java.lang.NoSuchFieldError：創建球衣休息客戶端時的WADL_JSON

我正在用jackson pojo mapping創建jersey rest客戶端。這裏是代碼尖晶石：java.lang.NoSuchFieldError：創建球衣休息客戶端時的WADL_JSON

ClientConfig clientConfig = new DefaultClientConfig(); 
    clientConfig.getClasses().add(JacksonJsonProvider.class); 
    clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE); 
    client = Client.create(clientConfig); 
    webResource = client.resource("url to exposed rest web service");

這個代碼是在拋繩以下異常client = Client.create(clientConfig)

我使用下列jar：

jackson-core-asl:1.9.13
jackson-jaxrs:1.9.13
jackson-xc:1.9.13
jersey-client:1.1.5.1

我受夠了搜索google and stackoverflow，但找不到任何解決方案。如果有人遇到同樣的錯誤並解決問題，請提出一些解決方案。

請格式化您的問題中的代碼 – CocoNess 2014-09-01 08:04:53

我得到了問題的解決方案。這是由於jar衝突。我將jersey-client：1.1.5.1更改爲jersey-client：1.18
