 CAUTION: To create a native image, the compiler toolchain for your platform needs to be installed. See https://www.infoq.com/articles/java-native-cli-graalvm-picocli/[Build Great Native CLI Apps in Java with Graalvm and Picocli] for details.

 [TIP]
 ====
 Native images on Windows have the https://github.com/oracle/graal/issues/1762[problem] that the native image does not include the required dependency `msvcr100.dll` (for Java 8) or `VCRUNTIME140.dll` (with GraalVM 19.3 or later for Java 11). On Windows machines where this dependency is not in the `PATH`, the native image fails to start, and shows an error dialog "System Error: The program can't start because VCRUNTIME140.dll is missing from your computer".
