SSHJ和Maven shade插件
SSHJ和Maven shade插件
提问于 2013-11-06 23:14:24
在Eclipse中测试SSHJ，一切看起来都很好。但是当我使用Maven shade插件来打包SSHJ时，我得到了以下错误：
Exception in thread "main" net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());将错误消息更改为：

关于我为什么要使用阴影的一些背景知识...我正试图达到这样一种程度，即Java的使用和小工具的分发是非常简单的。所以我使用以下命令创建了一个真正可执行的jar：https://github.com/brianm/really-executable-jars-maven-plugin。这使我能够创建一个可执行文件来分发并添加到用户的路径中。有点像Go有一个包含所有依赖项的二进制文件。

我就遇到了这个问题。我最终放弃了把所有东西都放在一个大的"uberjar“中的尝试。
相反，我使用maven-assembly plugin组装了所有jars，然后提取它们并将它们添加到类路径中以便执行，例如'java -cp all -needed libs/* com.company.MainClass‘。

另一种可行的方法是将bouncycastle添加到JRE扩展库中。
例如，将'bcprov-jdk15on-1.49.jar‘放在主机上的文件夹'$JAVA_HOME/jre/lib/ext/’中。

你必须在jar上签名，这是Javax.security要求的。我遇到了类似的问题，并且我的测试中有堆栈跟踪：
