Developer Notes

AppleCommander has switched to using Gradle for build and build dependencies.

There is still a bunch of ANT related build information around. They no longer apply and "should" get cleaned up over time.

Structure

The project is structured as a Gradle multi-project. Independent components have been broken out and each of the SWT targets are independent.

Path	Note
`lib/ac-api`	The AppleCommander APIs. These are released via Maven and resused in several projects.
`lib/ac-swt-common`	The SWT GUI application. Since SWT targets specific environments with native libraries, the actual applications are in the `app` directories.
`app/cli-ac`	The `ac` CLI utility.
`app/cli-acx`	The `acx` CLI utility.
`app/gui-swt-<os>-<arch>`	The indepent SWT GUI applications; one project per combination.

Requirements

With the introduction of the Apple Silicon, AppleCommander switched over to the (relatively new) SWT libraries. With that switch, the SWT libraries now require Java 11.

Older notes..

Just keeping these for the short-term...

$ tools/retrolambda.sh build/libs/AppleCommander-ac-<version>.jar
Converting...
Retrolambda 2.5.6
Repackaging to build/libs/AppleCommander-ac-<version>-java5.jar

This will:

Create the build directory and populate with uber-jars in build/libs.
Create a Java 5 variant of the ac tool in AppleCommander-ac-<version>-java5.jar. (Replace <version> with version.)

To run the command-line version of AppleCommander, use the following:

All platforms: java -jar build/libs/AppleCommander-ac-VERSION.jar
Java 5: java -jar build/libs/AppleCommander-ac-VERSION-java5.jar

To launch the GUI version of AppleCommander, use the following:

Linux: java -jar build/libs/AppleCommander-linux64-gtk-VERSION.jar
Windows: java -jar build/libs/AppleCommander-win64-VERSION.jar
Mac OS X: java -XstartOnFirstThread -jar build/libs/AppleCommander-macosx-VERSION.jar

Raspberry Pi Notes

Available versions found are: 3.8 and 4.6. 4.6 failed with a JNI issue.

Retrieve libraries:

$ sudo apt install libswt-gtk-3-java libswt-gtk-3-jni

Combine into one JAR (-j drops the directories from *.so files in the zip file):

$ cp /usr/lib/java/swt-gtk-3.8.2.jar org.eclipse.swt.gtk.linux.arm-3.8.2.jar
$ zip -j org.eclipse.swt.gtk.linux.arm-3.8.2.jar /usr/lib/jni/libswt-*3836*.so

Preserve JAR file in rpi-lib! If the file name is incorrect, the build process will show the expected filename in the error message...

Error for 4.6:
