Good morning,

I'm creating GAE apllication with some endpoints. I was uploading my app many times and everything was OK, but something happened (i think it's my pom.xml) and now i can call 

 maven install

without errors, but when i call

maven appengine:update

console shows FileNotFoundException because appengine-web.xml is missing.

This is my stack trace:

I copied "build" section in my pom.xml from here: https://github.com/GoogleCloudPlatform/appengine-endpoints-helloendpoints-java-maven/blob/master/pom.xml

Of course I'm not suprised, because in my "target" directory i have only "class" directory, but I don't know why "WEB-INF" in this directory is not generated.

--EDIT--

Of course I've created appengine-web.xml in my WEB-INF directory

It was my fault. I had 

<packaging>jar</packaging>

instead of

<packaging>war</packaging>

in my pom.xml, so project was not generated properly.
