W-12272032

Known Issues

Known Issue Workaround ID

The Mule Secure Configuration Properties Extension module and Azure Key Vault Properties Provider share the same project structure, so they both export the com.mulesoft.modules.configuration.properties.api package. In Mule apps, this causes deployment failures which results in the DuplicateExportedPackageException: There are multiple artifacts exporting the same package error, because the Mule runtime classloader doesn’t allow two different extensions to export the same package.

This issue is fixed in Azure Key Vault Properties Provider 2.0.0 and later. To ensure successful deployment of your Mule apps, upgrade Azure Key Vault Properties Provider to version 2.0.0 or later.
