Eclipse does not include dependencies for maven-wtp [message #1711462]

Hello all,

I have been trying for quite some time now to get eclipse to work with a maven-based wtp2.0 project. The problem is *always* that some required dependencies are not deployed to the tomcat server.

Just to clarify: If I use "mvn package" to create a war, then everything works and all dependencies are included. The problem seems to be with eclipse in this case.

Essentially I have a "server" maven-wtp which has a "core" dependency which is a maven project I am also developing using eclipse. In addition the project depends on another external jar which I obtain from mvnrepository.com. This is noted as a
dependency in the project's pom.xml.

I took a look at ".settings/org.eclipse.wst.common.component" which supposedly stores dependencies in eclipse, it shows my core module:

        <dependent-module archiveName="core-1.0.0.jar" deploy-path="/WEB-INF/lib" handle="module:/resource/core/core">
            <dependency-type>uses</dependency-type>
        </dependent-module>

However, the external dependency is not showing, it is not deployed and my server throws an exception:

java.lang.NoClassDefFoundError

Just to clarify: the maven dependencies *do* show up in the "Deployment Assembly" section and are supposed to be deployed to "WEB-INF/lib"

I am using Mars.1 Release (4.5.1) and m2e-wtp (1.2.1.20150819-2220).

Does anyone know how to fix this issue?

It's best to ask on the WebTools forum.

Is it possible to move the thread?

I use Thunderbird and the best I can do with that is add another
newsgroup to the "CC" list. I don't think it's possible to move posts,
but I'm not sure...
