Keegan Witt commented on GROOVY-7906:
-------------------------------------
I'm working on creating some official Groovy Docker images and encountered the
same issue. It'd be less intrusive to use Bash just for Groovy, while not
affecting the rest of the environment. One way is to just change the shebangs:
{code}
RUN set -ex \
&& sed -i -e "s|#!/bin/sh|#!/bin/bash|" /opt/groovy/bin/grape \
&& sed -i -e "s|#!/bin/sh|#!/bin/bash|" /opt/groovy/bin/groovy \
&& sed -i -e "s|#!/bin/sh|#!/bin/bash|" /opt/groovy/bin/groovyc \
&& sed -i -e "s|#!/bin/sh|#!/bin/bash|" /opt/groovy/bin/groovyConsole \
&& sed -i -e "s|#!/bin/sh|#!/bin/bash|" /opt/groovy/bin/groovydoc \
&& sed -i -e "s|#!/bin/sh|#!/bin/bash|" /opt/groovy/bin/groovysh \
&& sed -i -e "s|#!/bin/sh|#!/bin/bash|" /opt/groovy/bin/java2groovy
{code}
I mentioned the idea on the related mailing list
