Eclipse - Groovy gets/sets appear as errors with Scala IDE installed

Question

I have the following Groovy class:

@ToString
@EqualsAndHashCode
class GitChangeset {
    String hash
    String commitMessage = ""
    String author = ""
    String authorEmail = ""
    String commitLink = ""
    String[] parents = []
    LocalDateTime time
}

I have both the Scala and Groovy eclipse plugins (Scala IDE 3.0.3 and Greclipse/Groovy-Eclipse 2.8.0) installed. I have the following snippet of Java code which compiles but does not appear to compile:

The file does not have a compilation error displayed (yes, build automatically is turned on):

If I remove the Scala IDE plugin, this now appears to compile correctly.
