Building From Source
Pull latest from repo git pull origin master and use Maven install (or package) to build mvn clean install.
Testing
Hazelcast has 3 testing profiles:
- Default: Type
mvn test to run quick/integration tests (those can be run in parallel without using network).
- Slow Tests: Type
mvn test -P slow-test to run tests that are either slow or cannot be run in parallel.
- All Tests: Type
mvn test -P all-tests to run all tests serially using network.
Checkstyle and SpotBugs
Hazelcast uses static code analysis tools to check if a Pull Request is ready for merge.
Run the following commands locally to check if your contribution is Checkstyle and SpotBugs compatible.
mvn clean validate -P checkstyle
mvn clean compile -P spotbugs
