Java 错误：包org.apache.commons.io.filefilter不存在

我有一个Java文件“RemoteXMLRead.Java”，其中包含以下行：

为什么javac会出现错误而不是Eclipse？

这是因为您使用Eclipse创建了这个项目，并试图使用CMD运行它。

---

当您使用eclipse时，它会自动为您添加的库生成路径和其他相关内容。因此，当您尝试使用CMD运行它时，无法正确加载库。因此，您必须手动创建项目才能使用CMD运行。

Classpath probelm。。。！您需要将Commons io jar添加到classpath中。我已将此jar文件添加到类路径“set classpath=；Commons.io_2.0.1.jar”中，但没有使用相同的问题只需通过更新jar path

javac-classpath path\to\jar\commonsio.jar RemoteXMLRead.java

@Giri尝试了此操作，但没有使用，相同的问题请尝试此操作
