When running ./ath-container.sh it fails with:

curl: (22) The requested URL returned error: 404 Not Found
The command '/bin/sh -c curl -ffSLO https://www.apache.org/dist/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz &&     tar -xvzf apache-maven-3.6.1-bin.tar.gz -C /opt/ &&     mv /opt/apache-maven-* /opt/maven' returned a non-zero code: 22
./ath-container.sh: Error 22 on line 13: docker build --build-arg=uid="$uid" --build-arg=gid="$gid" "$DIR/src/main/resources/ath-container" -t "$tag"

The reason is that https://www.apache.org/dist/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz is no longer available. So any new fresh installation of ATH will fail.

I will update the URL to use the archive repo:

https://archive.apache.org/dist/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz

Although we can use the 3.6.3 binaries, I don't want to take any risk as I have no time to check whether the new version may imply any problem (don't seem so but who knows)

If someone wants to update and check the 3.6.3 version, I think it is best to use:

https://archive.apache.org/dist/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz 

Instead of:

https://www.apache.org/dist/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

To avoid the same issue in the future.
