Exception: Unable to find javac

Thanks for the nice tool.

Could you please give me a hint how to solve this? I didn't realize that I need to set java env?

I try to run a eval method in pyserini

python -m pyserini.eval.trec_eval -c -mrecip_rank ...

and in pyclass.py it import jnius
Then it raise the exception as above:

File "/root/.conda/envs/open/lib/python3.10/site-packages/jnius/env.py", line 351, in get_jdk_home
    raise Exception('Unable to find javac')
