CXF與IncompatibleClassChangeError異常的單位測試失敗

我使用彈簧3.2.X和CXF-2.7.5CXF與IncompatibleClassChangeError異常的單位測試失敗

我進口CXF到我Spring的應用程序上下文，像這樣的應用程序：

<import resource="classpath:META-INF/cxf/cxf.xml" /> 
<import resource="classpath:cxf.xml" />

然而，當我跑我結束了以下異常測試：

從閱讀What causes java.lang.IncompatibleClassChangeError?它看起來像IncompatibleClassChangeError - 意味着我可能在我的類路徑上有衝突的庫版本。我無法從堆棧跟蹤中瞭解哪個類/庫正在被複制。

如果你還在在這裏，感謝閱讀。
我在做什麼錯？
CXF/Spring爲什麼不啓動，我該如何解決？

UPDATE：
運行調試後違規類似乎是： org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl
駐留在CXF-RT-的WS-Policy-2.7.5
至於我可以告訴雖然那是這個罐子的唯一地方，它只包含一次。

JHades更新
當我最初運行報告Log4j和Log4J的，演員是重疊的，所以是的JavaMail-1.5和Geronimo的javamail_1.4_spec。我已經解決了這些用途。

報告結果：

>>>> Jar overlap report: 


Total number of classes with more than one version: 0

兩個Jhades和mvn dependency:tree -Ddetail=true inidicate是CXF-RT-的WS-Policy是2.7.5就像所有其他的CXF JAR版本。

診斷此問題的可能方法之一是在調試器中運行您的程序，並在IncompatibleClassChangeError異常拋出時設置斷點，然後檢查局部變量以找出哪些類cxf嘗試加載。 –

所以我發現我的IDE intellij-dea搞亂了我的構建。
我認爲，因爲我配置了maven，所以它會在引擎蓋下運行純粹的maven。
在我的IDE中，我配置了一個安裝的目錄，用於Axis2-1.6.0用於我的maven依賴關係之前。 Axis-2是從我的應用程序的舊版本中遺留下來的，並且保留了許多依賴關係的重複，包括Neethi，我已經在其中列出了這個錯誤的潛在來源，其中CXF。

使用「行家依賴：樹」，找到它的依賴性使用neethi，然後排除這樣說： \t \t \t \t \t org.apache.axis2 \t \t \t Axis2的內核 \t \t \t 1.3 的javax.servlet servlet的API \t \t \t \t org.apache.neethi neethi \t \t – lordyoum

似乎正在加載的類org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl的版本無效。

您可以檢查戰爭看是否有使用此命令任何重複的課程（從JHades，一個工具，我做了），在這裏看到的duplicate classes report：

java -jar jhades-standalone-report.jar path/to/war/webapp.war

報告應該給什麼像這樣：

>>>> Jar overlap report: 

poi-3.5-FINAL-20090928.jar overlaps with poi-3.7-20101029.jar - total overlapping classes: 990 
xercesImpl-2.7.0.jar overlaps with xercesImpl-2.9.1.jar - total overlapping classes: 867 
xalan-2.6.0.jar overlaps with xalan-2.7.1.jar - total overlapping classes: 711 
bcel-5.2.jar overlaps with xalan-2.7.1.jar - total overlapping classes: 361

jasperreports-3.7.1.jar overlaps with jasperreports-applet-3.7.1.jar - total overlapping classes: 254 
... 

Total number of classes with more than one version: 6169

而且它是可以查詢的類路徑類的所有版本和當前使用的版本：

System.out.println("All versions of AssertionBuilderRegistryImpl:" + getClass().getClassLoader().getResources("org/apache/cxf/ws/policy/AssertionBuilderRegistryImpl.class")); 

System.out.println("Currently used version of AssertionBuilderRegistryImpl:" + getClass().getClassLoader().getResource("org/apache/cxf/ws/policy/AssertionBuilderRegistryImpl.class"));

存在一些可能性：存在多個版本，並且只有一個是正確的。在這種情況下，排除maven中版本錯誤的jar。

如果只有一個版本存在，那麼它的錯誤之一，使用mvn dependency:tree -Ddetail=true找出爲什麼它包括在內，並更新POM加載正確的版本。

所謂的「告密」的工具做同樣的事情（從JBoss的） –
