Basil James Whitehouse III commented on MNG-4520:
-------------------------------------------------
Olivier, the totsp plugin has been merged into the codehaus one and you are
correct in that the version that I cited is no longer supported. Unfortunately
there are several large GWT projects that don't have the bandwidth to change
and verify the switch at the moment (some being in maintenance only mode).
I filed this to highlight an incompatible change between Maven 2 and Maven 3
but I understand if it won't be fixed if the codehaus plugin works correctly.
FWIW I tested the same project with Maven 3-alpha5 and the Codehaus GWT plugin
version 1.1 and it build successfully with minor pom modifications required.
This project is only the sample one that comes with GWT so I don't expect it to
be exhaustive but a good sign none-the-less. I've attached the pom for this
for future reference.

> The attached sample project builds successfully with Maven 2.0.9 but fails

> I'm using a feature of the gwt plugin to automatically setup the GWT tools to
> compile the source. This downloads the platform specific archive, extracts
> it to the target directory, and then invokes GWTs platform specific complier.
> Under Maven 2 the gwt plugin goal of setup adds the platform specific gwt
> archive to the dependencies for the next extractGwt goal to locate and
> extract the gwt build tools. Under Maven 3 I don't see this same dependency
> being added.
> I know there are newer versions of this plugin and the Codehaus one
> supersedes it, but I can't change the project at this point.
> To run you'll need to add the repo and plugin repo to the pom or settings.xml
