Hello, I'm using ABCL through Emacs with Slime and I'm having trouble setting bash environment variables needed for Maven to work. Here's what I have in my ~/.emacs file: (setq slime-lisp-implementations       '((abcl ("/usr/bin/java" "-jar"                "/path/to/abcl-bin-1.8.0/abcl.jar"                "/path/to/abcl-bin-1.8.0/abcl-contrib.jar"                "-Xmx6g")               :coding-system utf-8-unix               :env ("JAVA_HOME=/path/to/jdk-12/"                     "PATH=/opt/apache-maven-3.8.3/bin:$PATH")))) Problem is, the $JAVA_HOME and $PATH variables are not set for the ABCL process despite putting them here. The environment variables do work with other CL implementations. When I set them in SBCL, for example, I can run (uiop:run-program "echo $PATH" ...) and see the extension added to the path. This doesn't work in ABCL, and I need those extra environment variables set in order for Maven to work. Does anyone know a way to fix this? It works for other CLs, so I'm guessing something particular about ABCL is preventing the variables from being set. Thanks, Andrew
