Hi,  
May I ask for execute java program with ansible?  
I execute a java program (spring boot project, a jar package for java web site)  
ansible ofbiz1 -m shell -a “chdir=/opt/CassEC-OrderSupports nohup java -jar product.jar &”, it echo success ,but in fact,it do nothing! the java program is not been started!  
I’m very sure that I can execute nohup java -jar product.jar & in the machine directly, I can start the java program.

and I try use this command ,  
ansible ofbiz1 -m shell -a “chdir=/opt/CassEC-OrderSupports nohup /usr/java/jdk1.8.0\_74/java -jar product.jar &”,  
as I prefer the java direction, it work!

Can anybody tell me why? and how can I use java -jar direct with ansible?

I'd avoid nohup like the plague.

Why not just write a small upstart or systemd script and run your java  
app as a service: task?
