If I try to run this app (mvn spring-boot:run), I got:

Error starting Tomcat context. Exception: org.springframework.beans.factory.UnsatisfiedDependencyException. Message: Error creating bean with name 'graphQLServletRegistrationBean' defined in class path resource [graphql/kickstart/spring/web/boot/GraphQLWebAutoConfiguration.class]: Unsatisfied dependency expressed through method 'graphQLServletRegistrationBean' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'graphQLHttpServlet' defined in class path resource [graphql/kickstart/spring/web/boot/GraphQLWebAutoConfiguration.class]: Unsatisfied dependency expressed through method 'graphQLHttpServlet' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'graphQLServletConfiguration' defined in class path resource [graphql/kickstart/spring/web/boot/GraphQLWebAutoConfiguration.class]: Unsatisfied dependency expressed through method 'graphQLServletConfiguration' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'invocationInputFactory' defined in class path resource [graphql/kickstart/spring/web/boot/GraphQLWebAutoConfiguration.class]: Unsatisfied dependency expressed through method 'invocationInputFactory' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'graphQLSchemaProvider' defined in class path resource [graphql/kickstart/spring/web/boot/GraphQLWebAutoConfiguration.class]: Unsatisfied dependency expressed through method 'graphQLSchemaProvider' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'graphQLSchema' defined in class path resource [graphql/kickstart/tools/boot/GraphQLJavaToolsAutoConfiguration.class]: Unsatisfied dependency expressed through method 'graphQLSchema' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'schemaParser' defined in class path resource [graphql/kickstart/tools/boot/GraphQLJavaToolsAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [graphql.kickstart.tools.SchemaParser]: Factory method 'schemaParser' threw exception; nested exception is java.lang.IllegalStateException: No graphql schema files found on classpath with location pattern '**/*.graphqls'.  Please add a graphql schema to the classpath or add a SchemaParser bean to your application context.

But why? I have all needed dependency for graphql, but still there is some unsatisfied dependency. What is it?

These errors are very confusing, but your application can't run because it don't find any schemas.

No graphql schema files found on classpath with location pattern '**/*.graphqls'.  Please add a graphql schema to the classpath or add a SchemaParser bean to your application context.

The graphql schemas in a java environment mostly ends with s or you can specify your own schema parser (Docu).

Hint: The most gql exceptions have a large stackstrace and all starts with a ServletException but is caused by something else.
