默认命令行参数值存在编译错误

Question

As I try to take a command line argument of type uint64, when I am setting default value to a valid unsigned 64 bit number, I am getting following compilation error.

Compilation Error: Expression type mismatch, the expected type is uint64 less... It highlights the number 5000 here indicating that's not an acceptable value.

Code:

var golferInstance uint64 

flag.Uint64Var(&golferInstance, "inst", 5000, "Golfer Instance ID, this should be Globaly Unique ")
flag.Parse()

I don't see anything wrong with above declaration, then why is the compilation error ??

What am I missing here? (i believe must be something silly that i fail to make out) Any help is appreciated.

Thanks

The Inspection type in the go-lang-idea-plugin has some issues regarding certain type Mismatch detection.
See issue 348 (which is supposed to be solved in latest version of that plugin)

You can un-select that inspector.

In the interface it's called 'Highlight mismatched types', I believe this is the one.
The message from inspection is: 'Expression type mismatch, expected type is ...'

It also seems it has problems in detecting that '1 * time.Second' in the construct 'time.Sleep(1 * time.Second)' is a proper 'Duration' type and it tries to fix it like this 'time.Sleep((time.Duration)(1 * time.Second))'.

Falling back to command line, and/or making sure all components are up-to-date (golang IntelliJ plugin, Go itself), can help.
