Unable to use workflow using osworkflow.jar in jira 8.18.0

Question

We have developed a plugin in jira and We are using osworkflow to define our own custom workflow. Our plugin works within jira and when i try to initialize workflow, We are getting this error in jira.log

Caesium-1-3 ERROR ServiceRunner
[c.a.jira.workflow.DefaultOSWorkflowConfigurator] Rejecting usage of unsafe workflow function/class: com.service.workflow.condition.PermissionCondition. You can enable usage of this class by adding com.atlassian.jira.security.LegacyJiraTypeResolver.WARN_ONLY.enabled dark feature flag to Jira. Do it only if you are sure its known and secure case. It will make Jira vulnerablefor potential attacks.

and below exception is printed

[INFO] [talledLocalContainer] com.opensymphony.workflow.WorkflowException: Could not load condition [INFO] [talledLocalContainer] at com.opensymphony.workflow.AbstractWorkflow.passesCondition(AbstractWorkflow.java:1045) [INFO] [talledLocalContainer] at com.opensymphony.workflow.AbstractWorkflow.passesConditions(AbstractWorkflow.java:1083) [INFO] [talledLocalContainer] at com.opensymphony.workflow.AbstractWorkflow.passesConditions(AbstractWorkflow.java:1107) [INFO] [talledLocalContainer] at com.opensymphony.workflow.AbstractWorkflow.canInitialize(AbstractWorkflow.java:862) [INFO] [talledLocalContainer] at com.opensymphony.workflow.AbstractWorkflow.initialize(AbstractWorkflow.java:598)

Answer 1

So you use osworkflow outside Jira to generate a new workflow.xml file. And then import it into Jira? Seems odd not doing that inside Jira, but ok. I think I would start by exporting the XML of a working Jira workflow and then make sure that your generated workflow.xml looks like the one you know works
