Re: [m2e-wtp-dev] An issue with dynamic web module facet
m2e-wtp infers the Dynamic Web Facet from the web.xml content, if it exists. So typically, if a web.xml says I'm 2.4, that's the facet that m2e-wtp will try to set upon project configuration updates.

Now, if the user manually changed the facet to say 3.0, in Eclipse preferences, but still keeps the web.xml unchanged, then m2e-wtp will try to downgrade the facet from 3.0 to 2.4.

Few years ago, that was working fine, then WTP changed the rules, the only authorized facet changes are described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=393801#c5
- The enablement only considers valid change operations:
   + EAR facet can be upgraded from 1.4 to any version until 6.0 and from 5.0 to 6.0.
   + AppClient facet can be upgraded from 1.4 to any version until 6.0 and from 5.0 to 6.0.
   + EJB facet can be upgraded from 2.1 to any version until 3.1 and from 3.0 to 3.1.
   + Web facet can be upgraded from 2.4 to any version until 3.0 and from 2.5 to 3.0.
   + Connector facet can be upgraded from 1.5 to 1.6.
Downgrading is forbidden. And I reckon this is unfortunate.

As an improvement, I guess m2e-wtp, could just display a warning in case a forbidden Facet change is detected, and just not perform it.

You can file a bug in https://bugs.eclipse.org/bugs/enter_bug.cgi?product=M2E-WTP

Hi,

A user on Eclipse IRC channel at Freenode have been facing an issue with a persistent " Cannot change version of project facet Dynamic Web Module to 2.4" error on his Maven JEE project. Apparently, it seems to be a very usual issue in m2e-wtp http://stackoverflow.com/questions/18122336/cannot-change-version-of-project-facet-dynamic-web-module-to-3-0/18632054#18632054 . The amount of votes and answers is very high for an Eclipse IDE related question.
Is there a bugzilla entry related to this issue? Is there already something in place to fix it? At least, it seems like users are really in need a guidance in such case, could some quick-fixes help ?

Cheers,
