    Description

      com/foo/Person.groovy
      package com.foo
      
      @groovy.transform.builder.Builder
      class Person {
          String name
      }
      

      1.

      Main.groovy
      import com.foo.Person
      
      class Main {
          static void main(String[] args) {
              Person.PersonBuilder pb = Person.builder() 
              println(pb.build())
          }
      }
      

      Trying to use it without a static import yields unable to resolve class Person.PersonBuilder, which is another issue.

      2. Let's add a static import

      Main.groovy
      import com.foo.Person
      import static com.foo.Person.PersonBuilder
      
      class Main {
          static void main(String[] args) {
              PersonBuilder pb = Person.builder()
              println(pb.build())
          }
      }
      

      The code compiles, but fails with java.lang.NoClassDefFoundError: PersonBuilder when run.

      3. Let's add @CompileStatic

      Main.groovy
      import com.foo.Person
      import static com.foo.Person.PersonBuilder
      import groovy.transform.CompileStatic
      
      @CompileStatic
      class Main {
          static void main(String[] args) {
              PersonBuilder pb = Person.builder()
              println(pb.build())
          }
      }
      

      Compilation fails with:
      Cannot assign value of type com.foo.Person$PersonBuilder to variable of type PersonBuilder and Cannot find matching method PersonBuilder#build()
