# Development environment
I develop this on Windows 7, in Java 8 in Eclipse.

Steps to install everything:
* download a Java 11 JDK and put it in tools/jdk
* download Eclipse and put in in the tools/eclipse directory (for example)
* install the eclipse SVN plugin, using this update site: https://dl.bintray.com/subclipse/releases/subclipse/4.2.x/

Steps to prepare the Eclipse environment:
* open a command line to the checked out project, enter the 'ttnhabbridge' directory
* type 'env.bat' to initialise the tool paths etc
* enter directory gradle
* type 'gradlew eclipse' and watch dependencies being downloaded from the internet
* start Eclipse, using the 'workspace' directory as workspace
* import sub-projects (ttnhabbridge, cayenne) into the workspace

Steps to update source code from github:
* in the top-level 'ttnhabbridge' directory, enter 'git pull'

Steps to create the executable package:
* enter the 'gradle' directory, then type './gradlew assemble' (or just 'gradlew assemble' on Windows)
* the .tar (for Linux) or .zip (for Windows) file can be found under ttnhabbridge/build/distributions

# Deployment
Steps to deploy the application:
* unzip the .zip or .tar file
* cd into the application directory
