---------------------------------

             Summary: @groovy.transform.builder.Builder should generate 
@Generated annotations for build(), builder() and setter methods
                 Key: GROOVY-9054
                 URL: https://issues.apache.org/jira/browse/GROOVY-9054
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 2.5.6
            Reporter: Jan Wloka


Using the @groovy.transform.builder.Builder with SimpleStrategy yields the 
following problems.

Groovy input
{code}
@groovy.transform.builder.Builder
class GroovyBuilderClassTarget {

    @groovy.transform.builder.Builder(builderStrategy= SimpleStrategy)
    class Person {
        String first
        String last
        Integer born
    }
    static void main(String[] args) {
        new GroovyBuilderClassTarget()
    }
}
{code}

Groovy output:
{code}
@Builder
public class GroovyBuilderClassTarget implements GroovyObject {
    @Generated
    public GroovyBuilderClassTarget() {
        CallSite[] var1 = $getCallSiteArray();
        super();
        MetaClass var2 = this.$getStaticMetaClass();
        this.metaClass = var2;
    }

    public static void main(String... args) {
        CallSite[] var1 = $getCallSiteArray();
        var1[0].callConstructor(GroovyBuilderClassTarget.class);
    }

    @Generated
    public static GroovyBuilderClassTarget.GroovyBuilderClassTargetBuilder 
builder() {
        CallSite[] var0 = $getCallSiteArray();
        return 
(GroovyBuilderClassTarget.GroovyBuilderClassTargetBuilder)ScriptBytecodeAdapter.castToType(var0[1].callConstructor(GroovyBuilderClassTarget.GroovyBuilderClassTargetBuilder.class),
 GroovyBuilderClassTarget.GroovyBuilderClassTargetBuilder.class);
    }

    @Builder(
        builderStrategy = SimpleStrategy.class
    )
    public class Person implements GroovyObject {
        private String first;
        private String last;
        private Integer born;

        @Generated
        public Person() {
            CallSite[] var2 = $getCallSiteArray();
            super();
            MetaClass var4 = this.$getStaticMetaClass();
            this.metaClass = var4;
        }

        @Generated
        public GroovyBuilderClassTarget.Person setFirst(String first) {
            CallSite[] var2 = $getCallSiteArray();
            this.first = first;
            return this;
        }
        @Generated
        public GroovyBuilderClassTarget.Person setLast(String last) {
            CallSite[] var2 = $getCallSiteArray();
            this.last = last;
            return this;
        }

        @Generated
        public GroovyBuilderClassTarget.Person setBorn(Integer born) {
            CallSite[] var2 = $getCallSiteArray();
            this.born = born;
            return this;
        }

        @Generated
        public String getFirst() {
            return this.first;
        }

        @Generated
        public String getLast() {
            return this.last;
        }

        @Generated
        public Integer getBorn() {
            return this.born;
        }
    }

    @Generated
    public static class GroovyBuilderClassTargetBuilder implements GroovyObject 
{
        @Generated
        public GroovyBuilderClassTargetBuilder() {
            CallSite[] var1 = $getCallSiteArray();
            super();
            MetaClass var2 = this.$getStaticMetaClass();
            this.metaClass = var2;
        }

        @Generated
        public GroovyBuilderClassTarget build() {
            CallSite[] var1 = $getCallSiteArray();
            GroovyBuilderClassTarget _theGroovyBuilderClassTarget = 
(GroovyBuilderClassTarget)ScriptBytecodeAdapter.castToType(var1[0].callConstructor(GroovyBuilderClassTarget.class),
 GroovyBuilderClassTarget.class);
            return _theGroovyBuilderClassTarget;
        }
    }
}
{code}

I'd expect the following methods to have an @Generated annotation:
public static GroovyBuilderClassTarget.GroovyBuilderClassTargetBuilder builder()
public GroovyBuilderClassTarget.Person setFirst(String first)
public GroovyBuilderClassTarget.Person setLast(String last)
public GroovyBuilderClassTarget.Person setBorn(Integer born)
public GroovyBuilderClassTarget build()

Found during Hackergarten Zurich.
