The problem
Using JDeveloper 12.1.3, I had created a dummy BPMN Process with just a User Task bound to a human task. For this task I had also auto-generated an input form. Deploying the task form went fine, but when trying to deploy the BPMN process I got the following error:
[08:30:27 AM] Deployment cancelled.
[08:30:27 AM] Taskflow deployment failed to deploy to server. Remote deployment failed
[08:30:27 AM] Deployment cancelled.
[08:30:27 AM] ---- Deployment incomplete ----.
[08:30:27 AM] Remote deployment failed (oracle.jdevimpl.deploy.common.Jsr88RemoteDeployer)
The cause
After trying various things, I discovered the problem was my proxy settings in Oracle® JDeveloper.
The solution
Tools -> Preferences -> Web Browser and Proxy -> Proxy Settings, and then I set it to No Proxy.
Now I could deploy the process without any errors.
I assume it would also have worked if I had set it to Manual Proxy Settings, and then added my hostname to the exception list.
