Welcome to the world of Egeria, where data governance meets innovation through an open metadata and governance framework. In this article, we will explore how to build and run Egeria from scratch, while also giving you some troubleshooting tips along the way.

What is Egeria?

Egeria provides a robust, Apache-2.0 licensed system that facilitates the exchange of metadata across various tools, engines, and platforms. This ensures not just the best value from data but also proper governance over it. Think of Egeria as a translator in a multilingual party, helping everyone understand each other and work together seamlessly.

Building and Running Egeria

Building Egeria requires a few simple steps. Below is a user-friendly guide to get you started:

1. Clone or Download the Repository:

   First, ensure you have the core Egeria repository. You can do this via Git:

   git clone https://github.com/odpi/egeria.git

   Alternatively, you can download the contents directly.

2. Install Java 17 SDK:

   Make sure you have the Java 17 SDK installed on your machine.

3. Build the Project:

   Navigate to the top-level directory of Egeria and execute the following command:

   ./gradlew clean build

   Once the process is complete, look for the message “Build Successful.”

4. Access the Build Directory:

   Next, navigate to the distribution directory here:

   cd .open-metadata-distribution/omag-server-platform/build

   This will bring you to the area where you can see essential directories.

5. Explore Subdirectories:

   Use the following command to view the subdirectories:

   ls

   The two most relevant directories here are:

   • distributions: Contains the zipped distribution file for Egeria.
   • unpacked: Holds an unzipped copy of the distribution, useful for running Egeria directly on your build machine.

6. Run Egeria:

   To run Egeria, change your directory to:

   cd unpacked/egeria*

   Here, you’ll find another README.md file that contains additional information.

   cat README.md

Troubleshooting

If you encounter issues while following the steps mentioned above, here are a few troubleshooting tips:

• If the build does not complete successfully, ensure that you’ve correctly installed Java 17 SDK and that your environment variables are properly configured.
• Check for network issues that may have interrupted the downloading or cloning process.
• If you cannot find certain directories, ensure that you are executing the commands in the correct paths.
