How to add camunda resources autodeploy in graalVM?

[nklimkin]

Hello! I want to try to start my micronaut application with camunda in graalVM, but when I start my app there is no messages in log about deploy bpmn and dmn files from resources and there is no data in camunda tables in database. I add paths to it in my resource-config.json and choose right camunda.locations. Do you have some ideas how it can be fix?

Hi @nklimkin ,

thanks for trying the integration and creating this issue.

This project does currently not fully support GraalVM (we should a FAQ with the known issues and workarounds).

One issue is the missing auto-deployment you experienced.

Have you tried using repositoryService.createDeployment() manually with your bpmn file which you call in an @EventListener which is registered to ServerStartupEvent?

You don't say so, but I guess its working for you without GraalVM, right?

I assume that you will run into more issues - some are documented here: #9

However, if you implement an external worker it will work and your external worker will start in milliseconds with GraalVM:

Yes, I have tried to create custom deploy with repositoryService and it work correct without GraalVM but if I do the same with GraalVM there are exceptions that there are no enough xsd files in resources to parse my bpmn files.
Thank you for advice to try external task and link to example of start application in GraalVM, I will try it

Hi @nklimkin ,

which exception did you get?

Did you manage to get the external task worker running with GraalVM?

Hi, I have gotten exceptions that, where are no xsd files to parse bpmn and dmn files, after I add these xsds to resource config for graalVM, everything start be okey, and there are no another exceptions.

Hi @nklimkin ,
thanks for your feedback. I'm glad you got it working. How are your startup times?

Would you like to create a pull request to document how to get GraalVM working?
It could be documented here: https://github.com/camunda-community-hub/micronaut-camunda-platform-7#advanced-topics

And you could use this as a template:
