Maven dependencies not visible in WEB-INF/lib

Question

I'm having this weird problem making my project Maven-based. I created a new Maven project in Eclipse and enabled the Dynamic Web facets. But during runtime now it throws ClassNotFoundException because the Maven dependencies are not copied to WEB-INF/lib directory. I even tried adding the copy-dependencies section in POM, but it didn't help.

Someone here seemed to have solved this the right way, but I guess he forgot to mention the solution ::(

Answer 1

you want to use the copy-dependencies plugin

see this post and the docs

Answer 2

This should have nothing to do with eclipse and m2eclipse, and optionally for better support - m2e-wtp. Also, you don't need copy-dependencies. Here are a few possible reasons:

• you should invoke mvn package (or right-click > maven > package) and obtain a war file - the <packaging> (in the pom) must be war
• your dependencies should be with the default scope (if they are provided or test they will not be included in the archive)
• if you are running the project as dynamic web project on a server within eclipse, then you should open the project properties (right click > properties) and select "Deployment Assembly". There click "add", select "build path entries", and choose "maven dependencies". This will instruct WTP to send the maven dependencies to the server dir.
