ev3dev.menu

Motivation

EV3 Brick is the third generation of LEGO Mindstorms with the enough CPU & Memory to run a complete Debian distro and a JVM.

When you run a program in Java, you open a terminal and type:

java -jar ./yourJar.jar

But when you are in a competition like FLL, you need some utility to load programs easily and this project try to tackle this problem.

Goals

• Run a Jar from another Jar
• Develop a UI to load files in a default folder from EV3
• Download files from github repos and run
• Package in the same program (JRI, Program, Dependencies) JEP 343

Initial works

Currently, it is possible to execute a Jar from another Jar. Build the project:

mvn clean package

and copy the jar from target folder to docs and execute it from there. In the folder docs, exist a jar created for the example demo.jar

java -jar menu-0.1.0-SNAPSHOT.jar
Running another jar
