今天想學習下CXF的開發，於是上apache官網下載了一個apache-cxf-2.7.8.zip包，解壓縮後在samples目錄下找了找，準備匯入wsdl_first_soap12專案研究下，由於這是個maven工程，於是在springsource中以maven工程方式匯入這個專案，可惜匯入就報錯了

報錯資訊：

ArtifactTransferException: Failure to transfer org.apache.cxf:cxf-rt-frontend-jaxws:jar:2.7.8 from http://192.168.19.38:8081/nexus/content/groups/public/

was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.cxf:cxf-rt-frontend-jaxws:jar:2.7.8 from/to central (http://192.168.19.38:8081/nexus/content/groups/public/): No response received after 60000

解決方式：

        執行maven update ：在package explorer檢視中右擊專案  --->   Maven  --->   Update Project  --->   點選OK

上面的錯誤沒有了，可惜專案還是報錯了

報錯資訊：

Execution generate-sources of goal org.apache.cxf:cxf-codegen-plugin:2.7.8:wsdl2java failed: Plugin org.apache.cxf:cxf-codegen-plugin:2.7.8 or one of its dependencies could not be resolved: The following artifacts could not be resolved

解決方式：

        現在再次執行maven update一直不管用，還是報錯。仔細看了下錯誤資訊，應該是pom檔案中配置的外掛的依賴包沒有下載到本地倉庫

com.sun.xml.bind:jaxb-xjc:jar:2.2.6  、  org.springframework:spring-beans:jar:3.0.7.RELEASE 、 org.springframework:spring-context:jar:3.0.7.RELEASE 、org.springframework:spring-aop:jar:3.0.7.RELEASE 、 org.apache.ant:ant:jar:1.8.4  

根據報錯資訊中提示的GAV資訊到本地倉庫中對應目錄下（如何根據GAV資訊在本地倉庫下查詢響應構件可參考http://blog.csdn.net/liuxigiant/article/details/17240283文章中倉庫佈局的說明）檢視，資料夾都存在，但是沒有jar包。所以執行幾次maven update都是沒用的。

1、刪除報錯構件的本地倉庫的儲存目錄，例如：org.springframework:spring-beans:jar:3.0.7.RELEASE構件，可以把3.0.7.RELEASE這層目錄刪除

2、執行maven update（刪除本地倉庫，maven構建專案的時候會先從本地倉庫查詢，本地倉庫沒找到才會去私服中下下載，所以本地倉庫中目錄若是存在但是jar包不存在的話，maven就不會去中央倉庫下載）

3、若某一個構件下載還是下載不下來，可以手動下載放到對應目錄下。 例如：構件jaxb-xjc-2.2.6.jar一直下載不下來，最後直接上網下載了一個jaxb-xjc-2.2.6.jar包，放到本地倉庫的對應目錄下。

現在專案終於不報錯了，可以開始研究CXF了。。。。
