Seems the Maven plugin wasn't able to find the GWT libraries. Could be the Umlaut (Jörg) in your username :

[jbliesener]

Yes, it worked after copying it to a different directory. So, it was either the Umlaut or the spaces in the path name.

Damned be the day on which my parents selected my name... ;-)

Must have been the Umlaut because whitespace in the path works.

LOL ... so be careful when choosing a name for your kids : http://xkcd.com/327/

org.apache.maven.plugin.MojoExecutionException: module file null

Your pom.xml :

<compileTargets>
  <value>com.totsp.sample.Application</value>
</compileTargets>
<runTarget>com.totsp.sample.Application/Application.html</runTarget>

This is not correct, as your Application.gwt.xml resides in it.mycompany.myproject. Modify your pom.xml :

<compileTargets>
  <value>it.mycompany.myproject.Application</value>
</compileTargets>
<runTarget>it.mycompany.myproject.Application/Application.html</runTarget>

great 4 eye are better than one. I' don't know why but I was looking a not real pom.xml

now it work thanks

[nlotz]

Let X be the number of your eyes and let Y be the number of my eyes.

great 4 eye are better than one.

(1) X + Y = 4

great 4 eye are better than one.

(2) X = 1

Substitute X in (1) with (2), which gives (1'):

(1') 1 + Y = 4
(1'') Y = 4 - 1
(1''') Y = 3

=> I must have three eyes !?

Migrate to codehaus

Anyone starting now with GWT and maven should be using the new codehaus gwt-maven-plugin. The older googlecode version of the plugin has been deprecated in favor of the new one. The new plugin has support for GWT 1.6 whilethe old one does not.

Please see following for details including a minimal sample maven project:

<http://groups.google.com/group/gwt-maven/msg/4d4e30b0fdbc1c14?hl=en>

Hi,

Firstly, thank you for the Tutorial.

My Questions:

1. How can I change a port 8888?
2. At the start of the application a build process takes a lot of time, how can I make it faster? I know only how to skip a run of tests.

Thanks beforehand.

[nlotz]

Please see following for details including a minimal sample maven project:
<http://groups.google.com/group/gwt-maven/msg/4d4e30b0fdbc1c14?hl=en>

The version 1.1-SNAPSHOT of the gwt-maven plugin can't be found in central,
so you have to add a plugin repository to your pom.xml that provides it:

<project>
  ...
  <pluginRepositories>
    ...
    <pluginRepository>
      <id>codehaus-snapshots</id>
      <url>http://snapshots.repository.codehaus.org</url>
    </pluginRepository>
    ...
  </pluginRepositories>
  ...
</project>

2. At the start of the application a build process takes a lot of time, how can I make it faster? I know only how to skip a run of tests.

Add these VM-arguments to your launch configuration (on the 'JRE' tab):

-Dgoogle.webtoolkit.compileSkip=true -Dmaven.test.skip=true -Dgoogle.webtoolkit.testSkip=true

[sipungora]

Thank you, nlotz.

Also, I cannot change the port 8888, or?

How can I debug my gwt application? I have tried to debug in eclipse, I've set breakpoints, but es had no effect.

Thanks beforehand.

Maven und extends VLayout

Hi,

1. class A extends VLayout{...}

class B extends A{...}

After buid with Maven I get a Build Error with:

[1, 0] The return type is incompatible with Canvas.getOrCreateRef(JavaScriptObject), Layout.getOrCreateRef(JavaScriptObject), VLayout.getOrCreateRef(JavaScriptObject)

But if I write first without "extends VLayout" I get no error. Then I insert "extends VLayout", do refresh in the GWTBrowser and this work. How can I fix this in order to build my projekt with Maven without errors?

Thanks beforehand.

How can I use SmartGWT EE

I have been trying to use SmartGWT EE from command line and now want ot return to the ease of Eclipse and Marvin.

I have just followed your instructions and have the new GWT version 1.6 and the version 1.1 of SmartGWT wokring. (Great instructions)

I have also paid ofr a license to use SmartGWT EE. How can I add that functionality in to this eclipse/marvin workspace.

Do I use smartGWT EE instrad odf version 1.1 of SMARTGWT or can I use both?

Thanks again

Getting Started

Can we please have a single, current, complete "How To" - "Getting Started" script with a single, working maven archetype that produces a "Hello World" (or similar) application that actually compiles and runs?

I've had to read through five pages of notes here just to find all the various pieces of folk knowledge I need, and even after that, the project created by the codehaus archetype does not build (with the provided maven build goal).

SmartGWT looks like a fantastic product. It'd sure be nice to be able to use it.

FWIW, I'm using Eclipse 3.4 on a Kubuntu 9.10 system.

Thanks,
