Error when a plugin has an empty assets/less folder

[csemrau]

When a plugin has an empty assets/less folder, compilation fails.

            throw Error(e);
            ^

Similarly, when the assets/ts folder exsists but is empty, compilation fails.

What is the current condition which makes cplace-asc try to compile LESS resp. TS? The mere existence of the folder? My understanding is that in order to successfully compile LESS or TS, files of specific names must exist in the plugin. Why not make those files a marker, instead of checking the folder?
