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

从Android命令行工具的最新版本(撰写本文时为2.1)开始，不再需要给sdkmanager打补丁，也不再需要降级到古老的Java版本。

只需更新SDK包，并将命令行工具切换到最新版本，即可跟踪新版本:

sdkmanager --update
sdkmanager 'cmdline-tools;latest'
sdkmanager --uninstall 'cmdline-tools;1.0'

如果sdkmanager的完整路径不在您的path中，您可能需要提供它，如果它显式地引用1.0工具，您可能需要在之后调整您的path。

今天早上我遇到了类似的问题(尝试使用Unity3D为Android构建)。我最终卸载了JDK9，并安装了Java SE Development Kit 8u144。

卸载java9 酿造tap自酿/桶酿版本安装java8 如果没有这个文件，点击~/.android/repositories.cfg #，下一步将发生错误 Brew install—cask android-sdk

当您的Android studio /jre使用不同版本的java时，您将收到此错误。要解决这个问题，只需将Android studio/jre设置为JAVA_HOME。卸载你自己的java。

正如@steven指出的，安装Java 8(这里有Ubuntu 16.04、18.04和20.04/20.10的链接https://computingforgeeks.com/how-to-install-java-8-on-ubuntu/)，然后用下面的命令将其设置为默认Java版本:

sudo update-alternatives --config java

Linux用户(我使用的是Debian发行版，Kali) 以下是我的解决方法。

如果您还没有jdk-8，您可以在oracle的网站上获得它

https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

我得到了jdk-8u191-linux-x64.tar.gz

步骤1 -安装Java 在一个合适的位置移动并打开它，像这样

$ mv jdk-8u191-linux-x64.tar.gz /suitablelocation/
$ tar -xzvf /suitablelocation/jdk-8u191-linux-x64.tar.gz

您应该得到一个解压缩的文件夹，如jdk1.8.0_191 您可以随后删除tarball以节省空间

步骤2 -设置默认java位置的替代方案

$ update-alternatives --install /usr/bin/java java /suitablelocation/jdk1.8.0_191/bin/java 1
$ update-alternatives --install /usr/bin/javac javac /suitablelocation/jdk1.8.0_191/bin/javac 1

步骤3 -选择您的默认选项

$ update-alternatives --set java /suitablelocation/jdk1.8.0_191/bin/java
$ update-alternatives --set javac /suitablelocation/jdk1.8.0_191/bin/javac

步骤4 -确认默认java版本

$ java -version

笔记

In the original article here: https://forums.kali.org/showthread.php?41-Installing-Java-on-Kali-Linux, the default plugin for mozilla was also set. I assume we don't really need the plugins as we're simply trying to develop for android. As in @spassvogel's answer, you should also place a @repositories.cfg file in your ~/.android directory as this is needed to update the tools repo lists Moving some things around may require root authority. Use sudo wisely. For sdkmanager usage, see official guide: https://developer.android.com/studio/command-line/sdkmanager

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
