Description:
|
Once I upgraded to Jenkins 1.5, my slave agent ("mac-mini") could no longer connect. Here's an example session (I changed the hostname and credentials to protect the guilty):
$ java -jar ./slave.jar -jnlpCredentials myuser:mypassword -jnlpUrl https://ci.mydomain.com/jenkins/computer/mac-mini/slave-agent.jnlp -noCertificateCheck
Skipping HTTPS certificate checks altoghether. Note that this is not secure at all.

INFO: Hudson agent is running in headless mode.

I then used Charles Proxy to capture the HTTP traffic to see what was going on. I've attached a file of that capture, but the relevant problem is here:
<argument>-url</argument><argument>http://ci.mydomain.com/jenkins/</argument>
The problem is that the slave is being told to connect via HTTP, but (thanks to our proxy) it is only available via HTTPS. I checked my configuration and it is correct. I believe the issue is caused by this change on January 15th: https://github.com/jenkinsci/jenkins/commit/460e508155187918e8c0f4fd0bb66a99cfe78527#L0R1877 . The protocol of the request as far as Jenkins knows is HTTP. However the client needs to use the HTTPS protocol I configured for our root URL.
