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)

Utilisez l’exemple mapstruct-lombok ainsi que son Source, Target et test comme reproduction ; inspectez d’abord build.gradle et la configuration du processeur d’annotations d’IDEA. Reproduisez les cas d’ajout et de suppression de champ, puis vérifiez que le convertisseur généré reflète les changements et que le test ne signale plus null ni NoSuchMethodError.
