--- Comment #1 from Igal Sapir <isa...@apache.org> --- I actually just got that same error a couple of hours ago building 9.0.13-dev using Java 1.8.0_172 and Ant 1.9.7 on Windows. I upgraded to ant 1.10.5 and it solved the issue for me. Are you sure that the correct version of Ant is on the path? Can you confirm by running the command: ant -version ? -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
