I am giving a try with the app42 PaaS solution from Shephertz, and especially its CustomCode feature to deploy Java server-side code.
I managed to correctly deploy one version of my server-side "CustomCode" jar (using "ant deploy" command, like in the provided sample).
The problem is that I can't undeploy it
- either from the "ant undeploy" command, cf. this error
(the html returned looking like this)
- or from the App42 management console (POST is successful but returns failure message)
Obviously, this prevents me to deploy a new version of this jar, cf. this error
It has been answered at our forum here. See this http://forum.shephertz.com/index.php/57/impossible-undeploy-customcode-therefore-impossible-version?show=57#q57
