PluginWrapper (Jenkins core 2.155 API)

java.lang.Object
- hudson.PluginWrapper

All Implemented Interfaces:

ModelObject, Comparable<PluginWrapper>
```
@ExportedBean
public class PluginWrapper
extends Object
implements Comparable<PluginWrapper>, ModelObject
```
Represents a Jenkins plug-in and associated control information for Jenkins to control Plugin.
A plug-in is packaged into a jar file whose extension is ".jpi" (or ".hpi" for backward compatibility), A plugin needs to have a special manifest entry to identify what it is.
At the runtime, a plugin has two distinct state axis.
1. Enabled/Disabled. If enabled, Jenkins is going to use it next time Jenkins runs. Otherwise the next run will ignore it.
2. Activated/Deactivated. If activated, that means Jenkins is using the plugin in this session. Otherwise it's not.
For example, an activated but disabled plugin is still running but the next time it won't.
