带有外部库的 IBM MobileFirst 适配器

Question

在 IBM MobileFirst 8.0 中使用带有 java 适配器的外部库是否有任何限制？

当我添加guava 时，我的代码没有错误（mfpdev 适配器构建成功），但是在部署到我的服务器时它响应错误：

[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]

但是当我在 pom（mvn 依赖项）中删除番石榴时，我能够部署适配器。我看到的问题也发生在其他一些库上。有没有使用这些库的选项？

mfpdev -v: 8.0.0-2017012016

编辑：我终于通过在 pom 文件中设置番石榴的范围来解决问题：

<scope>provided</scope>

我在我的 MFP 8.0 环境中尝试过，没有发现问题。

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
