spring-cloud-config: In STS, sleuth causes the compile error: Build path is incomplete. Cannot find class file for org/tmatesoft/svn/core/wc2/SvnOperationFactory

Hi,

I have a config server application and all were fine until I added spring-cloud-starter-sleuth which is causing a compilation error:

Build path is incomplete. Cannot find class file for org/tmatesoft/svn/core/wc2/SvnOperationFactory

the important part of my pom:

      <dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-server</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-security</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-amqp</artifactId>
		</dependency>
   		<dependency>
       		        <groupId>org.springframework.cloud</groupId>
        	        <artifactId>spring-cloud-starter-sleuth</artifactId>
   		 </dependency>
	</dependencies>

      <dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Camden.SR5</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

My spring boot version is: 1.5.1.RELEASE

Any help?
