为什么CXF WSDLToJava的Ant/Ivy集成不起作用？

Question

我想使用WSDLToJava的Apache的CXF在我的Ant构建文件从WSDL创建Java代码.使用Ivy解决依赖关系.我总是得到以下错误:

WSDLToJava Error: Could not find jaxb databinding within classpath

我没有安装,想用Ivy为我做这个工作.这是我的Ant构建文件的一部分:

<target name="generate" depends="init">
  <ivy:retrieve conf="build"/>
  <mkdir dir="${basedir}/target/generated"/>
  <ivy:cachepath pathid="build-classpath" conf="build"/>
  <java classname="org.apache.cxf.tools.wsdlto.WSDLToJava" fork="true">
    <arg value="-d"/>
    <arg value="${basedir}/target/generated"/>
    <arg value="-client"/>
    <arg value="${basedir}/src/schema/MyWebService.wsdl"/>
    <classpath refid="build-classpath"/>
  </java>
</target>

我使用Java 6,Ant 1.8,Ivy 2.2.0 ant CXF 2.2.12.在常春藤模块中,我配置了以下内容:

<configurations>
  <conf name="build" visibility="private"/>
  ...
</configurations>

<dependencies defaultconfmapping="*->default">
  <dependency org="org.apache.cxf" name="cxf-tools-wsdlto-frontend-jaxws" rev="2.2.12" conf="build"/>
  <dependency org="org.apache.cxf" name="cxf-rt-databinding-jaxb" rev="2.2.12" conf="build"/>
  ...
</dependencies>

问题出在哪儿？也许有一个依赖缺失,但哪一个？如果没有Ivy,Ant集成将使用包含CXF安装的所有jar的类路径.如果我这样做,它的确有效.

在构建的输出中,我看到以下内容:

Answer 1

cxf-tools-wsdlto-databinding-jaxb您可能还需要一个依赖项.出于各种原因,工具和运行时对于JAXB是独立的.
