This problem can creep up in a number of ways, the main issue is that you do not have the validation-api-1.0.0.GA.jar on your classpath.
I ran into this issue using maven to build my eclipse project. Someone from the gwt 2.3 forgot to include the validation-api jar as a dependency in the maven pom for gwt 2.3. So as a consequence one needs to add this jar explicitly to their project. This thread discusses the issue more in depth... http://groups.google.com/group/codehaus-mojo-gwt-maven-plugin-users/browse_thread/thread/5f6c9324a3119c30?pli=1 -Morgan On May 21, 8:41 am, Sleem <mohammedsl...@gmail.com> wrote: > Dears > > I have built an application using the GWT Eclipse plugin + GXT, when I > migrated to the new SDK 2.3 (Window->preferences->google->web toolkit) > and recompiled my app it gave the following errors > > Compiling module XXX > Validating newly compiled units > [ERROR] Errors in 'jar:file:/D:/SDKs/gwt-2.3.0/gwt-user.jar!/com/ > google/gwt/editor/client/EditorDriver.java' > [ERROR] Line 20: The import > javax.validation.ConstraintViolation cannot be resolved > [ERROR] Line 97: ConstraintViolation cannot be resolved to a > type > [ERROR] Errors in 'jar:file:/D:/SDKs/gwt-2.3.0/gwt-user.jar!/com/ > google/gwt/editor/client/impl/AbstractSimpleBeanEditorDriver.java' > [ERROR] Line 28: Name clash: The method > setConstraintViolations(Iterable<ConstraintViolation<?>>) of type > BaseEditorDriver<T,E> has the same erasure as > setConstraintViolations(Iterable<ConstraintViolation<?>>) of type > EditorDriver<T> but does not override it > [ERROR] Errors in 'jar:file:/D:/SDKs/gwt-2.3.0/gwt-user.jar!/com/ > google/gwt/editor/client/impl/BaseEditorDriver.java' > [ERROR] Line 31: The import > javax.validation.ConstraintViolation cannot be resolved > [ERROR] Line 67: ConstraintViolation cannot be resolved to a > type > [ERROR] Errors in 'jar:file:/D:/SDKs/gwt-2.3.0/gwt-user.jar!/com/ > google/gwt/editor/client/impl/SimpleViolation.java' > [ERROR] Line 25: The import > javax.validation.ConstraintViolation cannot be resolved > [ERROR] Line 40: ConstraintViolation cannot be resolved to a > type > [ERROR] Line 43: ConstraintViolation cannot be resolved to a > type > [ERROR] Line 44: Missing code implementation in the compiler > [ERROR] Line 49: ConstraintViolation cannot be resolved to a > type > [ERROR] Line 49: Missing code implementation in the compiler > [ERROR] Line 70: ConstraintViolation cannot be resolved to a > type > [ERROR] Line 72: ConstraintViolation cannot be resolved to a > type > [ERROR] Line 73: ConstraintViolation<?> cannot be resolved to > a type > [ERROR] Line 77: ConstraintViolation<capture#2-of ?> cannot > be resolved to a type > [ERROR] Line 81: ConstraintViolation<capture#3-of ?> cannot > be resolved to a type > [ERROR] Line 89: ConstraintViolation<capture#4-of ?> cannot > be resolved to a type > [ERROR] Line 93: ConstraintViolation<capture#5-of ?> cannot > be resolved to a type > [ERROR] Line 98: ConstraintViolation cannot be resolved to a > type > [ERROR] Errors in 'jar:file:/D:/SDKs/gwt-2.3.0/gwt-user.jar!/com/ > google/gwt/editor/client/testing/MockSimpleBeanEditorDriver.java' > [ERROR] Line 26: The import > javax.validation.ConstraintViolation cannot be resolved > [ERROR] Line 35: The type MockSimpleBeanEditorDriver<T,E> > must implement the inherited abstract method > EditorDriver<T>.setConstraintViolations(Iterable<ConstraintViolation<?>>) > > [ERROR] Line 107: Name clash: The method > setConstraintViolations(Iterable<ConstraintViolation<?>>) of type > MockSimpleBeanEditorDriver<T,E> has the same erasure as > setConstraintViolations(Iterable<ConstraintViolation<?>>) of type > EditorDriver<T> but does not override it > [ERROR] Line 108: ConstraintViolation cannot be resolved to a > type > [ERROR] Errors in 'jar:file:/D:/SDKs/gwt-2.3.0/gwt-user.jar!/ > javax/validation/super/javax/validation/Configuration.java' > [ERROR] Line 93: TraversableResolver cannot be resolved to a > type > [ERROR] Line 105: ConstraintValidatorFactory cannot be > resolved to a type > [ERROR] Line 182: TraversableResolver cannot be resolved to a > type > [ERROR] Line 182: No source code is available for type > TraversableResolver; did you forget to inherit a required module?
