java maven eclipse tomcat failed to start NoClassDefFoundError

I'm struggling with eclipse+tomcat configuration. I deployed my app on the cloud but I'd liek to do some changes offline (it's faster) and then deploy something working. I have web project set up using maven. I have 2 dependencies(not mentioning essential javax): org.json and joda-time. The problem is I can not figure out how to download those dependencies. Every time I want to run the project tomcat fails to start with a long stack trace, but I know that the problem is that line: Caused by: Java.lang.NoClassDefFoundError: javax/json/JsonObject. That means, dependencies jars aren't there(int WEB-INF/lib I think). I've tried ppm on project->maven->update project, ppm on server->clean, ppm on server->publish. Also I checked project->properties->Deployment Asembly and Maven Dependencies are there... I've searched a lot thourgh the web and I'm running out of ideas. Thanks for any help, cheers!

I think that tomcat may not be providing Java EE API, please try changing

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>7.0</version>
        <scope>provided</scope>
    </dependency>

to

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>7.0</version>
    </dependency>

(remove provided scope).
