Trying to load 2025 AprilTag JSON from file

Technical Java
1

I can get the “new AprilTagFieldLayout(string)” constructor to work.

Just trying to load the new JSON file from a file to get ahead of the game.

If I do this…

public static AprilTagFieldLayout aprilTagLayout = new AprilTagFieldLayout("mytagfile.json");

In the editor, not while building, the line shows an error and the error is
“Unhandled exception type IOExceptionJava(16777384)”

So the editor itself is telling me this is an IOException.
It’s not telling me this when trying to build or run the code.
I understand getting this when I run the code and the library can’t read the file but to have the editor throw this exception is new to me.

The editor is telling you the constructor could throw that exception, and you need to use a try-catch block to have a fallback.
