- Java 11+
In spite of the requirements of using JDK 11+ to build this project, client artifacts (and its dependencies) must be compatible with a Java 8 runtime. All other components are built and ran using JDK11+.
The clientJavaVersion project property determines the version used to build the client (defaults to 8).
Checkout the source code:
git clone https://github.com/pravega/pravega.git
cd pravega
Build the pravega distribution:
./gradlew distribution
Install pravega jar files into the local maven repository. This is handy for running the pravega-samples locally against a custom version of pravega.
./gradlew install
Running unit tests:
./gradlew test
Pravega uses Project Lombok so you should ensure you have your IDE setup with the required plugins. Using IntelliJ is recommended.
To import the source into IntelliJ:
- Import the project directory into IntelliJ IDE. It will automatically detect the gradle project and import things correctly.
- Enable
Annotation Processingby going toBuild, Execution, Deployment->Compiler>Annotation Processorsand checking 'Enable annotation processing'. - Install the
Lombok Plugin. This can be found inPreferences->Plugins. Restart your IDE. - Pravega should now compile properly.
For eclipse, you can generate eclipse project files by running ./gradlew eclipse.
Note: Some unit tests will create (and delete) a significant amount of files. For improved performance on Windows machines, be sure to add the appropriate 'Microsoft Defender' exclusion.
The latest pravega releases can be found on the Github Release project page.
