Ant在javac没有消息就失败了(Ant fails without message at javac)

 我编写了一个Ant build.xml文件，它通过WSDL获取了许多源文件并编译它们。 这些系统一直处理旧的，现在被破坏（因此无法进行比较）的系统，但是在这个更新，更快的系统上，构建过程没有完成。 
 
 构建文件的相关部分如下所示（已更新）： 
 
<target name="obtain-files">
  <java classname="org.apache.axis.wsdl.WSDL2Java">
    <arg line="--all --server-side --skeletonDeploy --factory --wrapArrays --output src ${srcurl}" />
  </java>
</target>

<target name="compile" depends="obtain-files">
  <javac srcdir="${src}" destdir="${build}" verbose="yes" />
</target>
 
 成功通过WSDL服务下载/创建.java文件，但在此之后，Ant只会停止并返回命令行。 
 
 相关应用的版本： 
 
# java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode)
# javac -version
javac 1.6.0_14
# ant -version
Apache Ant version 1.6.5 compiled on January 6 2007
 
 我假设有一个问题，javac Ant没有传回来。 有什么方法可以从javac获取一些调试信息吗？ 我已经尝试将<record />标记添加到目标但是这不会提供比运行ant -v更多的信息。 
 
 任何其他建议也会很棒！ 

I've written an Ant build.xml file which obtains a number of source files via WSDL and compiles them. These have been working on an old, now destroyed (and therefore unavailable for comparison), system but the build process isn't completing on this newer, faster system.
 
The relevant section of the build file looks like this (updated):
 
<target name="obtain-files">
  <java classname="org.apache.axis.wsdl.WSDL2Java">
    <arg line="--all --server-side --skeletonDeploy --factory --wrapArrays --output src ${srcurl}" />
  </java>
</target>

<target name="compile" depends="obtain-files">
  <javac srcdir="${src}" destdir="${build}" verbose="yes" />
</target>
 
The .java files are downloaded/created via the WSDL service successfully, however after that point Ant simply stops & returns to the commandline.
 
Versions of the relevant apps:
 
# java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode)
# javac -version
javac 1.6.0_14
# ant -version
Apache Ant version 1.6.5 compiled on January 6 2007
 
I'm assuming that there's a problem with javac that Ant isn't passing back. Is there any way I can get some debugging information from javac? I've tried adding a <record /> tag to the target but that doesn't give any more information than running ant -v does.
 
Any other suggestions would be great, also!
