It seems to me that there is more than one cause of this problem.
I have done the following: 1. upgraded cf CLI from 6.12 to 6.13 2.cf set-health-check MY_APP_NAME none 3. set <healthCheckTimeout>180</healthCheckTimeout> (pom.xml) 4. removed env variables in order to allow Maven to set them again
Still no luck.
However, I have read that there is intensive development of Maven client plugin 2.x happening now. I will give it a try as soon as first release is available.
