Unable to build feature DITA-OT 3.4/use this plugin with org.dita-community.glossary.preprocess

[AndeeZee]

Hello!
I'm fighting terribly with this plugin. Starting point:
From oXygen 22.1 I copied the DITA-OT3.x (this is DITA-OT 3.4x and Saxon 9.9.) folder and copied the official dependencies, as described per https://www.dita-ot.org/plugins#!org.dita-community.glossary.preprocess, so 2.0.1 from this plugin.

With that, I'm receiving this error:
[mapref] Static error near {...litWords($text, $lang, $deb...} in expression in xsl:variable/@select on line 407 column 103 of i18n-utils.xsl:
[mapref] XPST0017: Cannot find a 3-argument function named
[mapref] Q{http://org.dita-community/i18n/saxon-extensions}splitWords()
... -> the list continues.

After further digging, I found the feature-branch DITA-OT-3.4.
Following things are not working, despite the build guide given:

For building the maven resolver with ant install I receive the error: target does not exists.
So after giving up here, I downloaded the maven-resolver*jar from maven central.

When trying to ant package, a test and therefor the build fails:

Since I'm getting a encoding warnings, maybe it is related to that.

On Linux, I'm receiving
[exec] [WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent!

On Windows, it is
[WARNING] File encoding has not been set, using platform encoding Cp1252, i.e. build is platform dependent!

At the end, I just want to have a final build, which I can use platform independent.

Would you be so kind to have a look into that?

And since this is all a lot of hassle, would you please reconsider the deployment and deploy a direct "usable" platform independent version of this plugin?

Kind regards,
Andy
