Hi,

on enhancing my entity classes with the (new) gradle plugin, i am getting this:

Unable to enhance class [/Users/ml/Development/java/projects/Netstorsys/build/classes/main/de/logentis/bwh/model/ConsignmentImport.class]

ConsignmentType is defined as following:

@Basic
@Enumerated(EnumType.STRING)
@Column(name = "constype")
ConsignmentType consignmentType;

Also for other enums. Is there something i miss regarding enums? I just switched from openjpa to Hibernate and with openjpa enhancement, i ve never had issues with Enums.

Thanks for infos.

Marc

Dont know if its a enum issue. I get also errors like this one:

Looks like a classpath issue which shouldnt be there because of gradle style convention behavior. Anyone there with Gradle Plugin experience?
