JVM exception "has been compiled by a more recent version of the Java Runtime" error when importing pyserini #1814

Closed parraro closed 2 years ago

parraro commented 2 years ago

I get an error regarding the anserini classes being compiled with a newer version of Java. I tried changing my system's java to be java 8 to match the java runtime 52 required but the error remains.

I am trying to run the code on Pycharm.

As stated in our README: https://github.com/castorini/anserini#getting-started

You'll need Java 11 and Maven 3.3+ to build Anserini.

Thank you.

Using the openjdk 11 resulted in the same error. I realized after your comment that I needed to install and use Oracle's jdk 11 for it to work.

Thank you for your help.
