我刚刚从 play 2.2->play 2.3 迁移了我的应用程序，现在无法从 play 2.3->play 2.4 迁移它，尤其是使用 CommonsMailerPlugin。我收到以下运行时错误：

只需按照Play 2.4 Mailer的说明进行操作，然后从conf/play.plugins文件中删除对 Mailer 插件的引用。

就我而言，这是文件中唯一的一行，所以我删除了该文件。

据我所知，Play 2.4 有新版本的 Mailer 插件。并且有一个包更改：

com.typesafe.plugin.CommonsMailerPlugin - 2.4.1 版 play.api.libs.mailer.CommonsMailerPlugin - 2.3.x 版
