Venice Workspace Setup#

We recommend using a Unix-based environment for development, such as Linux or macOS. If you're on Windows, we recommend using WSL2.

Fork the Venice Repository#

Fork the Venice repo at https://github.com/linkedin/venice.

Setting up the repository locally#

git clone git@github.com:${githubUsername}/venice.git
cd venice
git remote add upstream git@github.com:linkedin/venice.git
git fetch upstream

Setting up Java#

We use Java 17 for development. You can download it here.

Make sure to set the JAVA_HOME environment variable to the location of your JDK installation. How to do this will be dependent on your OS.

Setting up the IDE#

We recommend using IntelliJ IDEA for development to take advantage of the debugger, and provide instructions for it. However, any IDE of your choice should work.

To set up IntelliJ, run: 

./gradlew idea

Disable wildcard imports#

  1. In IntelliJ, click the gear icon in the top right and select settings
  2. Go to Editor -> Code Style -> Java and select Imports from the tabs
  3. Next to Scheme, select the gear icon and hit duplicate
  4. Only check Use single class import
  5. Set Class count to use import with * to 1000
  6. Set Names count to use static import with * to 1000

Setting up your system#

Set the maximum number of open files limit#

There are many resources on the web for updating the limits of maximum number of open files for each operating system. We recommend setting a soft limit of at least 64000 and a hard limit of at least 524288. Feel free to experiment with various values and find ones that work for you.

Build the project#

./gradlew clean assemble

Run the test suite#

./gradlew check --continue

Gradle Cheatsheet#

# Build project classes and artifacts
./gradlew assemble

# Run all checks (spotbugs, code coverage, tests etc)
./gradlew check --continue

# Run only enabled checks that may fail the build
./gradlew spotbugs

# Run all checks, including ones that are in review/incubating stage, and do not fail the build
./gradlew spotbugs -Pspotallbugs -Pspotbugs.ignoreFailures

# Run jacoco code coverage check, which will also generate jacoco report
./gradlew jacocoTestCoverageVerification

# Run jacoco code coverage check along with jacoco report and diff coverage check
./gradlew jacocoTestCoverageVerification diffCoverage --continue

# Run enabled checks only for main code and in da-vinci-client subproject
./gradlew :clients:da-vinci-client:spotbugsMain

 # Run jacoco code coverage check for a specific module along with jacoco report
./gradlew :clients:da-vinci-client:jacocoTestCoverageVerification

# Run jacoco code coverage check for a specific module along with jacoco report and diff coverage check
./gradlew :clients:da-vinci-client:jacocoTestCoverageVerification diffCoverage

# Run a specific test in any module
./gradlew :sub-module:testType --tests "fully.qualified.name.of.the.test"
