Android Studio Gradle项目同步失败，原因是ExtensibleDynamicObject

在Android Studio中，我得到一个错误：

Gradle 'android' project refresh failed
    Error:Cause: org.gradle.api.internal.ExtensibleDynamicObject

建筑

当我应用实验插件时：

如以下文件所示：

我已经阅读了很多关于这个错误的文章，并遵循了给出的建议。这些建议通常建议添加赋值运算符“=”或“+=”，而其他建议则建议删除它们。不管怎样，到目前为止还没有任何建议修复了这个错误。其他人对修复此错误有什么建议吗

你不应该使用：

buildConfigFields.with{create（）{type“String”name“MAPBOX\u EVENTS\u USER\u AGENT\u BASE”value“myvalue”}

谷歌找到我，他们说他们放弃了实验性的gradle插件。如果是真的，他们应该标记文档，但我不认为他们会，直到他们有一个替换。克马克？等等，说真的？？天哪，我们有太多的代码依赖于Gradle实验插件！你不应该使用：

buildConfigFields.with{create（）{type“String”name“MAPBOX\u EVENTS\u USER\u AGENT\u BASE”value“myvalue”}

Google回复我，他们说他们放弃了实验性的gradle插件。如果是真的，他们应该标记文档，但我不认为他们会，直到他们有一个替换。克马克？等等，说真的？？天哪，我们有太多的代码依赖于Gradle实验插件！
