 What this does:
-- Runs `./gradlew :lyng:installJvmDist` to build the JVM app distribution to `lyng/build/install/lyng-jvm`.
-- Copies the distribution under `~/bin/jlyng-jvm`.
+- Runs `./gradlew :lyng:jvmDistZip` to build the JVM app distribution archive at `lyng/build/distributions/lyng-jvm.zip`.
+- Copies the archive to `distributables/lyng-jvm.zip`.
+- Unpacks that distribution under `~/bin/jlyng-jvm`.
 - Creates a symlink `~/bin/jlyng` pointing to the launcher script.
