graal-sdk-mock

This project can be considered as a subproject of Panama Native Interface, but can be used independently as well.

How to Use

For compiling:

compileOnly 'io.vproxy:graal-sdk-mock-nativeimage:1.2.2'

and in your module-info.java

requires org.graalvm.nativeimage;

For running:

runtimeOnly 'io.vproxy:graal-sdk-mock-runtime:1.2.2'

You must not use ImageInfo, use ImageInfoDelegate instead.

Why Mock?

1. Smaller

Only provides necessary types and members for Panama Native Interface.

2. Non-NativeImage Friendly

It's quite common to use the same codebase for JVM and Graal native-image, so it's very likely that you will need to check whether the program is running in JVM or native-image.

Graal SDK provides ImageInfo for you to check.

However the ImageInfo class is placed inside module org.graalvm.nativeimage, and some types in the module MUST NOT be included when building a native image.

So it would be impossible to build a native-image using a shadow (fat) jar.

With the help of graal-sdk-mock-runtime, you are able to run shadow (fat) jar in JVM, and build the native-image with exactly the same shadow (fat) jar.
