i have googled , haven't found way prepare issue. configuration or installation issue?

i had problem. did upload first time command line using standard:

~/appengine-java-sdk/bin/appcfg.sh --oauth2 update webap

which prompts me give permission, in browser, , asks me cut-n-paste secret gives me on command line, did.

now can upload android studio using gradle appengineupdate task (it not inquire password again) without problems.

android google-app-engine android-studio android-gradle
