Bootstrap not working with spring-boot?

I am attempting to install bootstrap for use in my spring boot project, which uses thymeleaf. I am getting this error with the template (index.html, shown below):

Malformed markup: Attribute "class" appears more than once in element

I assume this is because bootstrap isn't installed properly. Below I have an image of the files also. I am pretty sure all the dependencies are right.

INDEX HTML:

The exception will give the line # in the html where the error is occurring... in any case, the actual problem is here:

<div class="container" class="row">

Thymeleaf won't allow an element to have two attributes with the same name (Attribute "class" appears more than once in element). Just change it to:

<div class="container row">
