org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.atlassian.migration.app.tracker.CloudMigrationAccessor': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.atlassian.migration.app.tracker.CloudMigrationAccessor]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: com/atlassian/migration/app/BaseAppCloudMigrationListenerCause
The Scheduler App has a dependency to another plugin Jira Cloud Migration Assistant. Due to this, if Jira Cloud Migration Assistant cannot be started properly, it will cascade the problem to the other plugin The Scheduler since this last one has a dependency expected from the other.
