This application does not exist (app_id=u'google.com:nbsocialmetrics')

问题

I know others have posted similar issues but after trying their solutions I think this is a different problem.

I'm trying to get a multi-module application functioning for Google App Engine. I'm developing it from this sample code.

I was able to get my application running successfully in the development server but I encountered the following error when I tried to upload to Google App Engine with the command mvn appengine:update:

I've listed a bunch of references to similar problems but here is a summary of what they say and why it didn't work for me:

1] Permissions - Make sure you have permission to upload code to this google account. I verified by going to http://appengine.google.com, clicking my app, nbsocialmetrics, and clicking permissions. There it lists the correct Google account and it says the Role is owner.

2] Delete cookies - To ensure my credentials hadn't been cached, I deleted the file ~/.appcfg_oauth2_tokens_java (I'm on a Mac). Apparently this file used be called .appcfg_cookies which you'll see in the references I've listed below.

3] appcfg.sh --no_cookies - Some people suggested another approach beside #2 above: call c. However, I'm using mvn appengine:update and it would take a lot of work to figure out how mvn appengine:update and mvn appengine:update relate to each other. So I didn't try this.

回答1:

If you are using windows, you can try after delete this file

C:/Users/{username}/.appcfg_oauth2_tokens_java (maybe somthing like this file.)

I'm using eclipse maven plugins to build and packaging. By this way i could fix it !

I noticed how the error I got was different from other reports of this issue. Notice the prefix google.com: in the error message I received:

This application does not exist (app_id=u'google.com:nbsocialmetrics').

This prefix wasn't in the other reports of this problem. So I tracked that prefix down to the file I was modeling after: appengine-application.xml.

My solution was to remove the prefix from my appengine-application.xml so it now reads this:

<application>nbsocialmetrics</application>

Instead of:

<application>google.com:nbsocialmetrics</application>

I have no idea why that prefix was in the sample code.
