Installing Java

Check if java is already installed

  • Click on the Start Button and type 'Command Prompt' and hit enter

  • In the window type 'java -version'

  • If your output looks like the one in the screenshot below, then probably java is not installed on your computer. Java not Installed

  • It could be a possibility that java is installed but Environment Variable is not set.

  • To check that go to 'C:\Program Files' and see if you see a folder named Java. If there is no folder like that then we can be sure that Java is not installed on your computer.

  • In case you find the Java folder there, then skip to Set Environment Variable Section

Install Java

Check for OS Architecture

  • Before we start downloading Java, we need to check the what is your OS Architecture in order to install the correct version of Java
  • There are two ways to do it:
    • Through File Explorer
      • Click on Start -> File Explorer, if that option is not available, open any folder
      • Right Click on 'This PC' and choose Properties as shown in the screenshot below Computer Properties
      • Once done look for the 'System Type' on a window similar to the one below OS Architecture
      • If your system type is '64 bit operating system' then your system has 64 bit architecture
    • Through Command Prompt
      • Click on the start button and type ‘command prompt’, click on the application to open. Once your command prompt is open type either of the following commands in order to get the architecture of the system
        • wmic os get osarchitecture
          OS Arc Command 1
        • echo %PROCESSOR_ARCHITECTURE%
          OS Arc Command 2

Download and Install Java

  • Once you know the architecture information of your system, go here
  • Accept the License and choose the version of JDK that suits the version of your operating system, e.g. if your system is 32 bit choose 'Windows x86', if it is 64 bit choose 'Windows x64'
  • In my case it happens to be 64 bit architecture, thus we are downloading ‘Windows x64’ version. Java Download
  • Once downloaded, double click on the downloaded file, based on your security setting you might get a dialog to confirm opening of the .exe file, just click Run. Now you should see a dialog like this Java Download Setup
  • Click Next. On the next screen make note of the installation directory, in my case it is installing in C:\Program Files\Java\jdk1.8.0_151\ which you can see at the bottom left side of the screen. This is required to set the environment variable at a later stage
    JDK installation folder
  • Click Next. The installation will begin, while installing it may ask you to change the installation directory for JRE, just let it set to default and click Next.
    JRE Installation Folder
  • Click Finish on the next screen, once the installation is completed.
Check Installation
  • Go to the command prompt and type 'java -version' Java not Installed
  • If you see something like above then Environment Variable is not set.
Set Environment Variable
  • Open File explorer -> Right click on 'This PC' -> Click on Properties, Once you do that you will get a window like this
    Advanced System Setting
  • Click on Advanced System Settings. You should get a Window like this System Properties
  • Click on Environment Variables, which should give you a window like this Environment Variables
  • Click on Path and Click Edit. In Variable value at the end type the path of the Java installation directory, for which you made the note earlier which in my case is C:\Program Files\Java\jdk1.8.0_151\ and append bin at the end like this.
    Edit User Variable
  • Click OK and open a new Command Prompt window (as explained earlier) and type java -version. Now you should see something like this.
    Java Installed
Congratulations you have successfully installed java, now let's move on to installing Gradle

Installing Gradle

Check if gradle is installed

  • Open Command Prompt and type gradle --version. If your output looks like this Gradle not Installed
  • Then the gradle application is not installed.

Download and Install Gradle

  • In order to install gradle go here and scroll down for the latest version and click on complete as shown here Gradle Download
  • Save the file and unzip it at your preferred location, in my case it is unzipped under Program Files in order to be consistent as application are usually installed under Program Files.
  • Once unzipped navigate to the bin folder of gradle which in my case is C:\Program Files\gradle-4.3.1-all\gradle-4.3.1\bin as the files were extracted in Program Files as described earlier. Copy the path of the bin folder by clicking the Address Bar in the File Explorer as shown in the screenshot below. Gradle folder path
  • Once the path is copied, follow the steps described in the Java Installation section to navigate to the Environment Variable windows, as shown below Env screen
  • Choose Path and click Edit, you would see a window like this Gradle pre env screen
  • Click on New and Paste the path that you copied of Gradle bin, Now your window should look like this Gradle set env
  • Click OK to save and dismiss this dialog box. Click OK again to dismiss the Environment Variable dialog box and Click OK to dismiss System Settings dialog. Now open a new window of Command Prompt and type gradle --version and you should see something like this Gradle installed
Congratulations now you have gradle installed on your computer. Let’s move to install Postgresql

Installing Postgresql and Postgis

Install Postgresql

  • To install Postgresql, go here. You should see a screen something like
    Postgres download
  • Choose the latest version and Select the operating system, based on the architecture of the system you need to choose the Operating system. In my case the system architecture is 64 bit, below screenshot displays the version and operating system selected

  • Navigate to the Environment variable window as described in the Java installation section, and when you are on Edit environment variable screen, click on New and paste the address of the Postgresql bin directory that you copied a little while ago and click OK
    Postgres set env
  • Now open a new window of Command Prompt and type psql -U postgres as by default Postgresql creates a postgres account, upon entering the above command it will prompt you to enter password for postgres user which you have set while installing the Postgresql. Type the same password in and you should see something like below. Screenshot below shows a Postgresql shell. Type \q to quit.
    Postgres installed
Congratulations now you have installed Postgres and Postgis.

