grails - Grails插件创建: “No file extensions list found for path not being watched”

Question

我已经在Grails v2.4.3中使用grails create-plugin创建了Grails插件。

我已经将Tomcat插件添加到BuildConfig.groovy中，

build(":tomcat:7.0.55") {
    export = false
}

*编辑:我将这个项目放置为 on GitHub。

我从 grails run-app开始插件。插件加载完毕，我可以看到我创建的虚拟 Controller 。

我希望插件开发像常规的Grails开发一样工作。如果我运行它并进行更改，最好将其热重新加载而不用重新启动它。

如果进行任何更改，它不会更新正在运行的插件。相反，我收到错误消息，

编辑:在使用插件的任何项目中也会发生此错误，从而有效地破坏了开发模式。

谁有想法？有什么办法可以使这项工作吗？

我可以重现该问题，它看起来像个错误。我创建了一个错误报告:https://jira.grails.org/browse/GRAILS-11665。

我不清楚为什么它也会由安装的插件触发。
