The instructions below works for Eclipse IDE.

• Download the HBC source files from https://github.com/twitter/hbc

• Create a Java project in your Eclipse IDE. Right-click on src folder and import the hbc-example source files from hbc-example/src/main/java
• Add the jar dependencies in the project build-path. These jar files could be found hbc-example/target/dependency
• Open a file say, SampleStreamExample. This is found within com.twitter.hbc.example package.
• Pass following for arg[0], arg[1], arg[2], arg[3] respectively and run the file. and, that is it. You should be able to see the message being retrieved from twitter.
  • Consumer key
  • Consumer secret
  • Access token
  • Access token secret
• You could experiment with other files in examples such as SitestreamExample, Twitter4jSampleStreamExample etc.
