GWTTestCase failes with "Cannot locate declared field class org.apache.http.impl.client.HttpClientBuilder.sslContext"

[Kay Pac]

This seems to be an error related to htmlunit. Is this a problem in my configuration? I have switched to building gwt-maven-plugin from HEAD and also the latest gwt sources. I think htmlunit is embedded in gwt? I don't see it as a maven dependency that I might be able to switch out, so I figured changing the htmlunit version would be barking up the wrong tree. Has anyone seen this error? I googled and found:

https://sourceforge.net/p/htmlunit/bugs/1692/

Any help would be appreciated.

GWT trunk/2.8 uses HTMLUnit 2.19 since mid-February, with Apache HTTP Client 4.5.1, so that bug doesn't apply (at least not directly).

 

Any help would be appreciated.

Do you have Apache HTTP Client on the classpath?

I do, thanks for the tip - I found an old dependency and excluded it, and tht got rid of that error. I now get:

[INFO] [ERROR] RunStyleHtmlUnit: Unknown browser name FF17, expected browser name: one of [FF38, Chrome, Edge, IE8, IE11]
[INFO] [ERROR] shell failed in doStartup method

I'm worried I still have a bad configuration, although its easy to get rid of that, I can't find the specification for FF17 anywhere in my problem.

Thank you very much for your assistance!! I compiled gwt-maven-plugin from trunk, and gwt also, should I be getting that error?

That FF17 comes from here: https://github.com/gwt-maven-plugin/gwt-maven-plugin/blob/7e3d233bc4281b2881a0827c2421fd250f64ad0b/src/main/java/org/codehaus/mojo/gwt/shell/TestMojo.java#L116

HTMLUnit 2.19 no longer emulates FF17, contrary to the previous version GWT was using (2.13), and is used in 2.8 beta 1. So the problem is gwt-maven-plugin needs to be updated. I'd suggest filing an issue.
