title: Error processing condition on org.springframework.boot.autoconfigure.context.PropertyPlaceholderAutoConfiguration
body: <p>After adding 2 dependencies shown below to my application everything works fine my session data is written to my local redis server, but when i try to specify different address of redis server i got an error. I assume that error is connected with some dependencies problem, but i dont know how to tackle this issue.</p>
  
  <pre><code>compile "org.springframework.boot:spring-boot-starter-data-redis-reactive:${springVersion}"
  compile "org.springframework.session:spring-session-data-redis:${springVersion}"
  </code></pre>
  
  <p>Error during startup</p>
