I have a repository with the follow structure of one component:
\comp\IBObjects
\comp\IBObjects\addon
\comp\IBObjects\apps
\comp\IBObjects\build
\comp\IBObjects\docs
\comp\IBObjects\lib
\comp\IBObjects\packages
\comp\IBObjects\samples
\comp\IBObjects\source
\comp\IBObjects\tutorials\
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
Message: Running C:\Program Files\VSoft Technologies\ContinuaCI Agent\hg\hg.exe with arguments … failed with return code 255 and error output: "\*\* Unknown exception encountered with possibly-broken third-party extension win32lfn

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](https://github.com/python/cpython/blob/2.7/Lib/sre_compile.py#L580-L584).
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.
```auto
$Source.Ultra$\comp\IBObjects\lib\** > Source
```
This should achieve the same result.

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.
