Pattern: Unused private field
Issue: -
Checks for private fields that are not referenced within the same class. Note that the private modifier is not currently "respected" by Groovy code (i.e., Groovy can access private members within other classes).
By default, fields named serialVersionUID, and fields annotated with groovy.lang.Delegate are ignored. The rule has a property named ignoreFieldNames, which can be set to ignore other field names as well. For instance, to also ignore fields named 'fieldx', set the property to the 'fieldx, serialVersionUID'
| Property | Description | Default Value |
|---|---|---|
| ignoreFieldNames | Specifies one or more (comma-separated) field names that should be ignored (i.e., that should not cause a rule violation). The names may optionally contain wildcards (*,?). | serialVersionUID |
Known limitations:
- Does not recognize field access when field name is a GString (e.g.
this."$fieldName") - Does not recognize access of private field of another instance (i.e. other than
this)
