[FIXED] Failed to install android-sdk: "java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema"

Issue

When installing the android sdk tools the following error is emitted:

java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema

Why is this happening and how can it be fixed?

Debug output:

$ 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.

Solution

I had a similar problem this morning (trying to build for Android using Unity3D). I ended up uninstalling JDK9 and installing Java SE Development Kit 8u144. Hope this helps.

1. brew cask uninstall java # uninstall java9
2. brew tap homebrew/cask-versions
3. brew cask install java8 # install java8
4. touch ~/.android/repositories.cfg # without this file, error will occur on next step
5. brew install --cask android-sdk
