我下载并安装了:

• JDK(jdk-9.0.1_osx-x64_bin.dmg从Oracle)在这里
• Android的SDK( sdk-tools-darwin-3859397.zip)从谷歌在这里.

配置PATH变量后,我尝试运行sdkmanager,它取代了android管理SDK组件的命令.但是,它失败了,如下所示:

$ sdkmanager --list
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema

    at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:496)
    ... 5 more

这是Java版本:

$ java -version
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

有没有人知道如何修复它而不回到Java 8？

相关问题

• 无法安装android-sdk
  • 这篇文章提出了类似的问题.但是,帖子已经关闭,唯一的答案就是回到Java 8.

我在我的React-Native项目中遇到了一个问题,该问题早先工作得很好,但突然间它停止了工作.每当我使用命令时:

react-native run-android

我收到一个错误:

找不到Android项目.也许首先运行react-native android？

我试过跑:

react-native android

但它说:

Unrecognized command 'android' Run react-native --help to see list of all available commands

尝试后:

D:\ProjectRoot\ReactNativeProjects\AwesomeProject>react-native eject

返回的错误是:

在D:\ ProjectRoot\ReactNativeProjects\AwesomeProject \node_modules(48ms)中扫描符号链接的文件夹name必须在app.json配置文件中定义应用程序才能定义项目名称.它不得包含任何空格或破折号.

这是app.json文件:

    "slug": "AwesomeProject",
