Failed to run sdkmanager –list with Java 9

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

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?

Answer

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.

  1. Open sdkmanager in your favorite editor.
  2. 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"'
    
  3. 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'
    
  4. Save the file and quit the editor.
  5. Run the command again.

Here is the result:

$ sdkmanager --list

Hola! It works!

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.
