JAVA IMAGE TOOLS FULL
Run native-image -help to see the full list. There many options you can pass to the native-image builder to configure the image build process.
JAVA IMAGE TOOLS HOW TO
The command to build a native executable from a Java module is: native-image -module įor more information about how to produce a native executable from a modular Java application, see Building a HelloWorld Java Module into a Native Executable. You can also convert a modularized Java application into a native executable. App someArgument.įollow this guide to build a native executable from a JAR file. For example, java -jar App.jar someArgument becomes native-image -jar App.jar and. The default behavior of native-image is aligned with the java command which means you can pass the -jar, -cp, -m options to build with Native Image as you would normally do with java. To build a native executable from a JAR file in the current working directory, use the following command: native-image -jar jarfile You can time it to see the resources used: time -f 'Elapsed Time: %e s Max RSS: %M KB'. It will create a native executable, helloWorld, in the current working directory.
JAVA IMAGE TOOLS CODE
Save this code into file named HelloWorld.java:.To build a native executable from a Java class file in the current working directory, use the following command: native-image class įor example, build a native executable for a HelloWorld application.
