App Engine Maven compilation error

I am trying to deploy an application on to Google App Engine. when I execute mvn clean install I get this error

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.
1:compile (default-compile) on project testproject: Compilation failure: Compilation failure:
[ERROR] /D:/appengine-java-sdk-1.9.27/appengine-java-sdk-1.9.27/demos/testproject/src/main/java/com/danter/google/auth/GoogleAuthHelper.java:[13,42] package com.google.api.client.json.jackson does not exist

I added the following dependencies:

<dependency>
    <groupId>com.google.api-client</groupId>
    <artifactId>google-api-client-java6</artifactId>
    <version>1.12.0-beta</version>
</dependency>
<dependency>
    <groupId>com.google.oauth-client</groupId>
    <artifactId>google-oauth-client-jetty</artifactId>
    <version>1.12.0-beta</version>
</dependency>
<dependency>
    <groupId>com.google.http-client</groupId>
    <artifactId>google-http-client-jackson2</artifactId>
    <version>1.12.0-beta</version>
</dependency>

You are missing the library google-http-client-jackson. Add it to your POM like this:

<dependency>
    <groupId>com.google.http-client</groupId>
    <artifactId>google-http-client-jackson</artifactId>
    <version>1.12.0-beta</version>
</dependency>

As a side note, I suggest you introduce a property holding the 1.12.0-beta version. If you upgrade in the future, you won't have to change every dependency but just the property.
