Question

我有一个Maven项目，我最终希望将其构建到可执行文件exe中。该项目依赖于多个库。我找到了this explanation。当我“正常”构建项目时，一切正常。使用onejar-maven-plugin后，我会遇到一些问题。

在用户界面中，我使用位于src\main\resources\UI\Icons\中的图像，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。如果我用one-jar构建，我会得到

File UI/Icons/logo.png not found!

在创建我的主框架时。使用

加载图像

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;
}

我需要告诉onejar-maven-plugin有关资源的信息吗？

您必须在资源中添加以下内容。我在下面提供了代码。

<build>
    ...
    <resources>
      <resource>
        <directory>src/resources/UI/Icons</directory>
        <includes>
          <include>**/*.png</include>
        </includes>
      </resource>
      ...
    </resources>
    ...
  </build>
