帶有外部庫的IBM MobileFirst適配器

Question

在IBM MobileFirst 8.0中對使用Java適配器的外部庫有沒有限制？

當我加入guava我的代碼沒有錯誤（mfpdev適配器建立成功），但部署到我的服務器時，它與錯誤迴應：

[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] 

當我刪除POM番石榴（MVN依賴）我可是我能夠部署適配器。我也可以看到其他一些圖書館也遇到問題。有沒有選擇使用這種庫？

mfpdev -v：8.0.0-2017012016

<scope>provided</scope>

我在MFP 8.0環境中嘗試這樣做，我終於在POM文件中設置範圍爲番石榴解決問題沒有看到問題。

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 

Hello from guava resource 30 

Response Code
