In client apps, dashboard URL returns 404 without spring-boot-starter-web

[donaldoakes]

Without this dependency, the Dashboard (and in fact all top-level Index.jsx assets) return 404 to the browser (bypassing MDW's NotFoundServlet).

compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: springBootVersion

For the time being I've updated the build.gradle template to include the 'spring-boot-starter-web' dependency. However, I'm leaving this issue open in hopes we can understand the root cause and revert this hard dependency on starter-web.
