What are you trying to do?

I think you're trying #227 which isn't supported yet

Hi I am not able generate YAML (not in container)

Command I use java -jar jenkins-plugin-manager-*.jar --war jenkins.war -d testing --output yaml

Note:- testing is a directory in which I installed plugins
Steps I follow are
Step 1 Install plugins in testing directory: java -jar jenkins-plugin-manager-*.jar --war jenkins.war --plugin-file plugins.txt --plugins delivery-pipeline-plugin:1.3.2 deployit-plugin -d testing
Step 2 Generate YAML:- java -jar jenkins-plugin-manager-*.jar --war jenkins.war -d testing --output yaml

I have an existing plugins.txt file and an existing directory of plugins called ref/plugins. It generates yaml output when I use the command:

$ java -jar jenkins-plugin-manager-*.jar --jenkins-version 2.332.2 --plugin-download-directory ref/plugins \
    --plugin-file plugins.txt --no-download --available-updates --output yaml

If I remove the --plugin-file plugins.txt argument, the output is empty. I believe that running without providing --plugin-file is what is requested in #227 and that is not yet implemented.

See the instructions on jenkins.io to generate a new plugins.txt file from a running Jenkins installation. It is done from the groovy script console in Jenkins with the command:

Jenkins.instance.pluginManager.plugins
    .collect()
    .sort { it.getShortName() }
    .each {
        plugin -> println("${plugin.getShortName()}:${plugin.getVersion()}")
    }
return
