I have created a google-app-engine java project in Eclipse using Google’s Eclipse plugin. My previous attempt to deploy failed. Now, when I retry, I get the following message:
Unable to update app: Error posting to URL : http://appengine.google.com/api/appversion/create?app_id=mybdaywisherversion=1
409 conflict
Another transaction for this user is already in progress for this app and major version. That user can undo the transaction with appcfg.py’s “rollback” command.
Now, I have always used the google-app-engine features from inside Eclipse only and have not a clue how to run the appcfg.py command.
Could not get much help from documentation available over the internet. The only thing I could make out was for mac (I’m on mac), the command to be used is appcfg.sh. Inside Eclipse, I looked where App-Engine SDK is located on my machine and went to that location.
Even found appcfg.sh there. But when I try to run it, it only reports the error “command not found”. Tried various alternatives to run it (like tried running it with sudo, tried running it as ./appcfg.sh by going to whether its located) but no success
Can someone please tell me the step I will have to follow to run the apcfg command?
Better perspective gained about the problem.
Documenting the problem here for the benefit of on-lookers:
I was using Google’s Plugin for Eclipse for a Google App Engine project. An attempt to deploy the application on app-engine server failed because of network problems. Subsequent attempts were failing because the previous attempt had created some kind of lock and that transaction had to be rolled back. The plugin does not provide any way to do this. One has to use appcfg program over command line to rollback. http://code.google.com/appengine/docs/java/tools/eclipse.html has details. The problem I was facing was occuring becuase of OS level permissions on appcfg.sh. Ga ve permission to self using chmod and could get it working.
