我有一个Maven项目，我最终想把它构建成一个可执行exe。此项目依赖于多个库。我找到了这个解释。当我"正常"构建项目时，一切正常。我一使用onejar-maven-plugin就会遇到一些问题。
在UI中，我使用位于srcmainresourcesUIIcons的图像，例如logo.png和logo.ico.如果我以正常方式构建代码，则会找到所有资源。万一我用one-jar构建我得到
File UI/Icons/logo.png not found!
在创建我的主框架时。图像是使用
public void test(){
String logo = "/UI/Icons/logo.png";
try {
Image image = getImageResource(this.getClass(), logo);
if (image != null) {this.setIconImage(image);}
} catch (IOException ex) {
System.err.println("File " + logo + " not found!");
}
}
public static Image getImageResource( Class base, String name ) throws java.io.IOException {
Image result = null;
URL imageURL = base.getClassLoader().getResource( name );
if ( imageURL != null ) {
Toolkit tk = Toolkit.getDefaultToolkit();
result = tk.createImage( (ImageProducer) imageURL.getContent() );
}
return result;
}
关于资源，我有什么要告诉onejar-maven-plugin的吗？
