Setting Up Stand-alone LanguageTool in Docker container - node.js

Question

Im trying to setup LanguageTool as a standalone server as a Docker Container. So what I did is download the standalone system provided at -> https://languagetool.org/download/LanguageTool-stable.zip and put it in my project. I setup the docker-compose.yml file like so
version: '3'
services:
grammar:
build: ./services/grammar
image: dev/grammar:1
restart: always
container_name: dev.grammar
ports:
- "8130:8130"
And I created the dockerfile inside the LanguageTool folder like so
FROM ubuntu:18.04
WORKDIR /tmp
RUN apt-get update
RUN apt-get install unzip
ADD https://languagetool.org/download/LanguageTool-stable.zip /tmp/LanguageTool-stable.zip
#RUN apt-get install -y unzip
RUN unzip /tmp/LanguageTool-stable.zip
RUN mv /tmp/LanguageTool-5.7 /usr/languagetool
CMD ["java", "-jar", "languagetool-server.jar", "--port", "8130", "--public", "--allow-origin", "'*'" ]
EXPOSE 8130
I have actually tried many iterations of the dockerfile like another example here
FROM debian:stretch
RUN set -ex \
&& mkdir -p /uploads /etc/apt/sources.list.d /var/cache/apt/archives/ \
&& export DEBIAN_FRONTEND=noninteractive \
&& apt-get clean \
&& apt-get update -y \
&& apt-get install -y \
bash \
curl \
openjdk-8-jre-headless \
unzip \
libhunspell-1.4-0 \
hunspell-de-at
ENV VERSION 5.7
COPY LanguageTool-$VERSION.zip /LanguageTool-$VERSION.zip
RUN unzip LanguageTool-$VERSION.zip \
&& rm LanguageTool-$VERSION.zip
WORKDIR /LanguageTool-$VERSION
CMD ["java", "-cp", "languagetool-server.jar", "org.languagetool.server.HTTPServer", "--port", "8130", "--public", "--allow-origin", "'*'" ]
EXPOSE 8130
But none of them seems to work. Please let me know what I am doing wrong here. Thanks in advance !!
Edit: Here is what my file/folder structure looks like here

I found the solution. Had to tinker around some configurations but I finally got it working. here is the dockerconfig file that worked for me.
FROM debian:stretch
RUN set -ex \
&& mkdir -p /uploads /etc/apt/sources.list.d /var/cache/apt/archives/ \
&& export DEBIAN_FRONTEND=noninteractive \
&& apt-get clean \
&& apt-get update -y \
&& apt-get install -y \
bash \
curl \
openjdk-8-jre-headless \
unzip \
libhunspell-1.4-0 \
hunspell-de-at
ENV VERSION 5.1
COPY LanguageTool-$VERSION.zip /LanguageTool-$VERSION.zip
RUN unzip LanguageTool-$VERSION.zip \
&& rm LanguageTool-$VERSION.zip
WORKDIR /LanguageTool-$VERSION
CMD ["java", "-cp", "languagetool-server.jar", "org.languagetool.server.HTTPServer", "--port", "8130", "--public", "--allow-origin", "'*'" ]
EXPOSE 8130
