Error creating class GhidraAnalyzer when creating extension points for ghidra.app.services.Analyzer

[vanhauser-thc]

I compiled GhidrAI for Ghdira 11.0.2 (note that I had to remove line 106 in src/main/java/ghidrai/ui/GhidraiDialog.java because of illegal characters).

I installed the plugin and enabled it, however when starting ghidra on a target I get this error:

Ghidra Version: 11.0.2
Java Home: /usr/lib/jvm/java-17-openjdk-amd64
JVM Version: Private Build 17.0.10
OS: Linux 6.5.0-26-generic amd64

Is that an incompatibility with Ghidra 11?

Seems that you didn't set your DASHSCOPE_API_KEY env. The Alibaba Dashscope SDK always load its API key from environment.
Try to add the export DASHSCOPE_API_KEY=YOUR_DASHSCOPE_API_KEY=${your Dashscope key} to your ~/.bashrc (or other configuration file, upon your shell).

As for the illegal characters in the GhidraiDialog.java comment, maybe your platform did not support Chinese character, you can help remove this comment or translate it to English and submit a PR :)
