MacOS: as3mxml.java.path in settings does not point to a valid executable.

[PippoApps]

No matter what I put in settings.json, really no matter what I tried everything, 5 different java versions, I still get:
as3mxml.java.path in settings does not point to a valid executable. It cannot be a directory, and Java JDK 11 or newer is required.

It lets me select SDK, but the extension does not work at all, since no java machine is found.
I tried /usr/bin/java, and other versions I have on the system, they all work in terminal, but no matter what the extension cannot find it...

I am lost, please a suggestion?

I also have temurin-25 installed. This path works on my Mac (though it detects the java executable automatically, and I don't normally need to use this setting).

"as3mxml.java.path": "/Library/Java/JavaVirtualMachines/temurin-25.jdk/Contents/Home/bin/java"

After changing the setting, try running the Developer: Reload Window command. Or, alternatively, Quit VScode (don't just close the current window, but fully Quit the app), and restart it.

yes that's really strange, I tried all sorts of macumbas, even ended the process

Checking the developer console I get several messages related to the extension though... might be something unrelated that interferes...

Unfortunately, this is a different issue. It would not cause the "as3mxml.java.path in settings does not point to a valid executable" error.

[PippoApps]

I get that message even if I delete the settings file altogether.

Could it be that there's a settings.json file somewhere in the VS Code settings outside the workspace?

[joshtynjala]

Yes, there are two places to configure settings. User settings and workplace settings.
