Description

I'm unable to build Cassandra from source by running ant in the root directory on Windows 10, using AdoptOpenJDK 8 and Ant 1.10.11. The build fails with the following:

generate-jflex-java:

I've also tried doing it through Windows Subsystem for Linux (WSL 2) with the same versions of Java and Ant. I get the same error.

My environment:

• Windows 10 Pro (Version 20H2, build 19042.1110)
• 
  OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_292-b10)
• 
  Apache Ant(TM) version 1.10.11 compiled on July 10 2021

Note: I should probably mention that I'm new to Cassandra and I've never been able to build it before. I'm trying to run an initial build before I run the script to generate Intellij IDEA files (since generate-jflex-java is executed during the generate-idea-files task, it fails there with the error above too). If I'm doing something wrong, please let me know.
