Native Image Build Overview

The syntax of the native-image command is:

  • native-image [options] <mainclass> [imagename] [options] to build a native binary from the main class in the current working directory. The classpath may optionally be provided with the -cp <classpath> option where <classpath> is a colon-separated (on Windows, semicolon-separated) list of paths to directories and JAR files.
  • native-image [options] -jar jarfile [imagename] [options] to build a native binary from a JAR file.
  • native-image [options] -m <module>/<mainClass> [imagename] [options] to build a native binary from a Java module.

The options passed to native-image are evaluated from left to right. For an overview of options that can be passed to native-image, see here.
