Files under folder spring-cloud-starter-stream-processor-scriptable-transform ends up being longer than the limit on windows, causing problems with the git checkout on such platforms :

Article https://ourcodeworld.com/articles/read/109/how-to-solve-filename-too-long-error-in-git-powershell-and-github-application-for-windows describes the problem and a possible solution:

git config --system core.longpaths true

which worked for me.

Maybe this information should be added to the README.adoc ?

Feel free to contribute such a NOTE into the README.adoc under the build section. Although it is general Git issue, so doesn't sound like related to this project...

Thanks

Since it happens at git clone time, it is not a build problem but a "getting the source code" problem. Agreed it is a general git issue, but scriptable-transform do have long filenames and thus triggers that problem (as will any other project with long filenames).

What I want to say is : the notice about this git attribure for long paths would be better placed close to the place and time where a contributor decides to get the source code from github. Maybe it could be placed in the README.adoc of every app-starter project having long filenames (would have to find this with a script or manually) and also in the introduction text at top of starter page https://github.com/spring-cloud-stream-app-starters ?

I will contribute a note for the former, but I'm not sure on how to do the latter.
