Question

In my project I have something like final boolean Debug.USE_DEBUG_MODE and I’m then always forgetting to switch it back to false.
I wonder if I can put something similar to the #warning C++ directive so I don’t forget to change the code back.

You can use the //TODO Change this later Task Tag in eclipse and configure Eclipse to display a compile-time warning for all TODOs.

public static void main(String[] args) {
    //TODO Change this line before final build.
    String mode = "DEV"
}

You can see all such Task Tags collectively, in one place by doing Window > Show View > Markers.

Note that there are others too, like FIXME, XXX. By default the priority of a TODO tag is NORMAL and that of FIXME is a HIGH.
