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。

如果你正在使用gradle，这里有一个完整的farJar任务:

version = '1.0'
//create a single Jar with all dependencies
task fatJar(type: Jar) {
    manifest {
        attributes 'Implementation-Title': 'Gradle Jar File Example',  
            'Implementation-Version': version,
            'Main-Class': 'com.example.main'
    }
    baseName = project.name + '-all'
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    exclude 'META-INF/*.RSA', 'META-INF/*.SF','META-INF/*.DSA' 
    with jar
}

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)

}

如果您正在寻找一个不解包或修改原始库，而是使用一个特殊的JAR类加载器的Fat JAR解决方案，请参阅我这里的项目。

免责声明:代码不是我写的，只是打包并发布在Maven Central上，并在我的阅读中描述如何使用它。

我个人使用它来创建包含BouncyCastle依赖的可运行的优jar。也许它对你也有用。

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。
