Description:
|
We've got an old mac slave. After a recent upgrade of Jenkins I was unable to start a slave on this slave. It seems like the Jenkins slave is trying to load an incompatible class using the 1.5 jre.
[07/17/13 15:16:33] [SSH] Checking java version of java
[07/17/13 15:16:33] [SSH] java -version returned 1.5.0_13.
[07/17/13 15:16:33] [SSH] Starting sftp client.
[07/17/13 15:16:33] [SSH] Copying latest slave.jar...
[07/17/13 15:16:33] [SSH] Copied 326,561 bytes.
Expanded the channel window size to 4MB
[07/17/13 15:16:33] [SSH] Starting slave process: cd '/hudson' && java -jar slave.jar
<===[JENKINS REMOTING CAPACITY]===>channel started
