Unable to run java jar command on target machine in Ansible

Question

I am trying to run the following command:

java -jar jar-from-application.jar --file myown.properties

Couple of problems I faced earlier while trying to run this on target machine. Tomcat needs to be running and a war file needs to be deployed completely before I run the above command. This is what I did to insure that pre conditions are met. For Tomcat:

nohup startup.sh

and then check for deployed file bu using curl to check for status 200:

- name: Check if URL is available
  shell: curl --head --silent http://target-mchine:8080/restoftheurl
  register: result
  until: result.stdout.find("200 OK") != -1
  retries: 12
  delay: 10

It does above two steps correctly but when the next task is to run the

java -jar jar-from-application.jar --file myown.properties

it for some reason says that it cannot read the properties file. However, if I run the same jar command on the remote machine locally, then it works perfectly. I even added some wait time after successful execution of curl command, just in case, but it doesn't make any difference. I tried doing the following too:

nohup java -jar jar-from-application.jar --file myown.properties

as it was suggested online but that didn't make any difference either. Any suggestions will be appreciated. Thank You.

确保使用命令模块的chdir参数在命令中为属性文件设置了正确的path ，或者在命令中设置了完整路径。
