See our web site for details on the project.
You need to have gradle installed.
cd kafka_source_dir
gradle
Now everything else will work
./gradlew jar
Follow instuctions in http://kafka.apache.org/documentation.html#quickstart
./gradlew srcJar
./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
./gradlew test
./gradlew cleanTest test
./gradlew -Dtest.single=RequestResponseSerializationTest core:test
./gradlew core:test --tests kafka.api.test.ProducerFailureHandlingTest.testCannotSendToInternalTopic
./gradlew clients:test --tests org.apache.kafka.clients.producer.MetadataTest.testMetadataUpdateWaitTime
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
./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/.
./gradlew clean
(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=2.11.7 jar
./gradlew -PscalaVersion=2.11.7 test
./gradlew -PscalaVersion=2.11.7 releaseTarGz
This is for 'core', 'contrib:hadoop-consumer', 'contrib:hadoop-producer', 'examples' and 'clients' ./gradlew core:jar ./gradlew core:test
./gradlew tasks
./gradlew eclipse
./gradlew idea
./gradlew jarAll
./gradlew testAll
./gradlew releaseTarGzAll
./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=
./gradlew -Dorg.gradle.project.skipSigning=true -Dorg.gradle.project.mavenUrl=file://path/to/repo uploadArchivesAll
./gradlew testJar
./gradlew core:dependencies --configuration runtime
./gradlew checkstyleMain checkstyleTest
