How to trigger a hudson job by another job which is in a different hudson

Question

I have job A in Hudson A and Job B in Hudson B. I want to trigger job A by Job B.

Answer 1

In your job B configuration, check the Trigger builds remotely (e.g., from scripts) checkbox and provide a token.

The help text there shows you the URL you can call to trigger a build from remote scripts (e.g. from a shell script in Hudson job A).

However, that would trigger job B no matter what the result of job A is.
Morechilli's answer is probably the best solution.

Answer 2

I haven't used Hudson but I would guess your simplest approach would be to use the URL trigger:

I think there is a latest build url that could be used for this.
