object AshScriptPlugin extends AutoPlugin

Java Application

This class is an alternate to JavaAppPackaging designed to support the ash shell. JavaAppPackaging generates bash-specific code that is not compatible with ash, a very stripped-down, lightweight shell used by popular micro base Docker images like BusyBox. The AshScriptPlugin will generate simple ash-compatible output.

Just like with JavaAppPackaging you can override the bash-template file by creating a src/templates directory and adding your own bash-template file. Actually this isn't a bad idea as the default bash-template file inherited from JavaAppPackaging has a lot of stuff you probably don't want/need in a highly-constrained environment like ash+BusyBox. Something much simpler will do, for example:

#!/usr/bin/env sh

realpath () { ( TARGET_FILE="$1"

cd "$(dirname "$TARGET_FILE")" TARGET_FILE=$(basename "$TARGET_FILE")

COUNT=0 while [ -L "$TARGET_FILE" -a $COUNT -lt 100 ] do TARGET_FILE=$(readlink "$TARGET_FILE") cd "$(dirname "$TARGET_FILE")" TARGET_FILE=$(basename "$TARGET_FILE") COUNT=$(($COUNT + 1)) done

if [ "$TARGET_FILE" == "." -o "$TARGET_FILE" == ".." ]; then cd "$TARGET_FILE" TARGET_FILEPATH= else TARGET_FILEPATH=/$TARGET_FILE fi

echo "$(pwd -P)/$TARGET_FILE" ) }

real_script_path="$(realpath "$0")" app_home="$(realpath "$(dirname "$real_script_path")")" lib_dir="$(realpath "${app_home}/../lib")"

${{template_declares}}

java -classpath $app_classpath $app_mainclass $@
