Flowable 7.0.0 is not autodeploying BPMNs

I am trying to upgrade to Spring Boot 3.1.3 and Java 17 and Flowable 7.0.0. When I build the application and look in the target folder I don’t see the BPMN under /classes. The BPMN is located under src/main/resources/processes

In the logs I see this:

o.f.s.b.ProcessEngineAutoConfiguration : No deployment resources were found for autodeployment

I have also tried to deploy it manually:

@Autowired
private ProcessEngine processEngine;

var repositoryService = processEngine.getRepositoryService();
String nameWithExt = "processes/" + xmlName + ".bpmn20.xml";
Deployment deployment = repositoryService.createDeployment().addClasspathResource(nameWithExt).deploy();

LOGs:

Solution

  • As mentioned here in the flowable docs, https://www.flowable.com/open-source/docs/bpmn/ch05a-Spring-Boot

    Any BPMN 2.0 process definitions in the processes folder will be automatically deployed.

    Your problem seems to be classpath related. You could also instruct flowable to use a folder for autodeployment by using these properties in your application.properties file.

    flowable.process-definition-location-prefix=classpath*:/processes/
flowable.process-definition-location-suffixes=**.bpmn20.xml,**.bpmn

    You can learn more about these properties here. https://www.flowable.com/open-source/docs/bpmn/ch05a-Spring-Boot#flowable-application-properties
