Bpmn file update does not work after grails with camunda plugin deployed to tomcat

  • Windows 10 Enterprise x64 English
  • JDK 8u131
  • Grails: 2.5.6
  • Grails Plugin: org.camunda.bpm:camunda-engine:7.7.0
  • Apache Tomcat 8.5.16
  • We deploy the war file built by Grails to tomcat\webapps directory.
  • We use repositoryService.createProcessDefinitionQuery().latestVersion() to get the process definitons.
  • We updated the tomcat\webapps\[war-file-name]\WEB-INF\classes\[package-name]\sample.bpmn file.
  • We check the process definitions, nothing happened.
  • We even try to delete the bpmn file, the corresponding process is still there.
  • We did exactly the same before, the bpmn file updated as we expected.
  • Now we have no idea why it is not working.

Any help would be appreciated.


Any help, please?

Looks like this does not happen every time. But when it happens, we need to know how to fix it.


Hi @GhostFox,

Although I am not familiar with the Camunda Grails plugin, any kind of logs showing the deployment could help to track down the problem.



We just found out what happened.

Just simple.

  • One of our developer forgot to execute the sql update script on the camunda database.
  • He happened to ignore the error message that complained on the database schema.

That’s why the bpmn file update did not reflect the process update.

Hope it helps.
