Multiple process archives with SpringBoot

Camunda 7 Topics Discussion & Questions

Hi folks,

I am using Camunda 7.11 with the camunda-spring-boot-starter 3.3.3 and I try to achieve tenant specific deployments, using process archives in the processes-xml, like this:

<process-application
        xmlns="http://www.camunda.org/schema/1.0/ProcessApplication"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <process-archive name="All">
        <process-engine>default</process-engine>
        <properties>
            <property name="isDeleteUponUndeploy">false</property>
            <property name="isScanForProcessDefinitions">true</property>
            <property name="resourceRootPath">pa:tenants/all</property>
        </properties>
    </process-archive>
    <process-archive name="One" tenantId="1">
        <process-engine>default</process-engine>
        <properties>
            <property name="isDeleteUponUndeploy">false</property>
            <property name="isScanForProcessDefinitions">true</property>
            <property name="resourceRootPath">pa:tenants/one</property>
        </properties>
    </process-archive>
</process-application>

My resources folder structure looks like this:

resources
  META-INF
    processes-xml
  tenants
    all
      some-process.bpmn
    one
      another-process.bpmn

Running the app with gradle bootRun works fine, but running it with java -jar does not work, because the structure of the jar is different after SpringBoot has repackaged it:

BOOT-INF
  classes
    META-INF
      processes.xml
    tenants
      all
        some-process.bpmn
      one
        another-process.bpmn

When Camunda is handling the archive in ClassPathProcessApplicationScanner#handleArchive, it comes across the BPMN files, but their file path e.g. BOOT-INF/classes/tenants/one is not below the paResourceRootPath, which is e.g. tenants/one, even though I configured it as being relative to the process archive using the pa: prefix.

Of course, I can set the path to BOOT-INF/classes/... in the processes.xml, but running with Gradle will not work any more. How can I achieve both?

Cheers,
Stefan

It’s been quite a while, but I am answering my own question now: Multi-tenant deployments with Camunda BPM and SpringBoot | by Stefan Zilske | Holisticon Consultants | Jan, 2022 | Medium

tl;dr: it seems not to be possible with Camunda’s auto-depioyment, so writing a custom deployment solved the issue for us.
