Eclipse setup

Install and prepare Eclipse

  • Download and install Eclipse (Indigo or Juno is recommended);
  • Install Scala 2.10.x IDE plugin as described here. Make sure to get the right bundle / update site according with your Eclipse version;
  • Install IvyIDE plugin as described here. This will allow to automatically create classpath containers starting from ivy files;

Checkout Kafka source

Generate Eclipse project files

  • cd <kafka.project.dir>

  • Bootstrap gradle wrapper with: gradle

  • Generate the eclipse projects with: ./gradlew eclipse. This command will create eclipse projects for every project defined in Kafka. 

  • Note that the source folder structure may need to be fixed manually : see  Unable to render Jira issues macro, execution error.

Create the Eclipse workspace

  • Open Eclipse and create a new workspace;
  • Import the generated project (File -> Import -> General -> Existing Projects into Workspace)
    1. Navigate to the <kafka.project.dir>. Eclipse will find the projects generated by the previous command;
    2. Select the projects you want to import;

You should see the projects you have imported. For running unit tests and Kafka broker refer to the previous section.



You will need regenerate the projects and refresh eclipse every time there is a change in the projects dependencies. In other words, you need to run ./gradlew eclipse and refresh eclipse.

NOTE - update for Eclipse 3.7.x Oxygen and scala-ide 4.7.1RC3 ans Scala 2.12

After generating the projects with

gradle -PscalaVersion=2.12
./gradlew -PscalaVersion=2.12 eclipse --refresh-dependencies

In Eclipse you need some manual tweaking to get rid of the build errors :

  • remove the duplicate java src path entry from  core 
  • remove all 'test' library entries in the projects : core/streams/streams-scala

then, break the build cycle

  • remove the `test-utils` project dependency from streams
  • add the test-utils source folders `test-utils/src/main/java` and `test-utils/src/test/java` to the streams project 


Intellij Setup

  • Download and install IntelliJ;
  • Install the IntelliJ IDEA Scala Plugin (Menu Item File | Settings -> Plugins -> Browse Repositories -> Search for Scala);

  • cd <kafka.project.dir>
  • gradle
  • ./gradlew idea
