这是我的class。 Intellij 没有显示任何错误，但是当我让 ant clean all 时，那些来了：

我也将 itextpdf-5.1.0.jar 导入到 <classpathentry kind="lib" path="lib/itextpdf-5.1.0.jar"/> 但仍然相同（复制 jar 后，除了放入 .classpath 之外没有做任何其他事情）

为什么会出现错误？

None 的解决方案在网上有效。 none 其中用于 hybris。

我能做什么？我找不到 java class 的方法。我需要将给定字符串数组列表导出为 pdf。

Answer 1

默认情况下，hybris 包括在您的扩展库文件夹中找到的所有库。在您的 IDE 中，您需要自己引用库。也许您混淆了 lib 文件夹？检查您是否将库放入

\hybris\bin\custom\training\trainingcore\lib

Answer 2

您所遵循的步骤非常适合导入 external lib。

我认为您需要针对您的版本关注 itextpdf doc。最新版本 (itextpdf-5.1.0.jar) com.lowagie 不存在。您应该使用 com.itextpdf 而不是 com.lowagie

This answer 将帮助您解决问题。
