Description
JApplication is a task for assembling native launchers of Java applications for a number of target platforms. Currently supports native launchers for Mac and Windows operating systems and also a "java launcher" - a single jar file that can be run via "java -jar file.jar".
OS Strategies
- Java: builds a single runnable jar file out of a collection of jar files.
- Mac: builds a XYZ.app bundle that includes all jar dependencies.
- Windows: Performs a Java build and creates an NSIS launcher for the runnable jar. Both ".exe" and ".jar" files are required to be in the same directory for the launcher to work.
OS Requirements
- Mac launcher can be built on Mac only, as it requires a JavaApplicationStab file.
- Windows launcher can be built on Windows only.
- Java launcher can be assembled on any platform and has no prerequisites.
