我发表了以下评论:
./gradlew app:installDebug
只是遇到了日志:
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine java version from '11.0.2'.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

我的…/ gradle /包装/ gradle-wrapper。properties包含以下内容，包括distributionUrl=…/gradle-4.1-rc-1-all.zip:
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip
以我为例，我试图为一个旧的Unity 3D项目构建和获得APK(这样我就可以在我的Android手机上玩游戏)。我使用的是最新的Android Studio版本，我可以通过Android Studio的SDK管理器下载所有SDK包。SDK包的位置
C:/Users/Onat/AppData/Local/Android/Sdk
我得到的错误消息是一样的，除了JDK (Java开发工具包)版本“JDK -12.0.2”。JDK位于
C:\Program Files\Java\jdk-12.0.2
Windows中的环境变量为JAVA_HOME: C:\Program Files\Java\jdk-12.0.2
经过3个小时的研究，我发现Unity不支持JDK 10。我的建议是:
Uninstall unwanted JDK if you have one installed already.
Head here
Login to/Open a Oracle account if not already logged in.
Download the older but functional JDK 8 for your computer set-up(32 bit/64 bit, Windows/Linux etc.)
Install the JDK. Remember the installation path.
If you are using Windows, Open Environment Variables and change Java Path via Right click My Computer/This PC>Properties>Advanced System Settings>Environment Variables>New>Variable Name: JAVA_HOME>Variable Value: [YOUR JDK Path, Mine was "C:\Program Files\Java\jdk1.8.0_221"]
In Unity 3D, press Edit > Preferences > External Tools and fill in the JDK path (Mine was "C:\Program Files\Java\jdk1.8.0_221").
Also, in the same pop-up, edit SDK Path. (Get it from Android Studio > SDK Manager > Android SDK > Android SDK Location.)
If needed, restart your computer for changes to take effect.
我在Ubuntu 18.04.3 LTS中遇到了同样的问题。在我的例子中，apt安装了gradle 4.4.1版本。已经安装的java版本是11.0.4
我得到的构建消息是
Could not determine java version from '11.0.4'.
当时，大多数在线文档都引用了gradle 5.6版本，所以我做了以下工作:
sudo add-apt-repository ppa:cwchien/gradle
sudo apt update
sudo apt upgrade gradle
然后我重复项目初始化(使用gradle初始化默认值)。之后，./gradlew构建可以正常工作。
我后来读到一个评论，关于java -version输出格式的改变，导致gradle崩溃，这在后来的gradle版本中得到了修复。
