Spring boot application: doesn't compile application.properties?

Question

I have a spring boot application that I got here: https://github.com/christophstrobl/spring-data-solr-showcase/tree/4b3bbf945b182855003d5ba63a60990972a9de72

It compiles and works great with: mvn spring-boot:run

However, when I click "run as Spring Boot application" in the Spring Tools Suite, I get an inability to find message ${solr.host}configured in the application.properties file.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.data.solr.showcase.product.ProductServiceImpl.setProductRepository(org.springframework.data.solr.showcase.product.ProductRepository); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productRepository': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'solr.host' in string value "${solr.host}"

My application.properties file is as follows:

# SPRING MVC
spring.view.suffix=.jsp
spring.view.prefix=/WEB-INF/views/

# SOLR
solr.host=http://192.168.56.11:8983/solr

The corresponding class is as follows (the only place where the $ solr.host variable is used). In addition, if I directly access the IP address of the SOLR server (as in the commented-out code), the application starts up normally.
