Recieving java.lang.IllegalArgumentException: target cannot be null

[EliasMPJunior]

Hello,

This project sounds awesome! But I've tried to start using it and wasn't able to.

The code bellow is what I have done:

Class<?> classSpec = new Mirror().reflectClass(classPath); // classPath - My own class

new Mirror().on(classSpec).invoke().setterFor(objectColumnName).withValue(columnValue);

// objectColumnName and columnValue are String and are OK.

I also tried the the string classPath instead of Class classSpec, but got the same result.

Trace is here:

Hello Elias,

Can you add the stacktrace you're getting? From what I see some value
passed is null (Mirror checks all the values passed) but I cannot see which
one.

Best regards,
