Template project with Gradle

Why

Test a new technology is always a bit tedious and it requires an amount of time. So, this project try to reduce the curve of learning of any new user with EV3Dev-lang-java.

Prerequisites

The Prerequisites to use this project are:

Your MINDSTORMS Brick needs to have installed latest Debian Stretch version. https://www.ev3dev.org/docs/getting-started/
To increase the EV3 CPU Speed, read the following article: https://lechnology.com/2018/06/overclocking-lego-mindstorms-ev3-part-2/
Your MINDSTORMS Brick needs to be connected to the same LAN than your laptop. http://www.ev3dev.org/docs/getting-started/#step-5-set-up-a-network-connection

Note: Update the EV3Dev kernel https://www.ev3dev.org/docs/tutorials/upgrading-ev3dev/

sudo apt-get update
sudo apt-get install linux-image-ev3dev-ev3

Once you have all steps done, continue with the next section.

Getting Started

This repository stores a template project about EV3Dev-lang-java. Once you download in your computer the project, open your favourite Java IDE ( Eclipse or IntelliJ) to import this Gradle project. The project includes latest dependencies and an example ready to be deployed on your Robot using the core library from EV3Dev-lang-java.

The project includes some tasks to reduce the time to deploy on your robot.

Review the IP of your Brick and update the file ./config.gradle:

remotes {
    ev3dev {
        host = '192.168.1.180'
        user = 'robot'
        password = 'maker'
    }
}

EV3Dev-lang-java

The tasks associated to deploy on your Robot are:

testConnection (Test the connection with your Brick)
deploy (The project deliver a FatJar to your Brick)
remoteRun (Execute a Jar deployed on your Brick)
deployAndRun (Deploy & Execute from your Computer the program that you configured on the file: MANIFEST.MF)
ev3devInfo (Get technical information about your EV3 Brick)
removePreviousJar (Remove current jar remotely)
remoteBrickRun (If your program is going to use some EV3 Actuator like LCD, Buttons, use this task to execute the program)
remoteRun (Execute your jar remotely)
remoteRunClassVerbose (Execute your jar and show JVM info)
remoteProfilingRun (Execute your jar configured for Profiling activities)
deployAndBrickRun (Deploy & Execute your program with Brickrun)
deployAndProfilingRun (Deploy & Execute your jar configured for Profiling activities)
pkillJava (Kill Java processes in your Brick)

You can use the Java IDE to launch the task or execute them from the terminal

./gradlew deployAndBrickRun
