Unable to get GwtTestCase back up running

[Jörg Hohwiller]

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:

    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 24 more

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

Indeed. I downloaded htmlunit 2.19 from here:

https://sourceforge.net/projects/htmlunit/

after replacing the JAR in my local maven repo it works or at least I get a more promising error:

However from a perspective of a maven user gwt 2.8.x is kind of broken...

[Colin Alworth]

For what its worth, I'm not seeing any such issues in opening classes within the 2.19 jar (source or binary) - any chance you've just got a corrupt local copy, or that your org has a maven repo with a corrupt copy?

[Colin Alworth]

With that update, you might need to look more at your test or project setup - can you share the full log from a mvn test (or whatever you do to run the gwt test cases)?

Any chance of another corrupt local jar?

[Jörg Hohwiller]

Thanks Colin for your quick response.

The broken JAR was 2.619.380 bytes. The correct JAR is 1.906.761 bytes.

I am not using an intermediate maven repo (nexus, artifactory, archiva).

However, I moved/backuped the JAR once more and now maven downloaded a correct version.

Whatever the reason for that error was. I hope it is not reproducable and we can ignore that.

So my assumption was wrong and then GWT release is fine.

[Colin Alworth]

Glad you've got it sorted.

Since we are in the gwt-contrib list after all... if you're interested in seeing GWT updated to the latest HtmlUnit, there's no time like the present for a contribution to avoid this sort of issue in the future!

I already solved tons of problems with missing source dependencies and a fix in gwt.xml

Currently I am stuck here:

However, I will sleep now and hopefully tomorrow I will get some inspiration how to proceed.

If you have a hint or see something I might be missing out, let me know. But do not feel required to fix my code :)

From the GWT side the problem is solved.

Thank you so much

[Jörg Hohwiller]

All solved. No GWT issue. Thread/Topic is done. Thanks for your help.
