java - API 'variant.getJavaCompile()' 已过时

Question

我是 Kotlin 开发的新手，就在我将 Kotlin 添加到我的项目之后，出现了一些过时的问题。之前我们不得不将compile改为implementation时看到过类似的东西，但我真的不明白这是什么意思。

我收到的警告:

API 'variant.getJavaCompile()' is obsolete and has been replaced with 'variant.getJavaCompileProvider()'.
It will be removed at the end of 2019.

更新:这似乎是 kotlin 插件中的一个错误，其中提到了 in here

但是，使用新版本的 kotlin 插件(当 kotlin 开始使用新 API 时)可能会消除此处所述的错误:

https://github.com/JetBrains/kotlin/pull/1884/commits/1a17cb54a775ab3e55db66109cb12b7d54fbba6c

还有:https://github.com/JetBrains/kotlin/pull/1884

提交实际上是为了修复这个问题:

This commit does not change anything functionally, it is only to avoid the warning message, as reporter in https://issuetracker.google.com/116198439

在深入搜索代码后，看起来像 getJavaCompile()在您当前的 gradle(alpha11 版本)中已过时。但是，您使用的是 gradle 的 alpha 版本，我不建议这样做。

请尝试使用稳定版本，例如:

classpath 'com.android.tools.build:gradle:3.1.4'

然后我希望警告应该消失。
