anja

Added JVM desktop binding support.

New desktop/JVM packaging

anja bind now supports building desktop JVM artifacts in two ways:

-target=android -desktop: also builds a desktop JAR in addition to the Android AAR.
-target=jvm: builds only the desktop JAR (no AAR output).

Basic usage

Build only desktop JAR:

anja bind -target=jvm ./your/pkg

Set JAR output path:

anja bind -target=jvm -o mylib.jar ./your/pkg

Build Android AAR + desktop JAR together:

anja bind -target=android -desktop -o mylib.aar ./your/pkg

Desktop target selection

Use -desktoptargets to control native platforms included in the desktop JAR.

Default:

-desktoptargets=host

Example:

anja bind -target=jvm \
  -desktoptargets host,linux/amd64,darwin/arm64,windows/amd64 \
  -jniinclude /path/to/jni-headers \
  -desktopo mylib-desktop.jar \
  ./your/pkg

Custom JNI headers

Use -jniinclude when the JNI headers for desktop builds should come from a specific directory instead of the default JAVA_HOME lookup.

Directory layout:

/path/to/jni-headers/
├── jni.h
├── darwin
│   └── jni_md.h
├── linux
│   └── jni_md.h
└── win32
    └── jni_md.h

Example:

anja bind -target=jvm \
  -jniinclude /path/to/jni-headers \
  ./your/pkg

Lookup order for each desktop target:

First check <jniinclude>/jni.h and <jniinclude>/<os>/jni_md.h.
os maps to linux, darwin, or win32.
If the configured directory does not contain matching JNI headers, fall back to the existing JAVA_HOME / javac detection.

Supported target syntax:

host
linux or linux/<arch>
darwin or darwin/<arch>
windows or windows/<arch>

Supported desktop arches by platform:

Linux: 386, amd64, arm, arm64
macOS: amd64, arm64
Windows: 386, amd64, arm64

Notes

Desktop builds require a full JDK (JNI headers), usually via JAVA_HOME.
Use -jniinclude to point desktop builds at a custom JNI headers directory. anja checks <root>/<os>/ first and falls back to the existing JAVA_HOME detection when the platform headers are not present.
Cross-platform desktop builds require matching C cross-compilers/toolchains installed.
