CXF failing with IncompatibleClassChangeError exception on Unit Test
提问by Raystorm
I have an application using Spring-3.2.Xand cxf-2.7.5
我有一个使用Spring-3.2.X和cxf-2.7.5的应用程序
I'm importing cxf into my spring's app context like so:
我将 cxf 导入到我的 spring 应用程序上下文中，如下所示：
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:cxf.xml" />
However, When I run the tests I end up with the following exception:
但是，当我运行测试时，我最终遇到以下异常：

From reading What causes java.lang.IncompatibleClassChangeError?it looks like IncompatibleClassChangeError- Means I probably have conflicting library versions on my classpath. I can't tell from the stack trace which class/library is being duplicated.
从阅读什么原因导致 java.lang.IncompatibleClassChangeError？它看起来像IncompatibleClassChangeError- 意味着我的类路径上可能有冲突的库版本。我无法从堆栈跟踪中分辨出哪个类/库正在被复制。
My POM looks like so:

If you're still here, thanks for reading.
What am I doing wrong?
Why won't CXF/Spring start, and how do I fix it?
如果您还在这里，感谢您的阅读。
我究竟做错了什么？
为什么 CXF/Spring 无法启动，我该如何解决？
UPDATE:
After running the debugger the offending class appears to be:
org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl
which resides in cxf-rt-ws-policy-2.7.5
As far as I can tell though that's the only place for that jar and It's only included once.
更新：
运行调试器后，有问题的类似乎是：
org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl
它驻留在cxf-rt-ws-policy-2.7.5 中，
据我所知，虽然这是该 jar 的唯一位置，但它只包含一次。
JHades Update
When I initially ran the report Log4J and Log4J-extras were overlapping, so was
JavaMail-1.5 and geronimo-javamail_1.4_spec. I've resolved those uses.
JHades 更新
当我最初运行报告时，Log4J 和 Log4J-extras 重叠，JavaMail-1.5 和 geronimo-javamail_1.4_spec 也是如此。我已经解决了这些用途。
report results:
报告结果：
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"));
Both Jhadesand mvn dependency:tree -Ddetail=trueinidicate that cxf-rt-ws-policyis 2.7.5just like every other cxf jar version.
无论Jhades和mvn dependency:tree -Ddetail=trueinidicate那CXF-RT-的WS-Policy是2.7.5就像所有其他的CXF JAR版本。

So I it turns out my IDE intellij-deawas messing up my build.
I thought that since I had maven configured, that it would just be running pure maven, under the hood.
In my IDE I had configured an installed Directory for Axis2-1.6.0to be used before my maven dependencies. Axis-2 was left over from an OLD version of my application and held duplicates of a lot dependencies including something called Neethi, which I've seen listed else where as a potential source of this error with CXF.
所以我发现我的 IDE intellij-dea搞砸了我的构建。
我想，既然我已经配置了 maven，它就会在引擎盖下运行纯 maven。
在我的 IDE 中，我为Axis2-1.6.0配置了一个安装目录，以便在我的 maven 依赖项之前使用。Axis-2 是我的应用程序的旧版本遗留下来的，并保留了许多依赖项的重复项，包括称为Neethi 的东西，我在其他地方看到它列为CXF错误的潜在来源。
回答by Angular University
It seems the version of class org.apache.cxf.ws.policy.AssertionBuilderRegistryImplthat is being loaded is invalid.
似乎org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl正在加载的类的版本无效。
You can check the WAR to see if there are any duplicate classes using this command (from JHades, a tool I've made), see here for the duplicate classes report:
您可以使用此命令检查 WAR 以查看是否有任何重复的类（来自JHades，我制作的工具），请参见此处的重复类报告：
##代码##The report should give something like this:
报告应该给出如下内容：
##代码##Also it's possible to query the classpath for all versions of the class and for the currently used version:
也可以查询类的所有版本和当前使用的版本的类路径：
##代码##There are a couple of possibilities: either multiple versions exist, and only one is correct. In that case exclude the jars with the wrong versions in maven.
有几种可能性：要么存在多个版本，要么只有一个是正确的。在这种情况下，排除 Maven 中版本错误的 jar。
If only one version exists, then it's the wrong one, use mvn dependency:tree -Ddetail=trueto find why it's included, and update the pom to load the correct version.
如果只存在一个版本，那么它是错误的，用于mvn dependency:tree -Ddetail=true查找为什么包含它，并更新 pom 以加载正确的版本。
