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.

Tests

$ ./gradlew test

Building

$ ./gradlew clean assemble

BUILD SUCCESSFUL in 2s
6 actionable tasks: 6 executed

$ 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:

1. Create the build directory and populate with uber-jars in build/libs.
2. 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:
