hmm...we've only seen that error in older Flink version:
https://nightlies.apache.org/flink/flink-docs-release-1.15/docs/flinkdev/ide_setup/#compilation-fails-with-cannot-find-symbol-symbol-method-defineclass-location-class-sunmiscunsafe
Please double-check whether you actually checked out 1.15.1; I can't
reference to sun.misc.Unsafe in the 1.15.1 version of the mentioned
class:

I tried also with a downloaded maven 3.2.5 binary (maven 3.2 has been
disabled in brew):

it failed at the same place with the same error message.
Anything I did is wrong?
