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>

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)

}

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>

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'
    }
}
