问题:
I downloaded and installed:
- JDK (
jdk-9.0.1_osx-x64_bin.dmg) from Oracle here - Android SDK (
sdk-tools-darwin-3859397.zip) from Google here.
After configuring the PATH variable, I tried running sdkmanager, which replaced the android command for managing SDK components. However, it failed as shown here:
$ sdkmanager --list Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156) at com.android.repository.api.SchemaModule.<init>(SchemaModule.java:75) at com.android.sdklib.repository.AndroidSdkHandler.<clinit>(AndroidSdkHandler.java:81) at com.android.sdklib.tool.SdkManagerCli.main(SdkManagerCli.java:117) at com.android.sdklib.tool.SdkManagerCli.main(SdkManagerCli.java:93) Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlSchema at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:185) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:496) ... 5 more
Here is the Java version:
$ 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)
Does anyone know how to fix it without going back to Java 8?

With the help of this answer, I successfully solved the problem.
We are going to apply a fix in sdkmanager. It is a shell script. It is located at $android_sdk/tools/bin, where $android_sdk is where you unzipped the Android SDK.
- Open
sdkmanager in your favorite editor. Locate the line which sets the DEFAULT_JVM_OPTSvariable. In my copy, it is at line 31:
DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME"'
Append the following options to the variable: -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee. Please pay attention to the quotes. In my copy, the line becomes:
DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME" -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'
- Save the file and quit the editor.
- Run the command again.
Here is the result:
$ sdkmanager --list Installed packages: Path | Version | Description | Location ------- | ------- | ------- | ------- tools | 26.0.1 | Android SDK Tools 26.0.1 | tools/ Available Packages: Path | Version | Description ------- | ------- | ------- add-ons;addon-g..._apis-google-15 | 3 | Google APIs add-ons;addon-g..._apis-google-16 | 4 | Google APIs add-ons;addon-g..._apis-google-17 | 4 | Google APIs add-ons;addon-g..._apis-google-18 | 4 | Google APIs add-ons;addon-g..._apis-google-19 | 20 | Google APIs add-ons;addon-g..._apis-google-21 | 1 | Google APIs add-ons;addon-g..._apis-google-22 | 1 | Google APIs add-ons;addon-g..._apis-google-23 | 1 | Google APIs add-ons;addon-g..._apis-google-24 | 1 | Google APIs ...
Hola! It works!
-- Edit: 2017-11-07 --
Please note that you may need to apply the fix above again after running sdkmanager --update, since the sdkmanager shell script may be overridden if the tools package is updated.

You can set sdkmanager options with SDKMANAGER_OPTS.
Example:
export SDKMANAGER_OPTS="--add-modules java.se.ee" sdkmanager --list

The Android Tools are still incompatible with JDK 9 or 10. You need to install JDK 8 or, if you need multiple Java versions make sure that the system-wide Java home points to a JDK 8.
