How to properly start a script generated by gradle using upstart?

I'm trying to deploy an Java app onto VPS. I'm using Gradle build system with 'application' plugin. I want the app to start up with the server.

During deployment process I run ./gradlew install to prepare run scripts. When ran directly, they work properly.

I used http://www.whiteboardcoder.com/2014/02/ubuntu-upstart-job-with-java-jar.html as a base for upstart configuration:

description "the test server"
start on runlevel [2345]
stop on runlevel [!2345]

expect fork

script
   cd /opt/testserver/
   exec ./build/install/testserver/bin/testserver
end script

But the PID reported by upstart after running start testserver is different then the one found using ps. My guess is that the reason for that is the last line of generated script:

exec "$JAVACMD" "${JVM_OPTS[@]}" -classpath "$CLASSPATH" mypackage.TestServer"$@"

As a result Upstart is not able to stop the app. Is there a way to make upstart see the right PID?

Solution

  • Well it looks like there is no forking going on here, so you should try removing the expect fork bit.
