Unity Gradle构建失败

Question

我无法在Unity中构建另一个APK。 总是相同的错误。

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[

我的设置和尝试过的事情：

• JDK版本1.8

• SDK构建工具版本25

• 我试图将“ -dontwarn com.google.vr.ndk.base.DaydreamApi”复制到proguard文件中（在某处看到了这种解决方案）

• 从gradle构建交换到内部构建（内部构建时会出现不同的错误）

• 重新安装所有并重新启动计算机：D

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

如错误消息中所述，您需要使用android studio接受服务条款

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.

• 在您的PC上安装Android Studio （如果尚未安装）
• 运行其SDK管理器（配置> SDK管理器> SDK工具）

• 如果Android SDK生成工具显示“未安装”，请单击其旁边的复选框以进行安装。

• 如果显示“更新可用”，请单击旁边带有“-”的复选框，以便显示“✓”

• 点击申请，并接受协议。

那就是为我解决的问题，希望它也对您有用！
