c# - Unity gradle 构建失败

Question

我无法在 Unity 中构建另一个 APK。总是同样的错误。

CommandInvokationFailure: Gradle build failed. 
C:/Program Files/Java/jdk1.8.0_171\bin\java.exe -classpath "C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-4.0.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx2048m" "assembleRelease"

stderr[

我的设置和我尝试过的事情:

JDK 1.8 版

SDK 构建工具版本 25

我试图将“-dontwarn com.google.vr.ndk.base.DaydreamApi”复制到一个proguard文件中(在某处看到这种类型的解决方案)

从 gradle 构建切换到内部构建(因为内部构建出现不同的错误)

重新安装所有并重新启动我的计算机:D

在构建工具更新后，我的 Unity 构建也遇到了同样的问题，因此您可能也只需要更新它们即可。

正如错误消息中所说，您需要使用 android studio 接受 TOS
You have not accepted the license agreements of the following SDK components: [Android SDK Build-Tools 27.0.1]. Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.

Install Android studio在您的 PC 上(如果您还没有的话)

运行其 SDK 管理器(配置 > SDK 管理器 > SDK 工具)

如果 Android SDK 构建工具显示“未安装”，请单击它旁边的复选框进行安装。

如果显示“更新可用”，请单击旁边带有“-”的复选框，以显示“✓”

点击申请，并接受协议(protocol)。

这就是为我解决的问题，希望这也对你有用!
