安装android-sdk: "java.lang "失败。NoClassDefFoundError: javax / xml /绑定/注释/ XmlSchema”

当安装android sdk工具时，会产生以下错误:

java.lang.NoClassDefFoundError: javax / xml /绑定/注释/ XmlSchema

为什么会发生这种情况，如何解决?

调试输出:

$ java --version
java 9
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)
$ brew cask install android-sdk
==> Caveats
We will install android-sdk-tools, platform-tools, and build-tools for you.
You can control android sdk packages via the sdkmanager command.
You may want to add to your profile:
  'export ANDROID_SDK_ROOT=/usr/local/share/android-sdk'

This operation may take up to 10 minutes depending on your internet connection.
Please, be patient.

当前回答

我在跑步时也遇到了同样的问题:

$ /Users/<username>/Library/Android/sdk/tools/bin/sdkmanager "platforms;android-28" "build-tools;28.0.3"_

我解的是

$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home    

$ ls /Library/Java/JavaVirtualMachines/

jdk-11.0.1.jdk      
jdk1.8.0_202.jdk

将Java改为使用1.8

$ export JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home'

然后，相同的命令可以正常运行

$ /Users/<username>/Library/Android/sdk/tools/bin/sdkmanager "platforms;android-28" "build-tools;28.0.3"

其他回答

在Mac/Linux上使用以下命令:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

适用于JDK 9和10，无需修补任何脚本(sdkmanager, avdmanager)。

Java 11参见:https://stackoverflow.com/a/51644855/798165

当使用Linux时，一个简单的选项是安装JDK版本8，然后选择它作为默认使用:

sudo update-alternatives --config java

TLDR;试着在OSX上设置JAVA_HOME工作得很好

export JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

从AdoptOpenJDK安装JDKs 8 (LTS):

# brew tap adoptopenjdk/openjdk

brew cask install adoptopenjdk/openjdk/adoptopenjdk8

我找到了两个对我有用的答案，而不需要卸载创建-反应-app所需的JDK 10(或9)。JDK 9和JDK 10都不兼容android-sdk !

Siu Ching Pong -飞鸟健二-建议修改sdkmanager脚本，替换这一行:

DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME"'

DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME" -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

注意，这个mod在更新sdkmanager时会被覆盖。查看他的帖子和他的链接，了解更多细节。这个解决方案也是这个github问题线程中提到的解决方案之一。

German的帖子指出了冲突的来源，并提出了不会被更新覆盖的修复方案。他建议重命名/Library/Java/JavaVirtualMachines/Info。plist是一种将它与寻找系统中Java的最高版本的脚本隔离的方法。这样，JDK 8将作为默认值返回。显式引用JDK 10，或将其设置为$JAVA_HOME，您可以在需要时使用JDK 10，而不是默认值。详情见他的文章。
