Cannot use HtmlUnitDriver in Geb-Spock Grails test because of dependencies problems - maven

Question

I'm trying to use HtmlUnitDriver in Geb-Spock functional test in Grails 2.3.7. I build project using Maven.
When I run test using this driver I get:
java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal
I think I get this error, because I had to exclude xml-apis:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-htmlunit-driver</artifactId>
<version>2.41.0</version>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
</exclusion>
</exclusions>
</dependency>
But I had to do it, because otherwise when I run maven and unit tests are started I get an error:

So I think that's some kind of dependency problems.
But I'm not sure how to handle it.
I tried to analyse the dependency tree, but I'm not sure how to check who wants this org/xml/sax/Locator or org/w3c/dom/ElementTraversal.
I tried excluding more than just xml-apis from HtmlUnitDriver, also xalan and xerces, but it didn't help.

I will be grateful for any remarks on how to resolve this issue.
Edit
I tried versions that were suggested by erdi, so:
selenium-htmlunit-driver 2.26.0
geb 0.9.0-RC-1
geb-spock 0.9.0-RC-1
(and spock 0.7)
I get the error:
2014-05-23 14:37:06,008 [main] ERROR javascript.StrictErrorReporter
- runtimeError: message=[The data necessary to complete this operation
is not yet available.]
sourceName=[http://localhost:8080/search-web-app/static/plugins/jquery-1.11.0.2/js/jquery/jquery-1.11.0.min.js] line=[2] lineSource=[null] lineOffset=[0]
Firefox and Chrome drivers work ok (tests pass).
The reason I would like HtmlUnit driver to work is that we want to able to run tests on Jenkins server. As I understand HtmlUnit is the one that allows it, because it does not open the browser (please correct me if I understand it wrong).

Answer 1

The newest version of HtmlUnitDriver I was able to run with Grails is 2.26.0. Anyway, you should really avoid using HtmlUnitDriver as it doesn't work well with more complex web pages. You're almost always better off driving a real browser in your tests.
Please note that the latest Geb version is 0.9.2 and that you should not use different versions for geb-spock and Grails Geb plugin (0.9.0-RC-1 and 0.7.2).
