I'm trying to open an old project in Eclipse Oxygen. The Google Cloud Platform plugin is installed and working.
My old project references the old blobstore libraries.
The problem is that the project doesn't compile anymore because it's missing the libraries for blobstore.
I looked in Build Path > Add Libraries, but only see the new GCP libs:
Where can I find these libraries and how to install them in my project in Eclipse?
@BriandeAlwis provided the answer. I'm posting it here as the answer since he only posted this in a comment.
That you're not seeing the App Engine libraries in that dialog suggests that your project is not configured as an App Engine Standard project. You should be able to right-click on the project and select Configure > Convert to App Engine Standard Project.
