Test Compile on Beaglebone Green

[adamjvr]

Just tested compilation of the application on the Beaglebone Green. Here is what happened:

adam@beaglebone:~/vivaplanet-java/src/vivaplanetjava0$ javac DeviceReport.java  Sensors.java  VivaPlanetJava0.java

VivaPlanetJava0.java:24: error: package com.google.gson does not exist

It appears it can't find google's gson java library. Investigating this further. Beaglebone Green Linux Version:

Download those files from Google and put them on the BB. On Sun, Sep 20, 2015 at 5:28 PM Adam Vadala-Roth notifications@github.com wrote:

I got the files, now its a matter of determining the proper location to install them too to the java compiler knows where the references are.

There are two paths in the Java you need to mod on The BB as well. I'll send you the text file with the sensor data on it tonight On Sun, Sep 20, 2015 at 7:11 PM Adam Vadala-Roth notifications@github.com wrote:

I added the following to my bash profile, and refreshed it before attempting another compile:

#########################################################################
#           GOOGLE gson-2.3.1
#########################################################################
export PATH=$PATH:/opt/google.gson/gson-2.3.1-javadoc.jar
export CLASSPATH=$CLASSPATH:/opt/google.gson/gson-2.3.1-javadoc.jar
export PATH=$PATH:/opt/google.gson/gson-2.3.1-javadoc.jar
#########################################################################
#            GOOGLE gson-2.3.1
#########################################################################

First compile after adding the jar to the PATH resulted in:

adam@beaglebone:~/vivaplanet-java/src/vivaplanetjava0$ javac DeviceReport.java  Sensors.java  VivaPlanetJava0.java
error: error reading /opt/google.gson/gson-2.3.1-javadoc.jar; /opt/google.gson/gson-2.3.1-javadoc.jar (Permission denied)
1 error

So I tried:

sudo chmod 777 /opt/google.gson -R

Compiled again and got:

adam@beaglebone:~/vivaplanet-java/src/vivaplanetjava0$ javac DeviceReport.java  Sensors.java  VivaPlanetJava0.java
