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

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。

我有同样的问题，在gradle创建一个胖罐;更新构建。Gradle文件排除行纠正了这个问题。

jar {
    from {
        configurations.compile.collect {
            it.isDirectory() ? it : zipTree(it)
        }
    }
    exclude 'META-INF/*.RSA', 'META-INF/*.SF','META-INF/*.DSA'
    manifest {
        attributes 'Main-Class': 'com.test.Main'
    }
}

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。
