Package not found under Unity 2019.3
An error occurred while resolving packages: Project has invalid dependencies: com.microsoft.msbuildforunity: Package [[email protected]] cannot be found
Probably it has something to do with cache folder location.
For default upm source it is [LOCAL APP DATA]\Unity\cache\npm\packages.unity.com
For the one specified in integration guide it appears to be [LOCAL APP DATA]\Unity\cache\npm\pkgs.dev.azure.com\UnityDeveloperTools\MSBuildForUnity\_packaging\UnityDeveloperTools\npm\registry\pkgs.dev.azure.com\UnityDeveloperTools\MSBuildForUnity\_packaging\UnityDeveloperTools\npm\registry
The package version 0.9.1 is not valid when using the package manager. Use the package manager UI and get the closest version to 0.9.1
AFAIK, the package doesn't appear in the package manager - because it can't be resolved - so there's no way to choose a different version. @aka-STInG I have found that version 0.8.3 works. That seems to be the latest working version. (Testing on Unity 2020.1)
For me it shows, but has a warning saying that the version can not be found. Then I just select a more specific version from the UI
Not showing at all for me in package manager unity 2019.4.6f1.
