I followed the instructions on the following page to install gsalib:
It is a very detail one. However, after I git clone the repository "gate-protected" (the source-code under download page point to this git repository) and type "ant gsalib" inside,it gives error information:
[taskdef] Could not load definitions from resource cloverlib.xml. It could not be found.

Could you help me to fix this?
