README

Apache Kafka

See our web site for details on the project.

You need to have gradle installed.

First bootstrap and download the wrapper

cd kafka_source_dir
gradle

Now everything else will work

Building a jar and running it

./gradlew jar  

Follow instuctions in http://kafka.apache.org/documentation.html#quickstart

Building source jar

./gradlew srcJar

Building javadocs and scaladocs

./gradlew javadoc
./gradlew javadocJar # builds a jar from the javadocs
./gradlew scaladoc
./gradlew scaladocJar # builds a jar from the scaladocs
./gradlew docsJar # builds both javadoc and scaladoc jar

Running unit tests

./gradlew test

Forcing re-running unit tests w/o code change

./gradlew cleanTest test

Running a particular unit test

./gradlew -Dtest.single=RequestResponseSerializationTest core:test

Running a particular test method within a unit test

./gradlew core:test --tests kafka.api.test.ProducerFailureHandlingTest.testCannotSendToInternalTopic
./gradlew clients:test --tests org.apache.kafka.clients.producer.MetadataTest.testMetadataUpdateWaitTime

Running a particular unit test with log4j output

change the log4j setting in either clients/src/test/resources/log4j.properties or core/src/test/resources/log4j.properties
./gradlew -i -Dtest.single=RequestResponseSerializationTest core:test

Building a binary release gzipped tar ball

./gradlew clean
./gradlew releaseTarGz  
The above command will fail if you haven't set up the signing key. To bypass signing the artifact, you can run
./gradlew releaseTarGz -x signArchives

The release file can be found inside ./core/build/distributions/.

Cleaning the build

./gradlew clean

Running a task on a particular version of Scala (either 2.9.1, 2.9.2, 2.10.5 or 2.11.6)

(If building a jar with a version other than 2.10, need to set SCALA_BINARY_VERSION variable or change it in bin/kafka-run-class.sh to run quick start.)

./gradlew -PscalaVersion=2.9.1 jar
./gradlew -PscalaVersion=2.9.1 test
./gradlew -PscalaVersion=2.9.1 releaseTarGz

Running a task for a specific project

This is for 'core', 'contrib:hadoop-consumer', 'contrib:hadoop-producer', 'examples' and 'clients'

./gradlew core:jar
./gradlew core:test

Listing all gradle tasks

./gradlew tasks

Building IDE project

./gradlew eclipse
./gradlew idea

Building the jar for all scala versions and for all projects

./gradlew jarAll

Running unit tests for all scala versions and for all projects

./gradlew testAll

Building a binary release gzipped tar ball for all scala versions

./gradlew releaseTarGzAll

Publishing the jar for all version of Scala and for all projects to maven

./gradlew uploadArchivesAll

Please note for this to work you should create/update ~/.gradle/gradle.properties and assign the following variables

mavenUrl=
mavenUsername=
mavenPassword=
signing.keyId=
signing.password=
signing.secretKeyRingFile=

Publishing the jars without signing to a local repository

./gradlew -Dorg.gradle.project.skipSigning=true -Dorg.gradle.project.mavenUrl=file://path/to/repo uploadArchivesAll

Building the test jar

./gradlew testJar

Determining how transitive dependencies are added

./gradlew core:dependencies --configuration runtime

Running checkstyle on the java code

./gradlew checkstyleMain checkstyleTest

Running in Vagrant

See vagrant/README.md.
