Experimenting with JShell

You can experiment with the client from JShell. This requires Java 9 or more.

git clone https://github.com/rabbitmq/rabbitmq-java-client.git
cd rabbitmq-java-client
./mvnw test-compile jshell:run
...
import com.rabbitmq.client.*
ConnectionFactory cf = new ConnectionFactory()
Connection c = cf.newConnection()
...
c.close()
/exit

Building from Source

Getting the Project and its Dependencies

git clone git@github.com:rabbitmq/rabbitmq-java-client.git
cd rabbitmq-java-client
make deps

Building the JAR File

./mvnw clean package -Dmaven.test.skip

Launching Tests with the Broker Running in a Docker Container

Run the broker:

docker run -it --rm --name rabbitmq -p 5672:5672 rabbitmq

Launch "essential" tests (takes about 10 minutes):

./mvnw verify \
    -Drabbitmqctl.bin=DOCKER:rabbitmq \
    -Dit.test=ClientTestSuite,FunctionalTestSuite,ServerTestSuite

Launch a single test:

./mvnw verify \
    -Drabbitmqctl.bin=DOCKER:rabbitmq \
    -Dit.test=DeadLetterExchange

Launching Tests with a Local Broker

The tests can run against a local broker as well. The rabbitmqctl.bin system property must point to the rabbitmqctl program:

./mvnw verify \
       -Dtest-broker.A.nodename=rabbit@$(hostname) \
       -Drabbitmqctl.bin=/path/to/rabbitmqctl \
       -Dit.test=ClientTestSuite,FunctionalTestSuite,ServerTestSuite

To launch a single test:

./mvnw verify \
       -Dtest-broker.A.nodename=rabbit@$(hostname) \
       -Drabbitmqctl.bin=/path/to/rabbitmqctl \
       -Dit.test=DeadLetterExchange
