I'm trying to re-establish connectivity to an SSH slave that used to work
when I was running a much older version of Jenkins. Currently I'm using
v2.65. What I'm seeing (somewhat trimmed) in the log is the following:
[06/13/17 20:04:05] [SSH] Checking java version of java
[06/13/17 20:04:05] [SSH] java -version returned 1.7.0_75.
[06/13/17 20:04:05] [SSH] Starting sftp client.
[06/13/17 20:04:05] [SSH] Copying latest slave.jar...
[06/13/17 20:04:05] [SSH] Copied 719,269 bytes.
Expanded the channel window size to 4MB
[06/13/17 20:04:05] [SSH] Starting slave process: cd
"/data/jenkins-slave" && java -jar slave.jar
<===[JENKINS REMOTING CAPACITY]===>channel started
Slave JVM has not reported exit code. Is it still running?
[06/13/17 20:04:09] Launch failed - cleaning up connection
[06/13/17 20:04:09] [SSH] Connection closed.
