upgraded my unity from 2018.4.0 to 2019.3.7, I cannot build an apk now

我无法构建 apk，可能是库没有解析。以下是错误： CommandInvokationFailure：Gradle 构建失败。 /Applications/Unity/Hub/Editor/2019.3.7f1/PlaybackEngines/AndroidPlayer/OpenJDK/bin/java -classpath "/Applications/Unity/Hub/Editor/2019.3.7f1/PlaybackEngines/AndroidPlayer/Tools/gradle/lib/gradle-launcher-5.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"

Unity 正在尝试使用 gradle 6.0

编译 apk

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.

但它使用的是 gradle 5.1

CommandInvokationFailure: Gradle build failed. /Applications/Unity/Hub/Editor/2019.3.7f1/PlaybackEngines/AndroidPlayer/OpenJDK/bin/java -classpath "/Applications/Unity/Hub/Editor/2019.3.7f1/PlaybackEngines/AndroidPlayer/Tools/gradle/lib/gradle-launcher-5.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"

如果 android 模块有任何更新，请尝试查看 Unity HUB（在我的情况下，我需要安装它）

每当您更改 Unity 版本时，您都必须从 Unity Hub

重新下载并安装相应的 Android 模块

编辑，如果您没有看到 android 在您使用的 unity 版本下构建支持，您将不得不从 unity hub 再次下载 android 模块以适应您使用的 unity

如果没有单击三个点并添加模块，请检查 unity hub 中的机器人图标 -> android -> 单击可折叠菜单中 'android build support' 下的框

检查您是否受到旧 Hub 版本中出现的此问题的影响：https://issuetracker.unity3d.com/issues/android-editor-shows-that-the-android-ndk-is-not-recommended-even-though-it-is-installed-from-the-hub

您现在的 Hub 应该是 2.3.1 版。
