Issue
Unable to open 2nd instance of Eclipse when one is running currently (continuous regression run) on macOS.
When I tried in terminal, I got the below message:
"Script started, output file is /dev/null java_home: unrecognized option
--request
script done, output file is /dev/null"
Solution
In Terminal use the command:
open -n -a Eclipse
Note: You can only open a different workspace, Eclipse does not support two instances accessing the same workspace.
