Hi there,
I am maintaining my project and did some upgrades including gwt 2.8.2 from
2.7.0.
Now my JUnit based on GwtTestCase is failing with:
java.lang.NoSuchFieldError: FIREFOX_38

I found out that gwt-dev is depending on htmlunit 2.19 but due some
dependency management I was using 2.29 instead.
So I overrode this again in my pom.xml:
<dependency>
<groupId>net.sourceforge.htmlunit</groupId>
<artifactId>htmlunit</artifactId>
<version>2.19</version>
<scope>test</scope>
</dependency>
Now I am getting this error:

What is also interesting: When I do go to BrowserVersion.class in the
htmlunit-2.29.jar of my maven-dependencies in Eclipse, it opens fine and
shows the sources.
However, with version 2.19 Eclipse does not open BrowserVersion.class
properly and instead shows:
java.util.zip.ZipException: invalid LOC header (bad signature)
at java.util.zip.ZipFile.read(Native Method)
at java.util.zip.ZipFile.access$1400(ZipFile.java:60)
...
So to me it seems like this:
-gwt-dev is hardwired against htmlunit 2.19 and refers to specific
BrowserVersion constant fields that are gone in newer versions.
-for some strange reason htmlunit 2.19 deployment in maven central is
broken (has a damaged JAR deployed to the world)
Any ideas or workarounds? I already tried 2.18 and 2.20 with no luck (e.g.
getting NoSuchFieldError: INTERNET_EXPLORER_8).
Seems I am locked out by gwt. Also does not work with 2.8.1.
Thanks in advance for any hint or suggestion.
Kind regards
Jörg
