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 2.8.0, 2.8.2, 2.9.1, 2.9.2 or 2.10.1) (If building a jar with a version other than 2.8.0, the scala version variable in bin/kafka-run-class.sh needs to be changed 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', 'perf', '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=
