Repository Overview (README excerpt)
Crawler viewSummary A lightweight open framework for building fast and efficient cloud-native Java microservices: • Open Liberty is fast to start up with low memory footprint and live reload for quick iteration. • Simple to add and remove features from the latest versions of MicroProfile and Java EE. • Zero migration lets you focus on what's important, not the APIs changing under you. Getting Started Launch a sample app using Maven git clone https://github.com/OpenLiberty/sample-getting-started.git cd sample-getting-started mvn clean package liberty:run Open browser to http://localhost:9080/ and explore the demo application. See this guide to learn how it works. Downloads • Maven Central • Open Liberty website • Docker Hub Usage Docker • This guide demonstrates development using Docker containers. Maven • This guide demonstrates development using the Liberty Maven Plugin. Command Line • This reference demonstrates the basic server operation commands. Open Liberty Docs • Open Liberty Guides • Reference docs including features, config and API's Contributing Our CONTRIBUTING document contains details for submitting pull requests. **FYI:** The project recently renamed branch to . More info here: https://github.com/OpenLiberty/open-liberty/wiki/Master-rename-to-Release Running a Build • Clone the repository to your system. git clone git@github.com:OpenLiberty/open-liberty.git • Run a gradle build. Prerequisite - Environment variable must point to a Java 17 or Java 21 SDK. If setting to Java 17, you will also need to set to a Java 21 SDK. cd open-liberty/dev ./gradlew cnf:initialize ./gradlew assemble Troubleshooting - If shows out of memory error, you can increase the memory in file. Stop the gradle daemon after you change the memory setting by using . If it does not help the problem, try cleaning up your maven repository cache (using ) and gradle cache (using ). • Run the unit or FAT tests. for unit tests to run a FAT project **NOTE:** runs the and tasks • Perform a local release **NOTE:** This task releases all projects to the local releaseRepo.
