java - Grails3:AuthRoleController中的java.lang.Boolean hasErrors()的返回类型与grails.artefact.Controller中的 boolean 值不兼容。

Question

我已将我的应用程序从grails 2.5升级到grails 3.3.11。我已经按照所有步骤进行了，一切似乎都很好，但是当我运行该应用程序时。我遇到这个错误:
启动失败:
/home/server-dev/Documents/dev_repo/tms/grails-app/controllers/org/niport/auth/AuthRoleController.groovy:-1:org.niport.auth中java.lang.Boolean hasErrors()的返回类型.AuthRoleController与grails.artefact.Controller中的boolean不兼容
。在[-1:-1] @行-1的第-1列。
1个错误
失败:生成失败，发生异常。

出了什么问题:
任务':compileGroovy'的执行失败。

Compilation failed; see the compiler error output for details.

任何想法或帮助都会有所帮助，非常感谢

class AuthRoleController implements Validateable

没有充分的理由让 Controller 实现 Validateable特性，这样做会引起问题。
问题是，您将获得2个名为 hasErrors的方法，一种方法来自 https://github.com/grails/grails-core/blob/1979b62d0ef9ebbaa547c8744263376557a10459/grails-plugin-validation/src/main/groovy/grails/validation/Validateable.groovy#L58，一种方法来自 https://github.com/grails/grails-core/blob/1979b62d0ef9ebbaa547c8744263376557a10459/grails-plugin-controllers/src/main/groovy/grails/artefact/Controller.groovy#L123，它们具有不同的返回类型。
