Build and run the samples

Requirements

Mac OS X and iOS

• Download this version of GraalVM: https://download2.gluonhq.com/substrate/graalvm/graalvm-svm-darwin-20.1.0-ea+28.zip and unpack it like you would any other JDK. (e.g. in /opt)

• Configure the runtime environment. Set GRAALVM_HOME environment variable to the GraalVM installation directory.

  For example:

  export GRAALVM_HOME=/opt/graalvm-svm-darwin-20.1.0-ea+28
  

• Set JAVA_HOME to point to the GraalVM installation directory

  For example:

  export JAVA_HOME=$GRAALVM_HOME
  

Linux and Android

• Download this version of GraalVM: https://download2.gluonhq.com/substrate/graalvm/graalvm-svm-linux-20.1.0-ea+28.zip and unpack it like you would any other JDK. (e.g. in /opt)

• Configure the runtime environment. Set GRAALVM_HOME environment variable to the GraalVM installation directory.

  For example:

  export GRAALVM_HOME=/opt/graalvm-svm-linux-20.1.0-ea+28
  

• Set JAVA_HOME to point to the GraalVM installation directory

  For example:

  export JAVA_HOME=$GRAALVM_HOME
  

Windows

• Download the latest development version of GraalVM: https://github.com/graalvm/graalvm-ce-dev-builds/releases by choosing graalvm-ce-java11-windows-amd64-20.2.0-dev.zip from the list of assets and unzip it to a preferred location on your system.

• Make sure you have installed Visual Studio 2019 with the following components:

  • Choose the English Language Pack
  • C++/CLI support for v142 build tools (14.25 or later)
  • MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.25 or later)
  • Windows Universal CRT SDK
  • Windows 10 SDK (10.0.19041.0 or later)

• Run the maven commands mentioned below in a x64 Native Tools Command Prompt for VS 2019. This command prompt can be accessed from the start menu.

• Configure the runtime environment. Set GRAALVM_HOME environment variable to the GraalVM installation directory.

  For example:

  set GRAALVM_HOME=C:\tools\graalvm-ce-java11-20.2.0-dev
  

  Install native-image by running:

  %GRAALVM_HOME%\bin\gu install native-image
  

• Set JAVA_HOME to point to the GraalVM installation directory

  For example:

  set JAVA_HOME=%GRAALVM_HOME%
  

Build using Maven

HelloWorld, HelloFX, HelloFXML and HelloGluon samples

The following goals apply to Linux, Mac OS X and Windows.

To build the native image:

mvn clean client:build

To run the native image:

mvn client:run

or simply run the native executable found in target/client.

Build and run the samples on iOS

Additional requirements

• iOS can be built only on Mac OS X

• Install Homebrew, if you haven't already. Please refer to https://brew.sh/ for more information.

• Install libusbmuxd

Using brew:

brew install --HEAD libusbmuxd

• Install libimobiledevice

Using brew:

brew install --HEAD libimobiledevice

Build using Maven

HelloWorld, HelloFX, HelloFXML and HelloGluon samples

• Set the target to ios (for iOS devices) in the pom.xml:

<artifactId>client-maven-plugin</artifactId>
<configuration>
    <target>ios</target>
    <mainClass>${mainClassName}</mainClass>
</configuration>

• Build the native image:

mvn clean client:build

• Run the app on the connected iOS device:

mvn client:run

• Package and create an IPA file to submit to TestFlight or to the App Store:

mvn client:package

Note: Since all java bytecode is translated to native code, the compilation step can take a long time, and it requires a fair amount of memory.

Note: In order to deploy apps to an iOS device, you need a valid iOS provisioning profile, as explained in the documentation.

Build and run the samples on Android

Additional requirements

• Android can be built only on Linux OS

The client plugin will download the Android SDK and install the required packages. Alternatively, you can define a custom location to the Android SDK by setting the ANDROID_SDK environment variable, making sure that you have installed all the packages from the following list:

• platforms;android-27
• platform-tools
• build-tools;27.0.3
• ndk-bundle
• extras;android;m2repository
• extras;google;m2repository

Build using Maven

HelloWorld, HelloFX, HelloFXML and HelloGluon samples

• Set the target to android (for android devices) in pom.xml:

<artifactId>client-maven-plugin</artifactId>
<configuration>
    <target>android</target>
    <mainClass>${mainClassName}</mainClass>
</configuration>

• Build the native image:

mvn clean client:build

• Package and create an APK file:

mvn client:package

• Install the APK file on a connected Android device:

mvn client:install

• Run the installed app on the connected Android device:

mvn client:run

Note: Since all java bytecode is translated to native code, the compilation step can take a long time, and it requires a fair amount of memory.
