android - Unity Gradle build 找不到 Build Tools 修订版 28.0.0

Question

几天来我一直在为这个问题苦苦挣扎，我似乎找不到解决它的方法，这里是完整的错误:

CommandInvokationFailure: Gradle build failed. 
C:/Program Files/Java/jdk1.8.0_131\bin\java.exe -classpath "C:\Program Files\Unity2017.2\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-2.14.jar" org.gradle.launcher.GradleMain "assembleDebug"

stderr[

出于某种原因，它一直将其 buildToolsVersion 覆盖为“'28.0.0'”，即使我专门将build设置设置为此:

我还将我自己的 gradle.build 文件添加到 Plugin/Android，这是同一个文件，但不同的 BuildToolsVersion 设置为 27.0.0，然而，位于项目内 Temp 文件夹中的 build.gradle 文件仍在重置自身到“28”，

我还将我自己的 gradle.build 文件添加到 Plugin/Android，这是同一个文件，但不同的 BuildToolsVersion 设置为 27.0.0，然而，位于项目内 Temp 文件夹中的 build.gradle 文件仍在重置自身到“28”，最后是我的 SDK 管理器的一些截图:

Android (P) 的部分安装是因为这个(我不必全部安装它们不是吗？):

SDK 工具:

更新:从构建工具中删除 28.0.0-rc1 后，build.gradle 开始构建版本 27，但现在出现新错误:

Answer 1

AWrightIV's answer把我带到了那里。但对我来说，解决方案没那么复杂。当您在播放器设置中打开“使用自定义 gradle 文件”并更改 buildToolsVersion 行时，我生成了一个统一创建的 mainTemplate.gradle 文件。

Assets/Plugins/Android/mainTemplate.gradle 中的原始行:

buildToolsVersion '**BUILDTOOLS**'

新:

buildToolsVersion '27'
