java - Updating to htmlunit 2.37.0: setTimeout() build failure

Question

Hej.

First of all: sorry for maybe asking a very simple question, I am very new to Java.

Here is my problem: I updated the dependenciy of an ancient code from using net.sourceforge.htmlunit version 2.8 to 2.37.0 (this was recommended by the Github security bot).

Now my code is not compiling and throws two errors.

Here is the relevant code:

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;

...

WebClient webClient = new WebClient(FIREFOX_3);
webClient.setTimeout(50000);
HtmlPage page = webClient.getPage("http://king.smith.man.ac.uk/mcpred/");

1. First error:

[ERROR] ./MissedCleavageAnalysisAdaptor.java:[64,53] cannot find symbol
[ERROR]   symbol:   variable FIREFOX_3

2. Second error:

[ERROR] ./MissedCleavageAnalysisAdaptor.java:[65,26] cannot find symbol
[ERROR]   symbol:   method setTimeout(int)

I managed to avoid the first error by simply deleting the "FIREFOX_3". Using "FIREFOX" (= newest version of firefox) or "FIREFOX_78" instead did not work and threw the same error.

With the second error, I cannot see the problem. I tried other integers or first defining an integer int timeout = 50000; and webClient.setTimeout(timeout);. Always the same error occurs. It seems like the method setTimeout was not imported. However, this should be imported together with WebClient, shouldn't it?

Can you please give me a hint how to tackle these errors?

Thanks a lot!

Wow thats a huge jump 2.8 was released Aug 5, 2010 and 2.37 in January 28, 2020. The current version is 2.46.0 rom January 2, 2021 - maybe it makes sense to directly migrate to this one.

If you have a look at the release notes you will find this line:

WebClient: deprecated setTimeout() and getTimeout(). Use webClient.getOptions() instead.

for the release 2.11. Means - you have to change your code like this:

webClient.getOptions().setTimeout(50000);

The whole release notes are available here https://htmlunit.sourceforge.io/changes-report.html
