無法在我的項目中正確包含PDFClown

Question

我正在嘗試第一次使用PDFClown。 按照自述文件中的說明，我嘗試通過以下步驟在Java Workspace（Eclipse IDE）中導入PDFClown Project：1）File => import ... => Existing Project to Workspace =>然后選擇下載的Java文件夾PDFClown Zip （0.1.2 Beta版）

之后，我的軟件包瀏覽器中有5個項目，其中4個由PDFClown加上我的項目。 現在，我得到38個錯誤； 最后一個與我原始項目中HelloWorld的實現有關。

編輯：對於混亂的錯誤報告，我感到抱歉，如果有人可以幫助以更友好的方式顯示它，我會很高興

編輯：實際上我已經下載了org.apache.commons.fileupload Jar，然后通過Project => Properties => Java Build Path => Libraries => Add External Jars包含了它。真的必須那么復雜嗎？

Answer 1

如果您只想在項目中包括PDF Clown，則無需導入其分發項目（其中包含完整的源代碼和預編譯的jar）：您要做的只是選擇可以在其中找到的預編譯的jar。發行版（PDFClown / java / pdfclown.lib / build / package）並將其放置在項目的依賴項中。

或者，如果您想嘗試分發樣本 （基於CLI，基於GUI和基於Web的），則必須遵循自述文件，並考慮到（如您的錯誤報告所示） 如果您要使用Web示例 （因為您已經知道Web項目的工作原理，對嗎？）， 您必須設置Web服務器 （BTW，commons-fileupload-1.2.jar已包含在該項目中，無需進行搜尋）。 如果您不了解eclipse中的Web服務器設置，請查看網絡上可用的數以萬億計的教程，否則您可以簡單地關閉eclipse中的Web示例項目（pdfclown.samples.web），這樣就不會再惹惱您了，並且您可以愉快地運行CLI和GUI示例！
