Limit Repository Rules

I have a repository with the follow structure of one component:


As the build process only needs the “lib” folder, I created the following rules in “Edit State > Repository Rules” in order to copy only lib folder:

$Source$ >> Source
-$Source.Ultra$\comp\IBObjects* > Source
-$Source.Ultra$\comp\IBObjects\addon** > Source
-$Source.Ultra$\comp\IBObjects\apps** > Source
-$Source.Ultra$\comp\IBObjects\build** > Source
-$Source.Ultra$\comp\IBObjects\docs** > Source
-$Source.Ultra$\comp\IBObjects\packages** > Source
-$Source.Ultra$\comp\IBObjects\samples** > Source
-$Source.Ultra$\comp\IBObjects\source** > Source
-$Source.Ultra$\comp\IBObjects\tutorials** > Source

Everything works fine, however, as I added more rules like this, I got an exception because there are too many rules:

An error occurred while syncing files from the server to the agent. Details: Exception: ProcessException

Is there a way around this limitation?

Hi Rafael,

Thank you for reporting this issue. We have reproduced the error and it is due to a limitation in the Python code base.

We have worked out a way to change our code to avoid this limitation and will upload a new version once this is tested. Meanwhile, we would recommend replacing all your rules with a single include rule. e.g.

$Source.Ultra$\comp\IBObjects\lib\** > Source

This should achieve the same result.

Hi Rafael,

We have uploaded a hotfix for this issue which you can download using the following links:

Thank you for the quick response and fix, Dave!

*The single rule isn’t possible to me, as I tried to simplify as much as possible on problem in my example.
