我的java程序打包在一个jar文件中,并使用外部jar库,bouncy castle.我的代码编译得很好,但是运行jar会导致以下错误:

线程"main"中的异常java.lang.SecurityException:Manifest主要属性的签名文件摘要无效

我用谷歌搜索了一个多小时寻找解释,发现很少有价值.如果有人以前看过这个错误并且可以提供一些帮助,我将不得不承担责任.

我的项目有不同的模块.

• 每个模块都有一个pom.xml,用于指定jar包装.
• 每个pom指的是共同的父母.
• 在父模块中还有一个包含所有模块的pom.xml.

当我尝试使用父模块的pom.xml打包时,它显示错误 - "打包jar无效聚合器项目需要pom作为打包".

如何从maven制作应用程序的可执行jar？

我正在尝试运行我的项目的jar文件.我正在研究intelliJ并使用工件来生成jar文件.但每次我试图运行我的jar文件时它给我异常.

将Bouncy Castle提供程序集成到Java程序中的最佳方法是什么？我知道我可以通过以下方式以编程方式添加它:

import org.bouncycastle.jce.provider.BouncyCastleProvider;
...
Security.addProvider(new BouncyCastleProvider());

或者我可以将它添加到我的机器上的JRE路径中.

什么是最好的选择？

我正在使用maven shade插件为我的项目生成一个合并jar.jar是按预期生成的,当我尝试使用jar并运行它时,我得到了一个

java.lang.SecurityException:Manifest主要属性错误的签名文件摘要无效.

我搜索了上面的错误消息,许多人建议从META-INF目录中排除清单签名.因此,我已经包含了从目录中排除这些文件的步骤[我看到两个文件的名称JARSIGN_.RSA和JARSIGN_.SF],但由于一些奇怪的原因,maven shade插件无法从META-INF目录中排除这些文件.谁能解释一下我可能做错了什么？我的pom.xml在下面,我用来生成jar的命令是:

mvn clean package shade:shade
