Lately, I noticed my libraries weren’t published to Tomcat when I used a Maven project in Eclipse, even though it was standard war packaging. Since I mostly use Vaadin, I didn’t care much, I published the single vaadin-x.y.z.jar to the deployed WEB-INF/lib manually and I was done with it. Then, I realized it happened on two different instances of Eclipse and for the writing of Develop Vaadin apps with Scala, I used 3 different libraries, so I wanted to correct the problem.
