我的java程序被打包在一个jar文件中,并使用了一个外部jar库,bouncy castle。我的代码编译良好,但运行jar会导致以下错误:
java.lang.SecurityException: Manifest主属性的签名文件摘要无效
我在谷歌上搜索了一个多小时,想要找到一个解释,但几乎没有什么价值。如果有人看到这个错误之前,可以提供一些帮助,我将不胜感激。

我也遇到过同样的问题,经过参考,它的工作原理如下:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.2.1</version>
<configuration>
<createDependencyReducedPom>false</createDependencyReducedPom>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
</configuration>
</execution>
</executions>
</plugin>
其他回答
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/
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
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。
