Travis build with scope provided (java websockets)

问题

I am setting up websockets with my Java j2ee servlet application. I was able to write the entire code and got the websockets working using following maven configuration -

<dependency>
            <groupId>javax.websocket</groupId>
            <artifactId>javax.websocket-api</artifactId>
            <version>1.1</version>
            <scope>provided</scope>
        </dependency>

My implementation does not work without <scope>provided</scope> and gives handshake exception: 404 not found.

Now, when I deploy my application on dev machines using travis, it gives exception while creating a build, and throws Java exception that ServerEndpoint class not found. I am assuming that it is because since scope is provided, Travis is not downloading the required jars while building a build on travis.

How do I avoid this, and ensure that we are able to work on local as well as deploy our builds via travis.
