Re: [CZT-Devel] Fixes to build standalone CZT for JDK11 and Maven 3.8.1

[Julian R. <jro...@gm...>]

Thanks to Anthony Hall who followed my steps to build CZT on a Windows 7 /
JDK 11 platform (versus my Windows 10 / JDK SE 11.0.1) which exposed two
problems:
- an addition is needed to the toplevel code/pom.xml to specify a later
(default) version of plexus-archiver.
- my changes to gnast work when the path name contains spaces, like
"C:/home/some
stuff/CZT/", but break when there is no space, like "C:/home/some_stuff/CZT/".
A further change to the file
code\dev\gnast\src\main\java\net\sourceforge\czt\gnast\project.java fixes
this.

Fixes for both of these problems are included in this zip file at
https://drive.google.com/file/d/19x2cnIHbajH1vEAk2JZztlEqVW03dNd9/view?usp=sharing
which replaces that in step 2 of my 11 July post.
This zip file includes all the changes and bug fixes to CZT since my 11
July post to date.

With thanks,
julian
