According to the title of a earlier response from Thibault in this email chain,
this is concerning https://github.com/apache/incubator-groovy/pull/104
(although after reviewing it again I would not have known it unless he had said
so). According to my conversations with Thibault (again in this email chain)
fixing the tab completion also fixes the broken grapes in the groovy command
line "-e" switch. I would like to use grapes in my "groovy -e
'groovy.grapes.Grape.Grap....'" command and Thibault explained that this was
fixed in his fork because of his fixes but was awaiting for a review to be
merged into main. So it has been month and a half so far. Is someone planning
on approving (or at least reviewing) Thibault's merge soon so I can download
it?
ThanksSiegfried

Hi Siegfried,
I guess you are talking about
https://github.com/apache/incubator-groovy/pull/104 or more specific this
commit:
https://github.com/tkruse/incubator-groovy/commit/c1a2b74839f9c4539d772c311af7acc39c9e41a1
(Grapes: Select higher-level classloader to add new URLs to. )?

Can someone give me an update getting Thibault's fix (patch) to my problem
into a release? Last Thibault explained to me (in a private email) was that he
had implemented the fix (before I discovered the problem) but was waiting for
someone with more expertise in class loaders to merge his changes into the main
stream.
Thanks Siegfried

Thibault: Can you help me reproduce your environment? (1) I cannot find
groovy 2.5.0-Snapshot on http://groovy-lang.org/download.html#distro . Do I
need 2.5.0-Snapshot or will 2.4.4 do? Can I download 2.5.0 without having to
build it myself? Is it difficult to build on windows? Where do I download it
from? (2) I'm confused about that link: it just takes me to the mailing list
page. Can you give a link to the patch? Thanks siegfried

Actually, sorry, this was using Groovy 2.5.0-SNAPSHOT from master.
With my patch to Grape classloading.
http://groovy.329449.n5.nabble.com/groovysh-import-completion-for-Grape-loaded-classes-td5727025.html
With 2.4.x, I get Caught: java.sql.SQLException: No suitable driver
found for jdbc:h2:mem:test_mem
So I guess my patch for grapes does the same as you do.
