Monsieur Olivier,

while we do applaud the release of gwt-maven-plugin 2.1, and understand the benefits of being tied to a specific release, we feel you left us behind!

A lot of the bugfixes done in 1.3-snapshot were (and still are) relevant for GWT 2.0.x as well. We even contributed a patch (issue 180) and we 've been patiently waiting for a stable 1.3 release, suitable for use with GWT 2.0.x.

Do you have any plans to release gwt-maven 1.3 with (backported) fixes for GWT 2.0? It would be a great disappointment if you guys didn't, since (big) projects can't upgrade easily but would really benefit from these fixes.

Vous remerciant par avance,
-fotos

So the mojo gwt 2.1.0 should work with previous gwt version.
So as GWT-180 is closed, you must not have any issue using the last mojo version, if not yes it's an issue.

Hey,

I tested the 2.1 plugin with GWT 2.0.4 and even tho it seems to work, it gives the following warnings:
[WARNING] You're project declares dependency on gwt-user 2.0.4. This plugin is designed for version 2.1.0
Shouldn't this be documented somehow?
In the FAQ page of the plugin It says:
"gwt-maven-plugin is tied to a version of GWT SDK. gwt-maven-plugin must match the GWT DSK version. To use Maven with GWT release prior to GWT 2.1, use gwt-maven-plugin 1.2 and read the documentation."
which can be very misleading. As per you comment above, does it work with earlier versions of GWT SDK or not?

Also I see the following errors in the hosted mode:
00:00:23.969 [DEBUG] Validating newly compiled units
00:00:23.969 [ERROR] Errors in 'jar:file:/Users/xxx/.m2/repository/com/google/gwt/gwt-user/2.1.0/gwt-user-2.1.0.jar!/com/google/gwt/core/client/impl/CrossSiteIframeLoadingStrategy.java'
00:00:23.969 [ERROR] Line 21: The import com.google.gwt.core.client.impl.AsyncFragmentLoader.LoadTerminatedHandler cannot be resolved
00:00:23.969 [ERROR] Line 36: The type CrossSiteIframeLoadingStrategy must implement the inherited abstract method AsyncFragmentLoader.LoadingStrategy.startLoadingFragment(int, AsyncFragmentLoader.LoadErrorHandler)
00:00:23.969 [ERROR] Line 99: LoadTerminatedHandler cannot be resolved to a type
...
etc. I don't know why gwt-user 2.1.0 was loaded in the classpath.

Regarding GWT-180 I added the following lines in my configuration

0.0.0.0

I tested this in both versions of the plugin 2.1.0 and 1.3-SNAPSHOT, but still it will bind to 127.0.0.1.
I did a little search and found that bindAddress is only related to the gwt:eclipse mojo. What about those that do not use eclipse (like myself)? Should the GWT-180 be reopened again?

One last thing is the following warning:
[WARNING] Your POM does not match your hosted webapp WEB-INF/classes folder for GWT Hosted browser to see your classes.
I don't declare any , it gives me the warning but mvn gwt:run works as expected (since as it says here it respects the ${project.build.outputdirectory} as the output directory i.e. target/classes). Is this a "false alarm", since reloading catches up with any source code changes?

Thanks for the 2.1 version of the plugin and your efforts,
-Yannis
