Google appengine deploy error 1

Error posting to URL: https://appengine.google.com/api/appversion/create?app_id= .... anyway... 500 error

if you find that error, you should check your application version.
do not use . and _
change that and check the error message. eclipse will show regular expression for version text.

아무문제 없는데 저런 500에러 뜨면
버전 잘 썻는지 확인해보시길
그냥 숫자만쓰셈
