Error /opt/eclipse_install_tools/install_eclipse.sh: not found

[wcomnisky]

Using the master branch and trying to build form the Dockerfile I'm getting the following error:

/bin/sh: 1: /opt/eclipse_install_tools/install_eclipse.sh: not found
The command '/bin/sh -c $ECLIPSE_INST_TOOL -y -t $ECLIPSE_BASE_DIR -p egit' returned a non-zero code: 127

So I tried to run the install_eclipse.sh to see what was going on and I got this:

$ cd eclipse_install_tools && chmod +x install_eclipse.sh && ./install_eclipse.sh
bash: ./install_eclipse.sh: /bin/bash^M: bad interpreter: No such file or directory

Complete log for the docker build command:

$ docker build -t docker-eclipse .
