The first lesson of using
#Ghidra's generated VSCode project is that I'm a VSCode n00b :P Lessons so far:
1) You'll need the Extension Pack for Java (from MS, not Oracle's crap!)
2) Ghidra launch configurations are available under the "bug with play button" sidebar icon
+1) Directory/workspace names are not necessarily valid Java package names, but Ghidra generates the code and the fs structure anyway
Now I'm trying to figure out why the sample code is not actually loaded to Ghidra when debugging...
