I discovered that in the UPM the App installation via URL breaks on OBR files:
Could not install the file MYFILE. Check that the file is valid.
JAR files work fine.
Is this intended or a bug? Since the file upload works for OBRs I would consider it a bug.
We would like to use this upload method in our end-to-end tests to deploy Apps directly from Nexus to a Confluence instance using the REST API. Actually we need to download the files first and install them afterwards. I would like to drop the download step .
