Converter implementation is not refreshed in IDEA

Using https://github.com/mapstruct/mapstruct-examples/tree/master/mapstruct-lombok as a reference, I tried to add a field to both Source and Target and then modified the test to cover the new field.

@Test
public void testMapping() {
    Source s = new Source();
    s.setTest( "5" );
    s.setField( "5" );

    Target t = Mappers.getMapper(SourceTargetMapper.class).toTarget( s );
    assertEquals( 5, (long) t.getTesting() );
    assertEquals( "5", t.getField() );
}

However this leads to the test to fail, being t.getField() still null.

Another relevant change I did (which I am not sure about) is to add mapstruct-processor to the compile configuration in build.gradle, ie: compile "org.mapstruct:mapstruct-jdk8:${mapstructVersion}", "org.mapstruct:mapstruct-processor:${mapstructVersion}", "org.projectlombok:lombok:${lombokVersion}" as per http://mapstruct.org/documentation/ide-support/

Also removing a field from both objects leads to an error, this time a java.lang.NoSuchMethodError.

Versions used:

• IDEA 2017.2.5 (with annotation processor manually enabled, no other customization)
• lombok 1.16.18 (instead of 1.16.14)

Usa l'esempio mapstruct-lombok e il relativo Source, Target e test come riproduzione; esamina prima build.gradle e la configurazione del processore di annotazioni di IDEA. Riproduci i casi di campo aggiunto e campo rimosso, quindi verifica che il convertitore generato rifletta le modifiche e che il test non segnali più null o NoSuchMethodError.
