Jenkins SSH Credentials - Algorithm Negotiation Fail

[Daniel Crowder]

After resolving this issue with NetBeans, I am still encountering an issue with establishing a ssh connection to a server via Jenkins and the SSH Credential plugin.

I am curious to know if anyone has encountered this issue recently and if so what solution worked for you.

Thanks,

Issue resolved....never fails when you get to that point of giving up do you find the solution.

So for anyone who comes across the issue with the Publish Over SSH Plugin where you can no longer create a successful connection to your server(s) try doing the following:

Grabbing a copy of the plugin from GitHub and editing the pom.xml file to use the 1.53 version of jsch oppose to 1.45.

https://github.com/jenkinsci/publish-over-ssh-plugin

Once you've made the update to the pom.xml file run mvn clean install -DskipTests (this is a Maven command) to generate a {plugin_name}.hpi which will be located in the newly created directory target/. From the jenkins ui go to manage plugins and click the advance tab and upload the new hpi file. This should resolve the issue.

The other step that may be necessary is downloading and installing the Java Cryptography Extension for your specific version of Java. (This update alone resolved the same connectivity issue with Netbeans).

Hope this helps anyone who runs into this issue.
