I just faced the same issue and I solved it looking at Task Launcher Local example. The thing I needed to do is to add deployer local dependency to my pom file.

In particular, adding the following sentence resolved the issue:

     <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-deployer-local</artifactId>
        <version>1.3.7.RELEASE</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-core</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
