mavenized version?

[Meredith Gregory]

Dear Scalagwt'rs,

i was attempting to use the hello world sample for a mavenized scalagwt build i found here. This works up to the call to the gwt compiler. i can invoke this via

> mvn gwt:compile

or as part of 

> mvn package

No matter which version of the gwt-maven-plugin (2.4.0 or 2.5.0-rc1) this phase fails -- though in different ways. With the former i get a compilation failure (see below). With the latter i get a failure with the configuration of the command line (see below).

Essentially, i'm using this on a small variant of the Showcase sample which i've merely put into a different package, and with a different module file. i've got this variant to build using the ant script, but would love to get it running under maven.

Best wishes,

This part worries me:

[WARNING] You're project declares dependency on gwt-user 2.4.0-scalagwt. This plugin is designed for at least gwt version 2.5.0-rc1

What's the build error if you're using v2.4.0 of the gwt-maven-plugin?

Are you able to get my barebones project working at all (from nearly a fresh git clone)?

[Meredith Gregory]

Dear Nate,

Thanks for asking! i've included the trace of the error that happens using 2.4.0 gwt-maven-plugin. 

i've modified my project to be a version of the Showcase sample, released with the scala-gwt samples. However, i've changed the code to simply be in a different package. So, it's not quite the same as your HelloWorld, but very similar. My modified version builds just fine with the ant build script. Additionally, it compiles under mvn up to -- but not including -- jribble compilation. When i then call 

> mvn gwt:compile

or

> mvn package

i get the compilation error, below.

Best wishes,

[Nate Bauernfeind]

Can you fork my sample gwt-maven-plugin and push your changes to see if I can take a stab at fixing this?

[Meredith Gregory]

Dear Nate,

Thanks for following up. i put up a version under one of my projects already on github. Does that work?

Best wishes,

--greg

[Nate Bauernfeind]

Just to give you a heads up, I was able to reproduce your issue with the jar's I've built previously.

I'm going to try and get the showcase sample up and running with as few modifications as I can manage. I don't have time right at this moment, but it's on my todo list. I'll keep you updated.

[Meredith Gregory]

Dear Nate,

Thanks! Do let me know if you get things going, and don't hesitate to ask if you think i can be of help.

Best wishes,

--greg

[Meredith Gregory]

Dear Nate,

i just thought i'd check in and see how things might be progressing on this front.

Best wishes,
