Eclipse maven jboss project - what do I need to add to the pom.xml so maven can compile? - eclipse

Question

I managed to set up my Jboss WTP project in maven. Right click on the project > Run as > Run on server (Jboss 7) works fine. But if I go ahead and delete the target directory and then try to execute compile goal it fails with missing dependencies:

If I clean the project so the target directory is populated with classes then try to compile the project all fine:
[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) # DataCollectionServlet ---
[INFO] Nothing to compile - all classes are up to date
I have 1 question:
What exactly should I add to the pom.xml to reproduce the compilation environment of the Run on Server eclipse command ? EDIT: For instance adding:
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
to the pom solved the "servlet API not found" issue - but is it the way to go ? Or should I add something like:
<dependency>
<groupId>org.jboss.as</groupId>
<artifactId>jboss-as-spec-api</artifactId>
<version>7.1.1.Final</version>
</dependency>
(see here). NB: adding the dependencies suggested by m2e plugin would result in a huge pom - moreover I am not sure all of it would be needed (it's a plain servlet/jsp project):
I am on Eclipse Luna Java EE pack, maven 3.1 (the one that comes with eclipse) and using Jboss 7.1.1.Final

Answer 1

I ended up just adding:
<dependency>
<groupId>org.glassfish.web</groupId>
<artifactId>javax.servlet.jsp.jstl</artifactId>
<version>1.2.1</version>
<scope>provided</scope>
</dependency>
This transitively added the servlet-api:
Still don't know if adding this is the right way to add jstl 1.2.1 - notice it adds the jstl 1.2 api (EDIT: it isn't: Standard way of adding JSLT 1.2.1 in a Maven Project?)
I also still have problems with my homebrew jar (Can maven treat WEB-INF\lib the way eclipse (and m2e) does?) but closing this for now.
