Test subject:


mainFile.d

void main(){
        
}

otherFile.d
import std.stdio : writeln;
import std.file  : mkdir;

int main(){
        writeln("test ");
        return 0;
}


Error, main() method has been imported:
how to disallow main() method from being imported?
otherFile.d(5): Error: only one main, WinMain, or DllMain 
allowed. Previously found main at mainFile.d(3)

This has nothing to do with main being imported. It's because you 
*compiled* two main functions. If you absolutely want two main 
functions and can't see a better way to achieve whatever it is 
you're doing, then you can wrap them in version blocks:

module mainFile;

version(defaultMain) {
...
}

=========

module otherFile;

version otherMain() {
...
}
