docker - unable to access jarfile during docker run

Question

I am unable to resolve issue executing my run.sh file which invokes jar file within it. When i execute my run.sh file from my local, it works as expected.

docker file:

FROM maven:3.8.1-adoptopenjdk-11
WORKDIR /folder1
COPY folder1/ /folder1/
CMD ["/folder1/run.sh"] 

run.sh file which resides within folder1

#!/bin/sh
java -jar ".\test.jar" excel ".\\"
echo "Starting execution..."
read -t 5 -p "I am going to wait for 5 seconds only ..."

Commands executed:

docker build -t demo3 .

docker run -it -p 4044:4044 demo3

Error:

Unable to access jarfile .\test.jar
Starting execution...
