Affects PMD Version: 6.5.0, 6.6.0
Description: When invoking run.sh I receive the error /usr/local/Cellar/pmd/6.5.0/libexec/bin/run.sh: line 82: [: : integer expression expected
I believe the direct cause is that the $java_ver variable is not properly set, on line 79 of run.sh
Replacing line 79 with java_var=100 fixes the error message.
I encountered this with 6.5.0 installed via Homebrew, and also with 6.6.0 which I built using Maven.
This is the output produced by java -version on my machine. I am using the Java installed by Homebrew.
