Hi,
Either I'm doing something wrong, or there is something wrong with the
way the eclipse plugin hands out classpaths to the gwt Compiler. The
Compiler loads the Generator class from <generate-with name=""> rules
when parsing the .gwt.xml files, but it is not passed the war/WEB-INF/
classes (aka, eclipse output) directory on it's classpath, resulting
in a ClassNotFoundException when you hit the compile button.
Create new Web Application (using the GWT SDK 1.6), name: plugintest,
package: plugintest
Create (empty) interface plugintest.client.Foo
Create (empty) class plugintest.client.FooGenerator
Edit plugintest.Plugintest.gwt.xml, add:
<generate-with class="plugintest.client.FooGenerator">
<when-type-assignable class="plugintest.client.Foo"/>
</generate-with>
When you hit the GWT Compile Project button, the error you get is:
Loading module 'plugintest.Plugintest'
[ERROR] Unable to load class 'plugintest.client.FooGenerator'
java.lang.ClassNotFoundException: plugintest.client.FooGenerator
... instead of the expected exception that FooGenerator doesn't extend
the Generator base class.
Compiling manuall with
java -cp %GWT_HOME%/gwt-user.jar;%GWT_HOME%/gwt-dev-windws.jar;src;war
\WEB-INF\classes com.google.gwt.dev.Compiler plugintest.plugintest
gives the same result.
Note that the gwtc target in a build.xml generated by the
webAppCreator does include the compiled classes in the classpath of
the Compiler.
It can be circumvented by adding war/WEB-INF/classes as a source
folder or something, but that's obviously not intended.
Is this a bug in the plugin, or is there a proper solution (and why is
that not default) ?
