Question

应用程序从grails 2.0.4升级到2.5.6

运行grails war或grails run-app时，会失败并显示消息

| Environment set to development.....
| Packaging Grails application.....
| Error Error executing script RunApp: grails/plugins/Plugin

grails compile运行正常。 grails clean和clean-all无效。删除scriptCache甚至整个%HOME%\.grails目录都没有效果。

在主应用程序中遇到错误后，新的helloworld应用程序在同一环境中编译并运行良好。

我知道插件已更改。导入或其他配置上是否存在可能影响此问题的内容？

Answer 1

grails.plugins.Plugin不是Grails 2.5.6中的类，而是grails 3中的类（通过检查其API http://docs.grails.org/2.5.6/api/ vs http://docs.grails.org/latest/api/grails/plugins/Plugin.html来证明）。

看来你已经以某种方式将Grails 3插件插入到Grails 2.5.6项目中。您必须通过检查BuildConfig.groovy并更改有问题的插件的版本或删除它们来解决这个问题。

grails 2.5.6执行脚本RunApp时出错
