hi! I have tried to run the code but I really can't solve the following problem. I have java installed and have set the environment path. But It still can't work.

hi! I've solve the above problem. Unfortunatelly, I met another one:

File "jnius\jnius_export_func.pxi", line 22, in jnius.find_javaclass
File "jnius\jnius_utils.pxi", line 79, in jnius.check_exception
jnius.JavaException: JVM exception occurred: org/apache/lucene/search/Query has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 java.lang.UnsupportedClassVersionError

I both try the java8 and java11. But neither can help to solve this.

could you try install the java environment with
conda install -c conda-forge openjdk=11
the above error comes from the pyserini dependency

Thanks for your help. Actually, I have installed the oracle jdk11. Is the version leads to the mistake?

If I type java --version in a shell, it says:
