This is a graphical user interface for apt.
It is expected that the root folder of apt is next to the root folder of apt-gui in the file system.
home/
|--- apt/
| |--- classes/
| |--- lib/
| |--- build.xml
|--- apt-gui/
|--- build.gradle
You need to build apt first since the apt/classes folder is expected to be available for compilation of apt-gui. Then you can build apt-gui using the following commands:
cd apt-gui
./gradlew jar
Some other available build targets are: eclipse, javadoc
