How to add all external jars added in Eclipse when making a WAR (Tapestry)

I'm running my Tapesry project from Eclipse. Then it complies and run on jetty. But i could not find the War file created. But if i goto command prompt and try to build the war file from mvn it will not know about the external jars (for Google API) i have included. how to include those files to MVN manually? or is there any easy way to find the jetty deployment WAR file?

Solution

If you want to get the external jars (Google API) then you must add the jar as a dependency in the pom.xml of the project.
Eg:

     <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>1.7.1</version>
    </dependency>

For Json dependency to your project.
The same way add all the other jars which are dependent to the project pom.xmland then save. Maven will automatically download the dependent jars and it's transitives as well. Following command will do the same.

mvn clean install
