Grails 1.3.1 and SmartGWT dependency problems

[Carlos]

Hi all,

I'm trying to create a Grails 1.3.1 application using the gwt plugin
and SmartGWT. I'm getting the following stacktrace (see below) when
running 'grails compile-gwt-modules'. One thing to note is that I
don't have the smartgwt jar files under /lib/gwt, I'm using Grails new
dependency management solution from the BuildConfig.groovy file. Any
suggestions would be much appreciated!

Hi Carlos,

It's seems to me that is a library path problem.
Make sure that lib/gwt is created in the project's root, then, copy
the smartgwt.jar and smartgwt-skins.jar to lib/gwt folder.
Add both files to build path of your project. Go to Configure build
path / Libraries tab / Add JARs and point to the smartgwt files in lib
folder.

It's working to me.

Hugs,

Rogério Alcântara Valente.

hanks for your answer Rogerio. You are right the problem is in the
classpath and because I'm using the Grails 1.3.1 dependency management
system (using the BuildConfig.groovy file) I don't have a lib/gwt
folder. I have modified the plugin to allow the gwt jars to be managed
by the dependency system instead of requiring them to be under lib/
gwt. I'll try to get it incorporated to the next release of the
plugin. The diff is as follows:

--- a/scripts/_GwtInternal.groovy
+++ b/scripts/_GwtInternal.groovy
@@ -404,6 +404,10 @@ gwtRun = { String className, Closure body ->
// Add the plugin's module paths.
pathElement(location: "${gwtPluginDir}/${gwtSrcPath}")
pathElement(location: "${gwtPluginDir}/${grailsSrcPath}")
+
+ grailsSettings.runtimeDependencies.each { dep ->
+ pathElement(location: dep)
+ }

// Add the DTO source path if that plugin is installed in
// the current project.

Hi Carlos,

I am not sure if your patch will work in general: as far as I
remember, the reason why the GWT plugin introduced the additional
lib/gwt directory was due to the requirements of GWT compiler: it
needed to have in its classpath source folders and GWT prepared jars
(containing .*gwt.xml and *.java files) ONLY. I am not sure if this is
still valid with GWT 2.x.

Please, let us know if your patched GWT plugin can compile and start
the development mode, if you add to your dependencies a non-gwt jar
file.

Cheers,

Predrag

Yes Pedrag, this is still valid on GWt 2.x.

I'm using GWT 2.0.3 and SmartGWT 2.2.

Cheers,
Rogério.

Note that all runtime dependencies are included in the WAR file. This
isn't what you want for most GWT libraries I think. In fact, I'm
pretty sure dependencies in "lib/gwt" aren't included in the WAR file.

So, what I propose to do is add a special "gwt" dependency
configuration. The plugin will then include all dependencies in that
configuration on the gwtRun classpath.
