我也遇到过类似的问题。原因是我使用的JDK的JRE与Windows系统中的默认JRE不同。

使用正确的java.exe解决了我的问题。

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
}

Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes at sun.security.util.SignatureFileVerifier.processImpl(SignatureFileVerifier.java:314) at sun.security.util.SignatureFileVerifier.process(SignatureFileVerifier.java:268) at java.util.jar.JarVerifier.processEntry(JarVerifier.java:316) at java.util.jar.JarVerifier.update(JarVerifier.java:228) at java.util.jar.JarFile.initializeVerifier(JarFile.java:383) at java.util.jar.JarFile.getInputStream(JarFile.java:450) at sun.misc.URLClassPath$JarLoader$2.getInputStream(URLClassPath.java:977) at sun.misc.Resource.cachedInputStream(Resource.java:77) at sun.misc.Resource.getByteBuffer(Resource.java:160) at java.net.URLClassLoader.defineClass(URLClassLoader.java:454) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:368) at java.net.URLClassLoader$1.run(URLClassLoader.java:362) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:361) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:495)

帮助我的(IntelliJ IDEA 2016.3): 文件->项目结构-> Artifacts ->添加JAR ->选择主类->选择“通过manifest复制到输出目录和链接”->确定->应用->构建->构建Artifacts…- >构建

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>

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' 
}
