Answer 1

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>
