Debugging with IntelliJ IDEA

Install Harness using the instructions for building from source. This will pull the source code into a directory for access by IDEA.

Debugging Harness Server

Harness Server can be debugged with the Harness CLI or by sending event and/or queries from something like the Java SDK all from with the Server setup.

  1. Launch IntelliJ and pick File -> New -> Project from existing sources. Navigate to harness/rest-server, pick import using SBT and finish. You will now be able to run the server, trigger CLI, and the simple examples in the Java SDK project.
  2. Setup CLI debugging:

    • To debug the CLI bring up the "edit debug configurations" pick Bash applications and set the working directory to your equivalent of /Users/pat/harness/rest-server/bin This will then be set for all Bash commands

    • Create a debug config for bash the looks like:

    • harness start This is the only CLI that does not trigger from Bash. Set it up like this:

    • harness delete <resource-id> and the other CLI can be set to trigger using our bash defaults and setting the specific options needed. For example: this will perform the equivalent of harness delete <resource-id>. as you can see I have created add and delete of 2 different engines for testing.

    • Note: This is quite setup correctly yet but should work. Input for the Java SDK example. We have scripts that will compile the example and launch it. The scripts take parameters to control what event json is sent to the server among other things. To input event json, fir launch the server as shown above then run the following Bash run config (notice the working directory is different than other Bash CLI commands.

Debugging the Java SDK and Examples

  1. Lunch IntelliJ and pick File -> New -> Project from existing sources. Then navigate to harness/java-sdk, pick import using Maven, and check the "search for projects recursively". When you hit next you will see:

import Java SDK and examples

If you don't see 2 projects something is wrong, there should be the SDK itself and and examples project.

  1. Finish importing. You will be able to launch the examples in harness/java-sdk/example using typical methods but since the SDK communicates with the Harness Server make sure it is running.
