部署到Google App Engine时中途退出后引起的问题

如果部署GAE时正在upload files时退出，下次部署时会报错

Another transaction by user is already in progress for this app and major version. That user can undo the transaction with appcfg.py's "rollback" command

找到eclipse中的GAE SDK目录

如：D:eclipsepluginscom.google.appengine.eclipse.sdkbundle.1.3.8_1.3.8.v201010161055appengine-java-sdk-1.3.8in

执行命令

appcfg.cmd rollback 后面跟gae项目war所在目录 

如 appcfg.cmd rollback D:/spring/eclipse_workspace/taobaoke/war

执行：
