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>

这里列出的解决方案可能提供一个指针。

清单主属性的签名文件摘要无效

底线:

最好把官方的罐子保存为 只是将其作为依赖项添加到您的manifest文件中 应用程序jar文件。

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

对于使用kotlin脚本(kts)作为构建脚本的人:

task("fatJar", type = Jar::class) {
baseName = "${project.name}-fat"
manifest {
    attributes["Implementation-Title"] = "Watcher Jar File"
    attributes["Implementation-Version"] = version
    attributes["Main-Class"] = "MainKt"
}
from(configurations.runtimeClasspath.get().map { if (it.isDirectory) it else zipTree(it) }) {
    exclude(listOf("META-INF/*.RSA", "META-INF/*.SF", "META-INF/*.DSA"))
}
with(tasks.jar.get() as CopySpec)

}

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。
