I am an ABCL user, but by no means an expert. I just unpacked the source zip file and tried to compile it without success. I am using Java 14.0.1 and Ant 1.9.6. The resulting output is attached.
buildfile: C:\Users\baryza__Library\Armed_Bear_Lisp\abcl-src-1.6.1\build.xml

abcl.compile.java: [javac] Compiling 271 source files to C:\Users\baryza__Library\Armed_Bear_Lisp\abcl-src-1.6.1\build\classes [javac] warning: [options] bootstrap class path not set in conjunction with -source 6 [javac] error: Source option 6 is no longer supported. Use 7 or later. [javac] error: Target option 6 is no longer supported. Use 7 or later.
For Java 14, we need to tell the compiler to target the right source compatibility.
There is a script in `ci/create-abcl-properties.bash` that works with Bash to do configuration, but I see from your logs that you are running under Windows.
So do the steps manually:
1. copy `abcl.properties.in` to `abcl.properties`
2. Change the line with `abcl.javac.source` to read
abcl.javac.source=1.8
Then you should be able to compile (or at least get past this error).
Not sure what is going on with the mailing list…
