@timja
@minesskylineGTR do you have a plugins.txt file or something?
I just downloaded the last release

I just downloaded the jenkins.war from https://www.jenkins.io/download
and pointed it at that

@minesskylineGTR
@timja ok, this is weird. i grabbed your command and with edits ran it (also made sure to unset any env vars to be sure) and i am still getting the same json parse error

@slide
can you wget/curl that same URL and see if there is valid data?
minesskylineGTR
@minesskylineGTR
which url, the update center url? @slide
hmmm... getting a 301 but it should follow redirects for the app i would imagine
curl'ing https://updates.jenkins.io/current/update-center.actual.json works
let me set that as a option for the UC

doing:

java -jar /plugin-management-cli-*.jar --list --jenkins-update-center https://updates.jenkins.io/current/update-center.actual.json

results in:

Alex Earl
@slide
Yes, I meant the update center URL
I opened https://updates.jenkins.io/update-center.actual.json in my browser and it worked fine for me
minesskylineGTR
@minesskylineGTR
yea, like i said https://updates.jenkins.io/update-center.actual.json redirects to https://updates.jenkins.io/current/update-center.actual.json
i can curl https://updates.jenkins.io/current/update-center.actual.json just fine from the jenkins box

so this looks better. but weird it's not listing anything that i have installed
(didn't have security certs installed for java to handle tls connection it seems)
minesskylineGTR
@minesskylineGTR
ah, i should have read the README better. using -d flag will overwrite the folder completely, even if there are plugins/files there. now jenkins wants to uninstall everything i have because set the -d flag to my plugins location.
Alex Earl
@slide
:+1:
minesskylineGTR
@minesskylineGTR
actually, the README does not say this about -d:
--plugin-download-directory or -d: (optional) Path to the directory in which to install plugins, which can also be set via the PLUGIN_DIR environment 
variable. Directory will be created if it does not exist. If no directory is entered, directory will default to C:\ProgramData\Jenkins\Reference\Plugins if 
detected OS is Windows, or /usr/share/jenkins/ref/plugins otherwise.
it should not delete if something already exists
Alex Earl
@slide
There was a discussion about that a long while ago, I think there was a conscious choice to do it that way, but I don't recall the full discussions
Tim Jacomb
@timja
good to see you got it working, it's expecting that you're listing all of your plugins, but that can be improved, I replied on the issue you raised

@timja yea, took some time but i thought i had it mostly resolved. for whatever reason --list does not work as expected. after reading the README i am not sure why it won't list the plugins i have installed. supplying -d with any other option just removes the contents of that directory so not sure what to do about that. i also seem to have continuous issues with the jar not following redirects for the update center. see below again

providing the full update center url gives the same error:

@timja w.r.t plugin installation manager, do we want to follow semver there?
https://github.com/jenkinsci/plugin-installation-manager-tool/releases/tag/plugin-management-parent-pom-1.1.2 could have been 1.2.0. Not a big deal, just wondering about the versioning schema for the future
Tim Jacomb
@timja
Yes that would be good
I think that was me using mvn -B :p
