我正在创建我的 build.xml 文件来用 ant 构建我的 jar。
除了将外部资源作为图像加载之外，一切都很完美。
我想做的就是了解如何以正确的方式创建 jar。实际上我的代码是：
我知道问题出在包含以下内容的每一行： this.getClass().getResource("/img/logo150.png") （我对此很担心，因为我通过日志记录和调试单独测试了每一行，问题出在那）
但我不明白为什么。我尝试了数百种可能性，罐子的许多不同设置，我在 stackoverflow 中尝试了许多不同的答案，但没有解决方案奏效。
我正在使用eclipse，文件夹结构是：
src -> source code
res -> img -> images
res -> config.files.txt
db -> database files
lib -> libs
有什么想法吗？如果我运行项目，代码可以完美运行，但是当我运行 ant 构建（运行方式）时它不起作用。
编辑：哦，是的，我终于可以发布代码了！

第二个问题：
encoding= 8859_1
这行不是我写的。但我的编码有问题（在罐子里我看不到欧元符号）我应该设置什么价值之王？
第三
java项目（也在eclipse中）是否有任何“正确”或“标准”文件夹结构，或者我的项目进展顺利？（还有许多不同的路径）
