我只是用svn检查了水壶5.0，然后运行ant命令。D： \IDE\workspace\MyEclipse8.6\Kettle_5.0\build.xml正在执行，我在谷歌上搜索了一下，但帮不上忙。我该怎么处理它~~
以下是相关的错误消息：
Caused by: java.lang.IllegalArgumentException: unable to load properties from null. Tried both as an url and a file, with no success. File exception: java.lang.NullPointerException. URL exception: jav
a.net.MalformedURLException
你是否试图从URL加载常春藤文件？如果是，你能提供代码吗？我猜你正在做类似于以下结构的事情：
<ivy:settings url="${mybuild.settings.url}" />
具有未设置的ANT属性。
