installer's Introduction

Installer

A Bash script to install everything related with EV3Dev-lang-java

Test result on master:

Motivation

EV3Dev is a fantastic Complete Linux environment to build software for robots with Java. But as any technology, the installation require some configuration to run in the right way.

This project tries to save time in this process.

The installer will install the following libraries by default:

OpenJDK 11 JRI for EV3, OpenJDK 11 JRE for the rest of the bricks

It is possible to install the following libraries if your project requires them.

OpenCV
RXTX (Serial port library used on RPLIDAR4J)

Note Play with the help in order to discover the different options.

Getting Started

Starting point:

The starting point to use this installer, is a Brick running with EV3Dev and updated:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo reboot

Running the installer

cd /home/robot
wget -N https://raw.githubusercontent.com/ev3dev-lang-java/installer/master/installer.sh
chmod +x installer.sh
sudo ./installer.sh help
sudo ./installer.sh

installer's Issues

Installer does not find jri-11-ev3

I did the recommended

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo reboot

and then downloaded and starte the installer.sh to install java.

robot@ev3dev:~$ sudo ./installer.sh java

##############################
# EV3Dev-lang-java Installer #
##############################

Platform detected: ev3

No java detected
Installed Java version: '', installing anyway.
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package jri-11-ev3

And not really a suprise:

robot@ev3dev:~$ sudo apt-get install jri-11-ev3
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package jri-11-ev3

So it looks that jri-11-ev3 is not a valid apt package name.

Installer is not working

Using template project, I am trying to install OpenJDK in one Brick, but installer is not working:

From template project, I call the gradle task to install, installer:

> Task :getInstaller
mkdir /home/robot/installer
wget -N https://raw.githubusercontent.com/ev3dev-lang-java/installer/master/installer.sh -P /home/robot/installer

Handle Java updates & multiple versions

Oracle wasn't releasing minor Java updates for EV3, so we were stuck with one version. This has changed - openjdk-ev3 can be rebuilt at any time.

Not sure if this is the right place to report this. There seems to be an inconsistency in the version of lejos-commons used between the different repositories. The script in this repository installs 0.7.2 on the brick, but e.g., the gradle wrapper provided in projects such as temple_project_gradle and examples generate jar files with 0.7.3 in their classpath (in the MANIFEST.MF). So when just following the examples on the web page, the code will not run on the brick, but instead give a ClassNotFoundException for the lejos classes.

P2P installer

Quoting from a readme:

It is nice to configure one brick but maybe you could discover that the installer could move the JDK one manual process to another brick and hte installer it is possible to replicate to another remote brick. Play with the help to discover the way.

Well, it might be possible to connect to a different brick via Bluetooth PAN. You could then compress the installed JDK, transfer it over SCP/SSH to the second brick and then unpack it there. IDK about how to fully automate it.

Platform UNKNOWN in Lego device

I've a lego Brick device with ev3dev (kernel 4.4.87-22 last one I guess).
When I run installer.sh and download platform.sh, platform appears as UNKNOWN because in the if sentence it search lego-v3-battery but in my device the file is named as legov3-battery.

Regards.

Merge Installer refactoring

https://github.com/ev3dev-lang-java/installer/pull/5/files

Add support for platform detection on Jessie

Remove Java-based BatteryMonitor

Convert to Debian package(s)

A small shell script putting this all together (maybe even without using apt-get update) should remain, but non-trivial stuff should be put into its own debian package.

Add support for OpenJDK 10 for Raspberry Pi

https://wiki.debian.org/Java/

installer wipes OpenJRE 11 and installs nothing

Did the manual install of the OpenJRE 11 on a fresh Linux installation (2018-11-13 Snapshot) according to the tutorial http://ev3dev-lang-java.github.io/docs/support/getting_started/brick.html:

wget obtained the file jri-ev3.tar.gz.
The command: sudo tar -zxvf jri-ev3.tar.gz -C /opt extracted the content to: /opt/jri
Then I renamed that: sudo mv /opt/jri/ /opt/jri-11
Then I did sudo update-alternatives --install /usr/bin/java java /opt/jri-11/bin/java 11
And finally java -Xshare:dump
Then JRE 11 was installed.

However, after installing the installer.sh and running sudo ./installer.sh java the following happened:

I have also tried to run the ping test which is also not working. Yet, when I run it on the normal command prompt everything is working fine.

function installJavaForEV3(){
    if [ -e "/home/robot/ejdk-8-fcs-b132-linux-arm-sflt-03_mar_2014.tar.gz" ]; then
        tar -zxvf "/home/robot/ejdk-8-fcs-b132-linux-arm-sflt-03_mar_2014.tar.gz" -C /opt

    else
        echo "Sorry, the installer didn´t detect ejdk-8-fcs-b132-linux-arm-sflt-03_mar_2014.tar.gz"
        echo "on /home/robot"
        echo "try to copy the file again to the EV3 Brick."
        echo
        exit 1
    fi
}

but it is necessary to upgrade this function to download in an automated way latest JRI, Java Runtime Image compiled:
