Camunda Project Template (Gradle)

Camunda 7 Topics Discussion & Questions
1

I created a modular project template for camunda.

This splits your project into 3 gradle modules:

  • Process Application (your process)
  • Package WAR (builds the tomcat war deployment)
  • Package Boot (Spring Boot embedded process engine)

We can also add more package modules later on, but you can deploy the same process as a spring boot standalone service, run it in memory for testing or deploy it into a tomcat application server.

I would be happy over some feedback.

Updated it for camunda 7.9 - now also contains a boot aio build for local testing (with webapps and rest api).

I was happy to find this template using Gradle - thanks for sharing.
However, it took me some time and research to make it running. All bootRun* Gradle tasks failed with an error like

C:\camunda-template>gradlew bootRunWithLocalDb

> Task :camunda-template-package-boot:bootRun FAILED
Fehler: Hauptklasse application.CamundaProcessApplication konnte nicht gefunden oder geladen werden
Ursache: java.lang.ClassNotFoundException: application.CamundaProcessApplication

FAILURE: Build failed with an exception.
...

May I suggest three fixes (patch):
