I assume I'm making some strange error here, but I cannot figure out what
the error is.
I have a "changed_when" clause I've constructed that never seems to work.
However, if I take out the clause into its own debug statement, it seems to
work.
I have reproduced this with the following ansible:
- hosts: localhost
gather_facts: False
tasks:
- name: Update Jenkins-Jobs on Jenkins Master - docker container
command: |
echo "INFO:jenkins_jobs.cli.subcommand.update:Updating jobs in
['./jobs/'] ([])
INFO:root:Caching type parameters of parameters =
jenkins_jobs.modules.parameters:Parameters
INFO:root:Caching type builders of builders =
jenkins_jobs.modules.builders:Builders
INFO:jenkins_jobs.builder:Number of jobs generated: 1
INFO:jenkins_jobs.cli.subcommand.update:Number of jobs updated:
0
INFO:jenkins_jobs.builder:Number of views generated: 0
INFO:jenkins_jobs.cli.subcommand.update:Number of views
updated: 0
"
register: jjb_update
changed_when:
- ( jjb_update.stdout_lines | regex_replace('.*jobs
updated.\s+(\d+).*', '\1') != '0' )
- name: Number of jobs updated
debug:
msg: |
{{ jjb_update.stdout_lines | regex_replace('.*jobs
updated.\s+(\d+).*', '\1') }}
- name: Number of jobs updated equals 0?
debug:
msg: |
{{ jjb_update.stdout_lines | regex_replace('.*jobs
updated.\s+(\d+).*', '\1') == '0' }}
The output I get in both 2.8.6 and 2.9.1 is
TASK [Update Jenkins-Jobs on Jenkins Master - docker container]
************************************************************************************************************
changed: [localhost]
TASK [Number of jobs updated]
**********************************************************************************************************************************************
ok: [localhost] => {
"msg": "0\n"
}
TASK [Number of jobs updated equals 0?]
************************************************************************************************************************************
ok: [localhost] => {
"msg": "True\n"
}
If the output is 0 and the check is true, the first task should NOT show
changed.
