"/>
<!-- Creating a temporary Jar file with the temporary manifest -->
        <jar jarfile="@{jarFile}.tmp"
            manifest="@{jarFile}_MANIFEST.tmp">
            <zipfileset src="@{jarFile}">
                <include name="**"/>
                <exclude name="META-INF/*.SF"/>
                <exclude name="META-INF/*.DSA"/>
                <exclude name="META-INF/*.RSA"/>
            </zipfileset>
        </jar>
<!-- Removing the temporary manifest -->
        <delete file="@{jarFile}_MANIFEST.tmp" />
<!-- Swapping the original Jar file with the temporary one -->
        <move file="@{jarFile}.tmp"
              tofile="@{jarFile}"
              overwrite="true" />
</sequential>

`

在ANT任务中可以这样调用定义:

<target name="unsignJar">
    <unsignjar jarFile="org.test.myjartounsign.jar" />
</target>

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' 
}
