How to Build and Run Apache Hop: A Step-by-Step Guide

Jun 8, 2023 | Programming

The Apache Hop Orchestration Platform is designed to facilitate data and metadata orchestration seamlessly. This guide will walk you through the process of building and running Apache Hop, ensuring you have a stable user experience while contributing to its growth.

Prerequisites: What You Need

  • OpenJDK: Ensure you have the Java 17 compiler installed. Check OpenJDK for more details.
  • Maven: Install version 3.6.3 or higher from Maven.

Step 1: Verify Your Setup

Before diving into the build process, verify that Maven is configured correctly by running this command:

mvn -version

Step 2: Cloning Apache Hop

Start by cloning the Apache Hop repository to your local machine. Use this command:

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

Step 3: Building Apache Hop

Navigate to the cloned repository. There are two methods to build the code:

  • Using Maven: Run the following commands:
  • cd hop
    mvn clean install
  • Using Maven Wrapper: If Maven is not accessible, the wrapper handles it for you:
  • cd hop
    .mvnw clean install

Step 4: Running Apache Hop

After a successful build, proceed with launching the Hop User Interface:

cd assemblies/client/target
unzip hop-client-*.zip
cd hop

Finally, start the application:

  • On Windows: run hop-gui.bat
  • On Mac/Linux: run hop-gui.sh

Understanding the Build Process: An Analogy

Think of building Apache Hop like preparing a complex dish in a fancy kitchen. The OpenJDK is your set of high-quality ingredients, ensuring everything cooks perfectly. Maven acts as your trusted recipe book, laying out the steps and ensuring you adhere to them correctly.

When you clone the repository, it’s akin to gathering all your ingredients into one place. Building with the right command is just like following the recipe steps precisely, ensuring that at the end, you serve a delightful dish (in this case, your working application).

Troubleshooting Tips

  • If you encounter errors while building, check that you are using the correct version of Java and Maven. Make sure to update to the latest patch versions.
  • If the GUI fails to launch, verify that all required dependencies are properly installed.
  • For any issues, log bugs or request features in the GitHub repository or ask questions in the mailing lists or Mattermost.
