我正在使用 grails 2.4.2 版本。当我运行命令 run-app 时，应用程序运行良好，Intellij 控制台中没有错误。当我运行命令 prod run-app 时，它也可以正常工作而不会出错。但是当我运行命令 run-war 时，会出现以下错误。我已经搜索过了，但没有解决方案适用于我的情况，或者我可能不理解。

这是我在 Intellij 控制台中的错误：

升级您的 Grails 版本可能会解决您的问题。升级程序

  1. 项目 -> 清理

  2. application.properties -> 更改 app.grails.version = (新版本)

  3. 您的项目 -> 属性 -> Grails -> 将 grails 安装更改为新的 grails 版本。

  4. 您的项目 -> Grails 工具 -> 刷新依赖项

  5. 运行你的项目

或者看看Grails 升级

在 buildConfig.groovy 中添加此代码

inherits("global") {
        excludes 'grails-plugin-log4j'
    }
