Thanks for helping me and also for the detailed explanation about the
extraction of jar while pushing an app. But i could not get the run-task
command to work. It errors out for Incorrect usage : unknown flag 'c'.
This is odd. It looks like there might be an escaping issue with the
command you're setting. It's hard to tell. I don't think this is related
to the `-cp` in the command. That's most definitely required or the JVM
won't be able to find the JarLauncher class.

I am using switch --no-start while i push the app. Is it required to be
started ?
That should be fine. I was running my demo this way yesterday.

I also tried
'cf run-task my_app_name
'$PWD/.java-buildpack/open_jdk_jre/bin/java $PWD/.org.springframework.boot.loader.JarLauncher
arg0 arg1'`. without the -cp.
Any chance you could send a screenshot of the command you're running so we
can see it exactly?

It seems to run but the does not actually call the main class rather
results in error :

d container

I have no clue what this error is.
I think it's a problem with how the command is being run. I think it runs
`bash -c 'blah'` where `blah` is the command to execute in the container.
That's why it almost seems like there's an escaping issue with the
command. Can you include the output of `cf tasks` for your app? That
should also list the command that was run.


Other thing, I am trying to create a job for my app which is bound to
scheduler service. when i execute the command to create job like :
cf create-job my_app my_job command

i get an error that no requested resource was found and i must create an
instance of scheduler service in this space inspite of having a service for
scheduler in the same space.
