    This class is an alternate to JavaAppPackaging designed to support the ash shell.

    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 $@
