I installed COS-AI_21-1-Beta-BigSur(installation package is got from Box folder) which is announced to be compatible with Big Sur, the cplex studio can work properly. But when I try to call cp java lib from eclipse, I got some exceptions which causes the model fails. Could anyone help me on this issue? Thank you.

I configured DYLD_LIBRARY_PATH=/Applications/CPLEX_Studio_Beta211/opl/bin/x86-64_osx in my Eclipse and add the related oplall.jar into my java build path.

When I call CP lib to run optimization model, it throws below exception:
Native code library failed to load: ensure the appropriate library (libopl2010.dylib) is in your path.
Exceptions:
no opl2010 in java.library.path
no oplb in java.library.path
no opl_lang_wrap_cpp in java.library.path
no opl_core_wrap_cpp_java2010 in java.library.path
no opl_core_wrap_cpp in java.library.path
no cp_oaas2010 in java.library.path
no cp_oaas in java.library.path
no cp_wrap_cpp_java2010 in java.library.path
no cp_wrap_cpp in java.library.path
no concert_wrap_cpp_java2010 in java.library.path
no concert_wrap_cpp in java.library.path

When I added the vm argument -Djava.library.path="/Applications/CPLEX_Studio_Beta211/opl/bin/x86-64_osx/", I got UnsatisfiedLinkError exception as below:

Here are the files under opl/bin folder:

Here are the files under opl/lib:
