Handling API versioning issue

[Eric So]

Hi All,

I just followed the instruction from our external documentation page, https://cloud.google.com/endpoints/docs/frameworks/java/handling-api-versioning.

I have an API application deployed with application version = 1 with api version v1.0 two months ago. Today, I am trying to deploy a new API version v1.2 or v1.3 to the same application version. I assume the following endpoints should work:

1) https://1-dot-xxxxx.appspot.com/_ah/api/user/v1.0

2) https://1-dot-xxxxx.appspot.com/_ah/api/user/v1.2 or https://1-dot-xxxxx.appspot.com/_ah/api/user/v1.0

However, when I opened the https://1-dot-xxxxx.appspot.com/_ah/api/explorer in the browser, I could only find the older version we had. But not the new one. I tried to curl or ping the url with the new API version. It returns 404 NOT FOUND.

I want to ask if it is possible to redeploy Java App to the same app version. Also, do we need to keep multiple version of source code in the same repo and re-deploy everything again?

Regards,

Eric So

Hi Eric, 

If you deploy the new API version to the same application version 1, you'll find it under the same 1-dot-xxx address: the one you mention. 

In such cases, it is more effective to open a bug / issue in the public tracker. The tracker is dedicated to such issue, whereas a group such as this one is meant for general discussions and exchange of opinions.

Sorry that this reply thread does not show up in my inbox. I will open a bug / issue to track this. 

And I found out from one developer that the application needs to setup different classes for different versions. We need to deploy the whole application with different versions in one jar or war to support multiple versions in one endpoint.

Hi Eric, 

For related versioning information you may consider checking the "Cloud Endpoints API versioning features" sub-chapter of the "API life cycle management" page.

Thanks. Take a look at it now.
