ANT創建jar文件，給getResource +編碼帶來問題

Question

我正在創建我的build.xml文件來構建我的jar與ant。

除了將外部資源加載爲圖像之外，所有這一切都是完美的。

我想要做的就是了解如何以正確的方式創建jar。其實我的代碼是：

我知道，問題是包含每行： this.getClass（）的getResource（「/ IMG/logo150.png」） （我舒爾這一點，因爲我每次測試一個單獨與日誌記錄和調試，問題在於）

但我不明白爲什麼。我嘗試了數百種可能性，很多不同的jar設置，我在這裏嘗試了很多不同的答案，但沒有解決方案。

我使用Eclipse和文件夾結構：

src -> source code 
res -> img -> images 
res -> config.files.txt 
db -> database files 
lib -> libs 

任何想法？如果我運行該項目，代碼完美工作，但是當我運行ant build（Run as）時，它不起作用。

編輯：噢，最後我可以發佈代碼！

第二個問題：

encoding= 8859_1 

此行是不是我寫的。但我有編碼問題（在罐子裏我看不到歐元辛博爾）我應該設置什麼樣的價值王？

第三

是否有任何「正確」或「非標準」文件夾中的Java項目結構（Eclipse還）或我跟我的很順利？ （也有許多不同的路徑）

Answer 1

使用這樣的事情：

<copy todir="${yourJarFolder}/folder"> 
    <fileset dir="${basedir}/folder" includes="**" /> 
</copy> 

此代碼副本，您在您的工作有直接的罐子的文件夾中，而不是罐子裏面的文件夾，但相同的文件夾。

之後，您可以使用不使用getResource（）的標準方法訪問任何資源。

希望它適合你。
