对于那些在尝试使用maven-shade-plugin创建阴影超级jar时遇到此错误的人，解决方案是通过在插件配置中添加以下行来排除清单签名文件:

<configuration>
    <filters>
        <filter>
            <artifact>*:*</artifact>
            <excludes>
                <exclude>META-INF/*.SF</exclude>
                <exclude>META-INF/*.DSA</exclude>
                <exclude>META-INF/*.RSA</exclude>
            </excludes>
        </filter>
    </filters>
    <!-- Additional configuration. -->
</configuration>

您可以使用Shadow生成一个jar。

Shadow是一个Gradle插件，用于将项目的依赖类和资源组合到一个输出Jar中。组合罐通常被称为fat-jar或super - Jar。

Modify build.gradle plugins { ... // ① Add the shadow plugin id "com.github.johnrengelman.shadow" version "5.2.0" } ... // ② Config the shadow jar, its name is baseName-1.0-classifier.jar shadowJar { archiveBaseName.set('baseName') archiveClassifier.set('classifier') archiveVersion.set('1.0') manifest { attributes 'Main-Class': 'Main' } } // ③ Disable the default jar task jar.enabled = false // ④ Execute the shadowJar task when compiling build.dependsOn(shadowJar) Execute the command gradle build, the jar file will be generated: <Project Directory>/build/libs/baseName-1.0-classifier.jar

如果您在尝试为Xamarin绑定JAR文件时遇到这种情况。Android绑定项目如下:

J2XA006:在反映清单主属性的com.your.class:无效签名文件摘要时引发了缺少类错误

只需使用Winzip打开JAR文件并删除meta-inf目录。重建-工作完成

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。

请使用以下命令

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

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>
