Question

在Eclipse中测试SSHJ，一切看起来都不错。但是，当我使用Maven shade插件打包SSHJ时，我收到以下错误：

Exception in thread "main" net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods
at net.schmizz.sshj.SSHClient.auth(SSHClient.java:217)
at net.schmizz.sshj.SSHClient.authPublickey(SSHClient.java:316)

at no.f12.SshService.serviceCommand(SshService.java:22)
at no.f12.App.main(App.java:29)

添加

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

将错误消息更改为：

Exception in thread "main" net.schmizz.sshj.transport.TransportException: Unable to reach a settlement: [] and [aes128-ctr, aes192-ctr, aes256-ctr, arcfour256, arcfour128, aes128-gcm@openssh.com, aes256-gcm@openssh.com, aes128-cbc, 3des-cbc, blowfish-cbc, cast128-cbc, aes192-cbc, aes256-cbc, arcfour, rijndael-cbc@lysator.liu.se]

知道怎么解决这个问题吗？

为什么我想使用阴影的一些背景...我试图达到一个点，Java的使用和小工具的分配很简单。所以我用这个创建一个真正可执行的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和添加到用户的路径。有点像Go有一个包含所有依赖项的二进制文件。

Answer 1

我遇到了这个问题。我终于放弃了试图把所有东西放在一个大的＆＃34; uberjar＆＃34;。

相反，我使用maven-assembly-plugin组装了所有的jar，然后提取并将它们添加到类路径中以便执行，例如，＆＃39; java -cp all-needed-libs / * com.company.MainClass＆＃39;。

Answer 2

另一种可行的方法是将bouncycastle添加到JRE扩展库。

e.g put＆＃39; bcprov-jdk15on-1.49.jar＆＃39;在文件夹＆＃39; $ JAVA_HOME / jre / lib / ext /＆＃39;在主持人身上。

你必须签署jar，这是Javax.security所要求的。我遇到了类似的问题，我的测试中有堆栈跟踪：
