I got the IDE in CPLEX Optimization Studio to work on Catalina using the following steps:
1. Download this IBM JDK
https://ibm.box.com/s/6nw16tgpe5oxdq52nh7hpldwyzhpsp9v.2. Expand the tar file. This will create a folder named Contents. Don't rename it.
3. Move that folder to /Applications/CPLEX_Studio129/opl/oplide
4. In the same folder /Applications/CPLEX_Studio129/opl/oplide, right-click on the Oplide app, and choose Show Package Contents
5. Navigate to /Applications/CPLEX_Studio129/opl/oplide/Oplide.app/Contents/Eclipse and open the file oplide.ini with TextEdit.
6. The second line is /Applications/CPLEX_Studio129/opl/oplide/jre/bin/java Change it to /Applications/CPLEX_Studio129/opl/oplide/Contents/Home/bin/java
If you have already installed CPLEX, refer this
manual to uninstall/reinstall it.
