below error at the start of the 101 course, Hands On: Basic Operations workshop....

When running initial 'build', testing phase (during aggregate test?) seems to be having an issue finding the lib for rocksdb. When I check, there is indeed no file (or similar named file) in the directory.

Following instructions here

Have done a lot of error searching but am struggling to find a solution. Any guidance or suggestions, fixes or similar most welcome.

command:-

./gradlew build

returns output :-
