Help with error when using PluginsWrapper() in pipeline

[zil...@gmail.com]

I have the following line in my pipeline to get the currently installed plugins.

def plugins = jenkins.model.Jenkins.instance.getPluginManager().getPlugins()

and it dumps the following. Any ideas why? I can run the code in the Scripts console.

an exception which occurred: in field com.cloudbees.groovy.cps.impl.BlockScopeEnv.locals in object com.cloudbees.groovy.cps.impl.BlockScopeEnv@2fa84c51 in field

This works just as well (posted on a thread here), and no dumps.

 def plugins = Jenkins.instance.pluginManager.plugins.findAll { !(it.shortName in ['job-dsl', 'structs']) }.collect { "${it.shortName}:${it.version}" }

Hi,

We can read "doWriteObject(BlockMarshaller.java:65)" 
We then can suppose plugins are not serializable object.

So, try to encapsulate your code in a groovy function, with the annotation @NonCPS
