Implement Extern Constraint
An error or warning is triggered for extern constraints which are not implemented (explicit constraints trigger errors, while implicit ones trigger warnings).

Place the editor cursor on the constraint’s line and press Ctrl+1, select Implement extern constraint … from the list of quick fix proposals and press Enter.
The extern constraint implementation is inserted outside the class scope.

Tip
You can change the constraint block by editing the Constraint Code Templates
Note
The implementation stub contains a TODO reminder which shows up the Tasks View. See Track Tasks using TODO Markers.
