You could do something like this, not tested so it might have some syntax and
logical errors.
- shell: ls /opt/groovy-${GROOVY_VERSION}/bin | fgrep -v .bat | grep -v
'^groovy$'
register: r
- set_fact:
GROOVY_ALT_SLAVES: '{% for item in r.stdout_lines %} --slave /usr/bin/{{
item }} {{ item }} /opt/groovy-{{ groovy_version }}/bin/{{ item }} {%- endfor
%}'
- command: update-alternatives --install /usr/bin/groovy groovy /opt/groovy-{{
groovy_version }}/bin/groovy 2000 {{ GROOVY_ALT_SLAVES }}
- command: update-alternatives --set groovy /opt/groovy-{{ groovy_version
}/bin/groovy
