'kapt not working with maven and dagger in mixed kotlin/java project
Kapt doesnt work with maven, if we dont use kapt and just use the maven compiler for java it generates dagger code perfectly fine, but the problem is that java compiles after kotlin compiles and kotlin gives and error because it can't use dagger components before they are created, so the solution would be to use kapt. this is the plugin configuration
