Spring data couchbase / Spring boot: continue execution on connection attempt failed - spring

Question

I'm trying to find a way to continue startup sequence of a Spring Boot App, using spring-data-couchbase, which would be unable to connect to the cluster set-up in the configuration.
Unfortunately, this has proven to be unsuccessful and the execution stops with this exception:
2017-01-16 13:14:09.513 ERROR 2799 --- [ restartedMain] o.s.boot.SpringApplication : Application startup failed

I'm currently using the following dependencies:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-couchbase</artifactId>
<version>2.1.6.RELEASE</version>
</dependency>
and
<parent>
<artifactId>spring-boot-starter-parent</artifactId>
<groupId>org.springframework.boot</groupId>
<version>1.4.2.RELEASE</version>
<relativePath />
</parent>
Thanks all for your help!
