java - 无法在我的项目中正确包含 PDFClown

Question

我是第一次尝试使用 PDFClown。正如自述文件中所写，我尝试通过以下步骤导入 PDFClown 项目在我的 Java 工作区 Eclipse IDE 中1) 文件 => 导入... => 将现有项目导入工作区 => 然后我选择了下载的 Java 文件夹 PDFClown Zip (版本0.1.2 Beta)

此后，我的包资源管理器中有 5 个项目，其中 4 个由 PDFClown 加上我的项目拥有。现在，我收到 38 个错误；最后一个与我原始项目中 HelloWorld 的实现相关。

编辑:我对困惑的错误报告感到抱歉，如果有人可以帮助以更友好的方式显示它，我会很高兴

编辑:实际上我已经下载了 org.apache.commons.fileupload Jar，然后通过继续 Project => Properties => Java Build Path => Libraries => Add external Jars 来包含它现在我的错误减少了，但是......它真的必须那么复杂吗？

Answer 1

如果您只想在项目中包含 PDF Clown，则无需导入其分发项目(其中包含完整源代码和预编译的 jar):您所要做的只是选择预编译的 jar 您可以在发行版 (PDFClown/java/pdfclown.lib/build/package) 中找到并将它们放入项目的依赖项中。

或者，如果您想尝试分发示例(基于 CLI、基于 GUI 和基于 Web)，那么您必须遵循自述文件，考虑到(作为您的错误报告显示)如果您想使用 Web 示例(因为您已经知道 Web 项目如何工作，对吧？)您必须设置您的 Web 服务器(顺便说一句， commons-fileupload-1.2.jar 已经包含在项目中，无需寻找)。如果您不知道 Eclipse 中的 Web 服务器设置，那么请查看网络上提供的万亿教程，否则您可以简单地关闭 Eclipse 中的 Web 示例项目(pdfclown.samples.web)，这样它就不会再让您烦恼了您可以愉快地运行 CLI 和 GUI 示例!
