执行
react-native run-android
gradle版本： 4.1
jdk：9.0.1
报错：
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...FAILURE: Build failed with an exception.
* What went wrong:
Could not determine java version from '9.0.1'.
解决方法：
升级到最新版本Gradle 4.3-rc-2可以解决。
找到项目的gradle-wrapper.properties文件，路径如下
PROJECT_PATH/android/gradle/wrapper/gradle-wrapper.properties
distributionUrl修改如下：
distributionUrl=https\://services.gradle.org/distributions/gradle-4.3-rc-2-all.zip
