Pattern: Use of deprecated groovy.lang.Immutable

Issue: -

Description

The groovy.lang.Immutable annotation has been deprecated and replaced by groovy.transform.Immutable. Do not use the Immutable in groovy.lang.

Example of violations:

@Immutable                          // Violation (no import means groovy.lang.Immutable)
class Person { }

@groovy.lang.Immutable              // Violation
class Person { }

import groovy.lang.Immutable as Imtl
@Imtl                               // Violation
class Person { }

Example of valid use of @Immutable:

@groovy.transform.Immutable                 // OK
class Person { }

import groovy.transform.Immutable           // OK
@Immutable
class Person { }

import groovy.transform.*
@Immutable                                  // OK
class Person { }

import groovy.transform.Immutable as Imtl
@Imtl                                       // OK
class Person { }

@javax.annotation.concurrent.Immutable      // OK
class SomeClass { }
