问题
Where can I find for download an old GAE SDK, say 1.9.15 ? I need to find out coverage and maybe use 3rd party API, which do not work well with the recent version.
回答1:
It depends if the respective SDK is still officially supported or not. Both kinds are available in the appengine-sdks GCS bucket.
No longer supported SDKs (like the 1.9.15 one you're seeking) are available in the deprecated folder. Note that they may be under a subdirectory named as the version number without the dots, i.e. 1915 for 1.9.15).
Still supported SDK versions are available in the featured folder.