Installing Git

Check if Git is already installed

  • Lets first check if Git is installed on your machine or not. Open a new Command prompt window and type git --version, if you see something like below then we could say that git is not installed on your computer. It could be that Git is installed but Environment Variable is not set. You could check that by going to the C:\Program Files if you would see a folder named Git then you just need to set Environment Variable path. If that is the case please feel free to the section where we are setting Environment Variable
    Git not installed

Download Git

  • Go here and scroll down to Downloads section and click the latest version of the application which has .exe extension, which in my case is Git-2.15.0-32-bit.exe
    Git Download

Install Git

  • Double click on the file once it is downloaded and click Run.
  • Click Next on the license page
  • Leave the installation directory to default on Select Destination Location box and click Next

  • Click Next on Configuring the line ending conversions box
  • Click Next on Configuring the terminal emulator to use with Git Bash box
  • Click Install on Configuring extra options, this will start installing Git on your machine
  • Once the installation is complete, click Finish
Note: We still need to set environment variable in order for git command to work from Command Prompt

Set Environment Variable

  • Navigate to the bin directory of Git which in my case is C:\Program Files\Git\bin. Click on the address bar of the file explorer and copy the path.
    Set git env
  • Navigate to the Environment variable window as described in the Java installation section, and when you are on Edit environment variable screen, click on New and paste the address of the Git bin directory path that you copied a little while ago and click OK
    Git env set
  • To test the installation again, open a new Command Prompt and type git --version and you should see something like this.
    Git installed
Congratulations, you now have git installed on your machine.
Now that we have all the dependencies installed, let’s start working with Tombolo

Clone Tombolo Digital Connector Repository

  • To clone Tombolo Digital Connector repository, click here then click on Clone or Download and copy the path Git tombolo clone
  • Open a new Command Prompt and make sure that you present working directory is your home directory. You can check that by looking the path in the Command Prompt window before >, in my case is looks like this Check present working dir
  • If yours also follows the same pattern as C:\Users\<user-name> then you are good to go. If not then change it by typing cd C:\Users\<user-name>. Now that we are in our home directory, we can type following commands to clone TomboloDigitalConnector repo.
cd Desktop
mkdir Tombolo
cd Tombolo
git clone https://github.com/FutureCitiesCatapult/TomboloDigitalConnector.git
  • Now wait for it to download, when it is downloaded you would see something like below. Git cloning tombolo
  • Now type cd TomboloDigitalConnector.
  • We have rename 2 project files gradle.properties.example and apikeys.properties.example. To do that just type the following commands in Command Prompt
rename gradle.properties.example gradle.properties
rename apikeys.properties.example apikeys.properties

Setup Databases

Main Database

  • Type the following commands
psql -U postgres
Enter the password for the account and hit enter (You have set this password while installing postgres)
CREATE USER tombolo WITH PASSWORD ‘tombolo’;
CREATE DATABASE tombolo WITH ENCODING=UTF8;

Pg create role Pg create database

  • Make tombolo a superuser
ALTER USER tombolo WITH SUPERUSER;

Pg alter role

  • Type \q to quit
  • We now need to create postgis extension
psql -d tombolo -U tombolo
Enter the password as tombolo and now Type the following commands
CREATE EXTENSION postgis;
SET NAMES ‘UTF8’;

Pg create extension

  • Type \q to quit
  • Now run the sql script to setup your database
psql -d tombolo -U tombolo < src\main\resources\sql\create_database.sql
Enter the password as ‘tombolo’

Tombolo script output

Test Database

  • The steps for setting up the test database is same as setting up the main database. Thus follow the steps starting from Main Database section and replace tombolo with tombolo_test everywhere even for the passwords. Below are just the screenshots for the steps: Tombolo Test database Tombolo Test database 2
Congratulations now your both the databases are setup.

Build and Run the project

Build

  • Now you are all set to build the project TomboloDigitalConnector. To build the project in Command Prompt type the following
gradle clean build
  • Running the aforementioned command should start downloading the packages required to run DigitalConnector, once the packages is downloaded it will start building the DigitalConnector and start running the tests, on a machine with 8gb of ram it should not take more than 15 minutes to run the tests, once the downloads are done.
  • Below are couple screenshots of the start of the process and end of the process. Gradle build Gradle build 2
Congratulations you have successfully built the Digital Connector. Now let’s try to run an example.
