Re: 2.3.0m1 errors import javax.validation.ConstraintViolation

[Juan Pablo Gardella]

You need add javax.validation.api classes in your classpath. Now, gwt has this dependency

[ERROR] [xxx] - Line 20: The import
javax.validation.ConstraintViolation cannot be resolved

This seems to be a j2ee class.

You need to add gwt-servlet-deps.jar to WEB-INF/lib. You can find it in build/lib.

GWT 2.2 required validation-api if you're using RequestFactory, but in 2.3, gwt-user has a dependency on it also. For maven projects, we'll update the 2.3 POM with the transitive dependency, but for non-maven projects, it's unfortunately not safe to bundle validation-api like we do with many other jars because some J2EE containers will break if you include validation-api without a corresponding impl.

Google Plugin for Eclipse will add the new dependency to the classpath automatically. If you're not using GPE or maven, you'll have to add it manually for now.

HTH,
