Pregunta 163

Pregunta
Why must a Mule application's deployable archive package all its dependencies in order to be deployed to CloudHub?
Respuesta
  • The online logging service requires access to ALL project dependencies to log the appropriate Java classes used in the Mule application
  • CloudHub workers CANNOT download ALL possible project dependencies a pro-ject may contain
  • CloudHub workers needs to compare the current dependencies with the LATEST project dependencies from the MuleSoft repository
  • MuleSoft support requires access to ALL project dependencies for future online troubleshooting
