Hello folks
I am interested in learning GWT and I'd like to use Maven as a build tool so I navigated to http://mojo.codehaus.org/gwt-maven-plugin/user-guide/archetype.html and created a test project.
I am using OSX 10.6.8, Eclipse 3.6.2, GWT Eclipse plugin 2.5.0 and here is my pom.xml
<?xml version="1.0" encoding="UTF-8"?>

The problem:
when I execute "mvn package" the printout ends with "BUILD SUCCESS" but it also contains this weird line (Ignored 80 units with compilation errors in first pass.):
....
[INFO] --- gwt-maven-plugin:2.5.0:compile (default) @ test ---
[INFO] auto discovered modules [se.anatoly.test.test]
[INFO] Compiling module se.anatoly.test.test
[INFO] Validating units:
[INFO] Ignored 80 units with compilation errors in first pass.
[INFO] Compile with -strict or with -logLevel set to TRACE or DEBUG to see all errors.
....
I tried "mvn package -Dgwt.logLevel=TRACE" and then I see a thousand of lines like below, which I don't understand what it is (what's this validation? and why all these errors?):
....
[INFO] Validating units:
[INFO] Errors in 'com/google/gwt/editor/client/EditorDriver.java'
[INFO] Line 20: The import javax.validation.ConstraintViolation cannot be resolved
[INFO] Line 97: ConstraintViolation cannot be resolved to a type
[INFO] Errors in 'com/google/gwt/editor/client/impl/AbstractSimpleBeanEditorDriver.java'
[INFO] Line 28: Name clash: The method setConstraintViolations(Iterable<ConstraintViolation<?>>) of type BaseEditorDriver<T,E> has the same erasure as setConstraint
....
Could anybody explain to me what is going on and how I get rid of these errors?
Best regards,
Anatoly
