git-client-plugin fetches the list of submodules using:

git config -f .gitmodules --get-regexp "^submodule\\.(.*)\\.url"

Which returns entries in the form:

submodule.<name>.url <value>

It then uses

"Pattern.compile("^submodule\\.(.*)\\.url", Pattern.MULTILINE)"

to extract the module name (CliGitAPIImpl.java#L1062).

I have a thirdparty submodule called "urlesc" that lives in a repo that looks something like:

submodule.src/git.repo.local/urlesc.url git.repo.local:/gitroot/thirdparty.urlesc.git

If the value contains ".url" the regex will match too much of the line.

It thinks the name is "src/git.repo.local/urlesc.url git.repo.local:/gitroot/thirdparty" and so tries to run:

git config --get "submodule.src/git.repo.local/urlesc.url git.repo.local:/gitroot/thirdparty.url"

which is incorrect.

The regex should be something like

"^submodule\\.(.*)\\.url "

(note the space after url) or

"^submodule\\.([^ ]*)\\.url"

.
