ghidra: update CI Workflow to reflect recent Ghidrathon changes

[colton-gabertan]

Summary

The latest release candidate for Ghidrathon now includes an installation script. This now outdates the method used in the Ghidra backend's CI workflow. Please update the workflow to use the new installer.

Thank you for opening, great idea! With the latest changes to Ghidrathon we can download the pre-built extension and remove the Gradle build steps from our CI workflow.

Hello, can I please take this up? I also noticed version upgrade is needed for jep and ghidrathon, should I bump up version in this change?

Thank you for reaching out @psahithireddy - I've assigned this issue to you. The goal here is to update capa's existing Ghidra test workflow to leverage the simplified Ghidrathon v4 installation steps outlined in its README. Specifically, we want to substitute building Ghidrathon with downloading the latest pre-built release from GitHub.

As you already mentioned, let's also update the versions:

• Ghidra -> 11.0.1
• Ghidrathon -> 4.0.0
• Jep -> 4.2.0 (this is installed as part of the simplified Ghidrathon v4 steps)

Reach out here if you have any questions! 🚀

Hi @mike-hunhoff, I have few questions

1. In the installation steps for ghidrathon, I believe you missed mentioning cd /util to run requirements.txt and ghidrathon_configure.py.
2. Also, do I need to add the installation of requirements.txt into CI workflow as it only contains jep, which is already in CI workflow.
   Thanks :)

The Ghidrathon-v4.0.0.zip file contains three files:

requirements.txt and ghidrathon_configure.py can be used as described Ghidrathon's installation steps. The embedded Ghidrathon-v4.0.0.zip should be extracted directly to <absolute_path_to_ghidra_install_dir>\Ghidra\Extensions. From there, we can run the CI tests.

So the first step here is to update the CI workflow to download and extract the Ghidrathon-v4.0.0.zip file instead of building it from source.

[psahithireddy]

Understood. My apologies for the bad PRs, I now found a way to trigger ci workflow to test it without PR, in my local. Should I update the CHANGELOG too?

Thanks a lot for your help!
