Spring Task in Spring Cloud Dataflow on PCF can't find java

i have a Spring Cloud Task fat jar that i have successfully deployed to SCDF running on PCF. i have created a definition for it and can therefore run it from the dashboard. fwiw it reads and writes from a database using Spring JDBC.

i'm trying to now set it up to run in a scheduled way and am having issues. i created a stream with a triggertask source and a task-launcher-local sink, and have configured the triggertask URI to point to the fat jar (via http, using a staticfile PCF pushed app).

the dashboard shows the two PCF apps (one for triggertask, one for task-local-launcher) both starting successfully, and it all runs, but the task fails every time with the error:

Caused by: java.io.IOException: Cannot run program "java" (in directory "/home/vcap/tmp/spring-cloud-dataflow-5903184636016162160/Task--582903409-1502669137014/Task--582903409"): error=2, No such file or directory

from what i can tell and surmise, the PCF app running the stream tries to fork and exec a java call, but since java is not in the path for PCF app containers i get the error

am i right? either way, how can i get the Spring Cloud Task (jar) to successfully run?

The stream definition is missing from the post. It is possible that you're using the tasklauncher-local sink, which is compatible only when using SCDF's local-server and it will fail with the attached error when running in CF. Please make sure you're using tasklauncher-cloudfoundry sink. This application was added in the latest release of app-starters.

As pointed in the previous SO thread, it is highly recommended that you use the latest release of app-starters (1.0.4 is at least 10 months old). The latest releases can be found at the project site.
