Sometimes when we deploy our appengine application, it stucked in the middle or happens any accidents, we tried to redeploy but failed because it showed there is another same transactions had been running. Therefore, there is a need to rollback the deployment.
How we do in windows?
Now, locate your appengine sdk installation folder, open window command prompt (cmd), and then cd to [appengine installation folder]\bin\
Before that, locate your web application’s build directories, such as: “C:\Users\fyhao\Documents\NetBeansProjects\fyhao1_2\build\web”
Then, type:
appcfg.cmd rollback “C:\Users\fyhao\Documents\NetBeansProjects\fyhao1_2\build\web”
It will rollback now.
