Maven vs. Eclipse Project Facets for Java EE 6

问题

I have created Maven projects inside Eclipse with these archetypes:

ejb-javaee6
webapp-javaee6

The projects were created without facets.

Does it make sense to convert such Maven projects into faceted form?

Which facets would be helpful and which ones could cause trouble for a Maven project?

Specifically: Would any of the following project facets be in conflict with something that is in the responsibility of Maven?

Java
JavaScript
EJB Module
Dynamic Web Module
GlassFish Deployment Descriptors Files
JavaServer Faces

I have the impression that converting a Maven project to faceted form would mean mixing two worlds. Therefore I tend to NOT enable ANY project facets.

But where I work we have examples of Maven projects that are in faceted form and I was wondering whether there might be (risk-free) benefits to it.

回答1:

Eclipse facets and maven archetypes are orthogonal - i.e. they have no influence on each other, or rather no knowledge of each other. You can safely add the facets if it will facilitate your work with eclipse.

回答2:

After some experimenting I think I have something that works (except that I cannot get m2e to accept Java 1.7 for EJBs).

Versions:

Eclipse Juno 4.2
m2e 1.3.1
GlassFish 3.1.2
JDK 1.7.0_17 (Oracle)

IMPORTANT USAGE NOTE: With the setup below, you should disable automatic publishing to GlassFish ("Never publish automatically") if you want to run Maven clean & install. For the usual editing and saving work in Eclipse, automatic publishing can be enabled and seems to work fine. Only when starting Maven explicitly (inside Eclipse) did I encounter problems.

Setting up an EJB project with Maven in Eclipse

Create Maven projects in Eclipse with these archetypes:
 ejb-javaee6
 ear-javaee6
 webapp-javaee6

webapp-javaee6
--------------
- Convert to faceted form, select GlassFish in Runtimes and enable:
  - Dynamic Web Module
  - GlassFish Deployment Descriptors Files
  - Java
  - JavaScript
  - JavaServer Faces
  Further configuration available...
  - Content directory: src/main/webapp
  - NOT checked: Generate web.xml deployment descriptor
  - JSF Capabilities (all defaults): JSF 2.1 + PrimeFaces selected
    CHECKED: "Include libraries with this application"

ejb-javaee6
-----------
- Convert to faceted form, select GlassFish in Runtimes and enable:
  - EJB Module
  - GlassFish Deployment Descriptors Files
  - Java
  Further configuration available...
  - NOT checked: Generate ejb-jar.xml deployment descriptor

ear-javaee6
-----------
- Convert to faceted form, select GlassFish in Runtimes and enable:
  - EAR
  - GlassFish Deployment Descriptors Files
  Further configuration available...
  - Add EJB and WEB projects as dependencies
  - Content directory: src/main/application (META-INF location used by Maven)
  - NOT checked: Generate application.xml deployment descriptor
