You will need:

OpenRefine source code
Java JDK (Get OpenJDK from here.)
Apache Maven (OPTIONAL)
A Unix/Linux shell environment OR the Windows command line

From the top level directory in the OpenRefine application you can build, test and run OpenRefine using the ./refine shell script (if you are working in a *nix shell), or using the refine.bat script from the Windows command line. Note that the refine.bat on Windows only supports a subset of the functionality, supported by the refine shell script. The example commands below are using the ./refine shell script, and you will need to use refine.bat if you are working from the Windows command line.

Set up JDK

You must install JDK and set the JAVA_HOME environment variable (please ensure it points to the JDK, and not the JRE).

import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem';

On Windows 10, click the Start Menu button, type env, and look at the search results. Click Edit the system environment variables. (If you are using an earlier version of Windows, use the “Search” or “Search programs and files” box in the Start Menu.)

Click Environment Variables… at the bottom of the Advanced window.
In the Environment Variables window that appears, click New… and create a variable with the key JAVA_HOME. You can set the variable for only your user account, as in the screenshot below, or set it as a system variable - it will work either way.

Set the Value to the folder where you installed JDK, in the format D:\Programs\OpenJDK. You can locate this folder with the Browse directory... button.

First, find where Java is on your computer with this command:

which java

Check the environment variable JAVA_HOME with:

$JAVA_HOME/bin/java --version

To set the environment variable for the current Java version of your MacOS:

export JAVA_HOME="$(/usr/libexec/java_home)"

Or, for Java 13.x:

export JAVA_HOME="$(/usr/libexec/java_home -v 13)"

With the terminal

Enter the following:

sudo apt install default-jre

This probably won’t install the latest JDK package available on the Java website, but it is faster and more straightforward. (At the time of writing, it installs OpenJDK 11.0.7.)

Manually

First, extract the JDK package to the new directory usr/lib/jvm:

sudo mkdir -p /usr/lib/jvm
sudo tar -x -C /usr/lib/jvm -f /tmp/openjdk-14.0.1_linux-x64_bin.tar.gz

Then, navigate to this folder and confirm the final path (in this case, usr/lib/jvm/jdk-14.0.1). Open a terminal and type

sudo gedit /etc/profile

In the text window that opens, insert the following lines at the end of the profile file, using the path above:

JAVA_HOME=/usr/lib/jvm/jdk-14.0.1
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export PATH

Save and close the file. When you are back in the terminal, type

source /etc/environment

Exit the terminal and restart your system. You can then check that JAVA_HOME is set properly by opening another terminal and typing

echo $JAVA_HOME

It should show the path you set above.

Maven (Optional)

OpenRefine's build script will download Maven for you and use it, if not found already locally installed.

If you will be using your Maven installation instead of OpenRefine's build script download installation, then set the MVN_HOME environment variable. You may need to reboot your machine after setting these environment variables. If you receive a message Could not find the main class: com.google.refine.Refine. Program will exit. it is likely JAVA_HOME is not set correctly.

Ensure that you set your MAVEN_HOME environment variable, for example:

MAVEN_HOME=E:\Downloads\apache-maven-3.5.4-bin\apache-maven-3.5.4\

NOTE: You can use Maven commands directly, but running some goals in isolation might fail (try adding the compile test-compile goals in your invocation if that is the case).

Building

To see what functions are supported by OpenRefine's build system, type

./refine -h

To build the OpenRefine application from source type:

./refine clean
./refine build

Testing

Since OpenRefine is composed of two parts, a server and a in-browser UI, the testing system reflects that:

on the server side, it's powered by TestNG and the unit tests are written in Java;
on the client side, we use Cypress and the tests are written in Javascript

To run all tests, use:

./refine test

this option is not available when using refine.bat

If you want to run only the server side portion of the tests, use:

./refine server_test

If you are running the UI tests for the first time, you must go through the installation process.
If you want to run only the client side portion of the tests, use:

./refine ui_test chrome

Running

To run OpenRefine from the command line (assuming you have been able to build from the source code successfully)

./refine

By default, OpenRefine will use refine.ini for configuration. You can copy it and rename it to refine-dev.ini, which will be used for configuration instead. refine-dev.ini won't be tracked by Git, so feel free to put your custom configurations into it.

Building Distributions (Kits)

The Refine build system uses Apache Ant to automate the creation of the installation packages for the different operating systems. The packages are currently optimized to run on Mac OS X which is the only platform capable of creating the packages for all three OS that we support.

To build the distributions type

./refine dist <version>

where 'version' is the release version.

Building, Testing and Running OpenRefine from Eclipse

OpenRefine' source comes with Maven configuration files which are recognized by Eclipse if the Eclipse Maven plugin (m2e) is installed.

At the command line, go to a directory not under your Eclipse workspace directory and check out the source:

git clone https://github.com/OpenRefine/OpenRefine.git

In Eclipse, invoke the Import... command and select Existing Maven Projects.

Choose the root directory of your clone of the repository. You get to choose which modules of the project will be imported. You can safely leave out the packaging module which is only used to generate the Linux, Windows and MacOS distributions.

To run and debug OpenRefine from Eclipse, you will need to add an execution configuration on the server sub-project. Right click on the server subproject, click Run as... and Run configurations... and create a new Maven Build run configuration. Rename the run configuration OpenRefine. Enter the root directory of the project as Base directory and use exec:java as a Maven goal.

This will add a run configuration that you can then use to run OpenRefine from Eclipse.

Testing in Eclipse

You can run the server tests directly from Eclipse. To do that you need to have the TestNG launcher plugin installed, as well as the TestNG M2E plugin (for integration with Maven). If you don't have it, you can get it by installing new software from this update URL http://dl.bintray.com/testng-team/testng-eclipse-release/

Once the TestNG launching plugin is installed in your Eclipse, right click on the source folder "main/tests/server/src", select Run As -> TestNG Test. This should open a new tab with the TestNG launcher running the OpenRefine tests.

Test coverage in Eclipse

It is possible to analyze test coverage in Eclipse with the EclEmma Java Code Coverage plugin. It will add a Coverage as… menu similar to the Run as… and Debug as… menus which will then display the covered and missed lines in the source editor.

Debug with Eclipse

Here's an example of putting configuration in Eclipse for debugging, like putting values for the Google Data extension. Other type of configurations that can be set are memory, Wikidata login information and more.

Building, Testing and Running OpenRefine from IntelliJ idea

At the command line, go to a directory you want to save the OpenRefine project and execute the following command to clone the repository:

git clone https://github.com/OpenRefine/OpenRefine.git

Then, open the IntelliJ idea and go to file -> open and select the location of the cloned repository.

It will prompt you to add as a maven project as the source code contains a pom.xml file in it. Allow auto-import so that it can add it as a maven project. If it doesn't prompt something like this then you can go on the right side of the IDE and click on maven then, click on reimport all the maven projects that will add all the dependencies and jar files required for the project.

After this, you will be able to properly build, test, and run the OpenRefine project from the terminal. But if you will go to any of the test folders and open some file it will show you some import errors because the project isn't yet set up at the module level.

For removing those errors, and enjoying the features of the IDE like ctrl + click, etc you need to set up the project at the module level too. Open the different modules like extensions/wikidata, main as a project in the IDE. Then, right-click on the project folder and open the module settings.

In the module settings, add the source folder and test source folders of that module.

Then, do the same thing for the main OpenRefine project and now you are good to go.
