Put the generator outside of your <source> path so that the gwt compiler does
not try to compile it to javascript.
You were right.
Now I changed the path and the generator is working but there is another
problem
public class rttiGenerator extends Generator {
@Override
public String generate(TreeLogger logger, GeneratorContext context,
String typeName) throws UnableToCompleteException {
JClassType classType;
try {
classType = context.getTypeOracle().getType(typeName);
SourceWriter src = getSourceWriter(classType, context, logger);
*src.println("public void test(){}"); *
src.commit(logger);
return typeName + "Generated";
} catch (NotFoundException e) {
e.printStackTrace();
}
return null;
}
public SourceWriter getSourceWriter(JClassType classType,
GeneratorContext context, TreeLogger logger) {
String packageName = "pl.cba.lukaszbaczek.client";
String simpleName = classType.getSimpleSourceName() + "Generated";
ClassSourceFileComposerFactory composer = new
ClassSourceFileComposerFactory(
packageName, simpleName);
composer.addImport("com.google.gwt.user.client.ui.Button");
composer.setSuperclass("Button");
PrintWriter printWriter = context.tryCreate(logger, packageName,
simpleName);
if (printWriter == null) {
return null;
} else {
SourceWriter sw = composer.createSourceWriter(context,
printWriter);
return sw;
}
}
}
