IBM MobileFirst Adapters with external libraries

is there any restriction for using external libraries with java adapters in IBM MobileFirst 8.0?

When I added guava my code have no errors (mfpdev adapter build Success), but when deploying to my server it respond with error:

[ERROR] Failed to execute goal com.ibm.mfp:adapter-maven-plugin:8.0.2016082422:deploy (default-cli) on project X: The output of /mfpadmin/management-apis/2.0/runtimes/mfp/adapters is of type text/html, which is unsupported. Expected an output of type text/xml or application/xml or application/json. -> [Help 1]

But when I delete guava in pom (mvn dependencies) I am able to deploy adapter. Problem as I can see happen to some other libraries also. Is there any option to use such libraries?

mfpdev -v: 8.0.0-2017012016

EDIT: I finally resolved problem by setting scope for guava in pom file:

<scope>provided</scope>

I tried this in my MFP 8.0 environment and do not see an issue.

mfpdev -v
8.0.0-2017012016

0. Create  a sample Java adapter "mfpdev adapter create" 
1. Added dependency with guava 21 in pom.xml
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>21.0</version>
</dependency>

2. added a simple guava package and used it.

import com.google.common.base.Optional;

@GET

        @Produces(MediaType.TEXT_PLAIN)
        public String getResourceData() {
                // log message to server log
                logger.info("Logging info message...");
                Integer invalidInput = new Integer(20);
      Optional<Integer> a =  Optional.of(Input);
      Optional<Integer> b =  Optional.of(new Integer(10));
      logger.info("Logging my message with guava");
      );
        return "Hello from guava resource "+sum(a,b) ;
       }

4. build, deploy went successful

5. Access above resource 

Request URL

http://localhost:9080/mfp/api/adapters/testGuavaAdapter/resource

Response Body

Response Code
