How do I rollback app-engine deployment

Question

I have an Appengine connected android project (eclipse). I am trying to deploy it as I have done countless times. But this time I am getting the following error.

Unable to update app: Error posting to URL: https://appengine.google.com/api/appversion/create?app_id=myappid&version=1& 409 Conflict Another transaction by user myusername is already in progress for app: s~myappid, version: 1. That user can undo the transaction with "appcfg rollback".

See the deployment console for more details Unable to update app: Error posting to URL: https://appengine.google.com/api/appversion/create?app_id=myappid&version=1& 409 Conflict Another transaction by user myusername is already in progress for app: s~myappid, version: 1. That user can undo the transaction with "appcfg rollback".

So I open my osx terminal and navigate to the folder of my project. When I type

appcfg.py rollback .

I get a terminal error that

appcfg.py: error: Directory does not contain an app.yaml configuration file

Thanks for any direction.

Update

I think I finally found out where it is but now I am getting permission denied when I do

/Applications/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.9.3/appengine-java-sdk-1.9.3/bin/appcfg.sh rollback war

Answer 1

Just an FYI on this: I was using the Eclipse java plugin on Mac (so otherwise didn't have the SDK anywhere), found the command file by digging into the Eclipse package there etc, but predictably enough it didn't run. So I just downloaded the appengine Java SDK, unzipped it, went into bin, ran ./appcfg rollback my/proj command as you see here.

Leave that terminal window open, do not close it, read on...

It opens a web browser and tells you in a very bare bones way to "copy a code and return to the application". I haven't had to roll back a deploy in quite some time, but I don't remember this step. Anyway, I had no idea what that meant until I happened to look at the terminal where I ran the appcfg command, which was now waiting for me to paste in that code. Then all was well.

For Windows user,

Syntax: "<appengine sdk bin folder path>\appcfg" rollback "<war path of your project"

Example: "C:\Users\user\.m2\repository\com\google\appengine\appengine-java-
sdk\1.9.44\appengine-java-sdk\appengine-java-sdk-1.9.44\bin\appcfg" rollback "D:\helloworld\war"

Output of the above will be something like this,

********************************************************
There is a new version of the SDK available.

Latest SDK:

This is for java project using app engine This happens your previous deployment not successfully deployed

go to app engine sdk

C:\Program Files (x86)\Google\appengine-java-sdk-1.9.49\bin

then add

syntax: appcfg.sh rollback your project war folder

Example: appcfg.sh rollback E:myproject\war

Enough!!!

I had the same problem. I solved it using this command on mac: python /usr/local/bin/appcfg.py -verbose --no_cookies --email=account@gmail.com --passin rollback directoryname

where directoryname was the folder where the app.yaml is located. For my case, it was on dropbox folder. so firstly I went to that directory using terminal then I pasted: python /usr/local/bin/appcfg.py -verbose --no_cookies --email=account@gmail.com --passin app

where app defines file name app.yaml

On MAC - in terminal, goto where your sdk directory - /Users/user/Desktop/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.9.20/appengine-java-sdk-1.9.20/bin

do

chmod 777 *

run

bash appcfg.sh rollback /Users/user/Desktop/builder/war

The last parameter is the location of the war inside your project

You can also avoid having to specify your app directory (as it doesn't seen to work for you), by specifying your app id and version in the command itself:

appcfg.py rollback -A your_app_id -V your_app_version

If you have multiple modules then you will need to specify that too with the -M switch.

Answer 7

You will probably find you don't have execute permissions on appcfg

So, if you change to your SDK directory and run

chmod 755 appcfg.sh

Then

appcfg.sh rollback <path_to_app>/war

should work. If not, you may have a WebContent directory, in which case use the path to that. Essentially, appcfg wants to see the WEB-INF directory which contains your appengine-web.xml for the module you're rolling back.

Since you are using Mac, try

appcfg.sh rollback
