我正在将 Grails 3.3.16 应用程序更新到 Grails 5.3.2。当我 grails run-app 时，我遇到了一个奇怪的异常，看不到源代码在我的代码中，并且无法在线找到解决方案。
希望有人遇到类似的问题，并能提供一些关于此错误的来源。
更新：我认为这里有一个双重问题：1.似乎我正在使用的一个配置已被弃用，2.当 Grails 报告弃用时，它使用了 Grails 5 中不存在的类，所以我明白了错误而不是我需要更改的配置的错误。也许其他人可以有更好的诊断。如果是这样，除了我的配置错误之外，Grails 5 中还存在一个错误。

我遇到了同样的问题，基本上我的依赖项之一是添加：
+--- org.grails:grails-datastore-rest-client:5.0.1.RELEASE
| +--- org.codehaus.groovy:groovy:2.4.5 -> 2.5.14
| +--- commons-codec:commons-codec:1.5 -> 1.13
| +--- org.grails:grails-plugin-converters:3.0.12
导致了这个问题。你可以调用
gradlew dependencies当我删除依赖转换器版本时，版本升至 4.0.1 并且项目开始了
