Setting up your IDE

Apache Pulsar is using lombok so you have to ensure your IDE setup with required plugins.

Intellij

To configure annotation processing in IntelliJ:

  1. Open Annotation Processors Settings dialog box by going to Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors.

  2. Select the following buttons:

    1. "Enable annotation processing"
    2. "Obtain processors from project classpath"
    3. "Store generated sources relative to: Module content root"

  3. Set the generated source directories to be equal to the Maven directories:

    1. Set "Production sources directory:" to "target/generated-sources/annotations".
    2. Set "Test sources directory:" to "target/generated-test-sources/test-annotations".

  4. Click "OK".

  5. Install the lombok plugin in intellij.

Eclipse

Follow the instructions here to configure your Eclipse setup.
