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

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:

[INFO] Scanning for projects...

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.
