AppEngine java solving You do not have permission to modify this app
Switching between multiple projects (and email), I had the following issue WARNING: Error posting to URL: https://appengine.google.com/api/appversion/getresourcelimits?app_id=my_application_id&version=1& 403 Forbidden You do not have permission to modify this app (app_id=u'my_application_id'). Delete: ~/.appcfg_oauth2_tokens_java so that you re-enter the oauth process Also to have templating (here app.id) working, make sure your pom.xml contains <plugin> <groupid>com.google.appengine</groupid> <artifactid>appengine-maven-plugin</artifactid> ... <configuration> ... <!-- Necessary for templating --> <appid>${app.id}</appid> <version>${app.version}</version> ... </configuration> ... </plugin>
