sikuli classpath UnsatisfiedLinkError no opencv_core with macosx intellij Junit

Question

我以前曾进行过搜索，试图找到这个问题的答案，但到目前为止我的尝试都失败了。我认为错误很简单，只是没有加载 classes。

我是运行 MacOSX 10 with intellij。我将它与 Junit Spring 和 Maven & Junit 一起使用。

我按照找到的 Maven 依赖关系 mvnrepository.com - sikuli-api 1.2.0 所以我在想如果将依赖关系添加到 pom 那么所有文件都应该在我的 class 路径中？所以我不明白为什么它不起作用？

这个 previous answer looks close to mine - but its for windows im on a mac. However by using maven I should not need to add it to the class path?? or am I missing something. This similar unanswered 问题看起来也和我的 mac 相似

已添加 POM 依赖项

我的测试

static {
    System.setProperty("platform.dependency", "macosx-x86_64");
    //System.setProperty("platform.dependency", "1");  // tried this also
}

@Test
public void testOne() throws Exception {

    File file = new File(getClass().getClassLoader().getResource("camera_icon.png").getFile());

    browse(new URL("http://code.google.com"));

    ScreenRegion s = new DesktopScreenRegion();
    Target target = new ColorImageTarget(file);

    // ** Fails here  **
    ScreenRegion r = s.find(target); 
    ....

错误 - 类加载器

我跟踪了调试器，它在 open_core 的 class 加载器上失败了——见屏幕截图

更新

我根据下面的 Samuel 回答添加了 POM classifier。我也试过setting the system property。仍然得到同样的错误。

还注意到以下错误 - 我已尝试尽可能减少它。

Caused by: java.lang.UnsatisfiedLinkError: /private/var/folders/qp/.../libjniopencv_core.dylib: dlopen(/private/var/....../libjniopencv_core.dylib, 1): Library not loaded: @rpath/libopencv_core.2.4.dylib

Answer 1

答案基本在README.md file中，但我会在这里拼写出来。您需要将 platform.dependency 系统属性设置为所需平台，例如 macosx-x86_64，或 true platform.dependencies 系统，以获取依赖项适用于所有平台。我不确定我们应该如何使用 JUnit Spring 设置它（它应该在文档中），但即使这样也不适用于 SBT，所以为了解决这些情况，我们可以添加手动特定于平台的依赖项。由于您运行在 Mac OS X 上并且对使用 OpenCV 2.4.9 感兴趣，因此将此附加依赖项添加到您的 pom.xml 文件应该有效：

<dependency>
    <groupId>org.bytedeco.javacpp-presets</groupId>
    <artifactId>opencv</artifactId>
    <version>2.4.9-0.9</version>
    <classifier>macosx-x86_64</classifier>
</dependency>

Answer 2

为了解决我的工作，我通过自制软件安装了 opencv。打开终端并输入以下内容。

brew tap homebrew/science

酿造信息opencv

brew install opencv

这让我的 POM 变得更小

测试

@Test
public void testOne() throws IOException {

    File file = new File(getClass().getClassLoader().getResource("image_to_click.jpeg").getFile());
    browse(new URL("http://code.google.com"));

    // click image that looks like image_to_click.jpeg
    ScreenRegion s = new DesktopScreenRegion(1);
    ScreenRegion s1 = s.find(new ImageTarget(file));
    Mouse mouse = new DesktopMouse();
    mouse.click(s1.getCenter());

    // take a screenshot and save it
    BufferedImage img = s.capture();
    File outputfile = new File("screenshot_image.jpg");
    ImageIO.write(img, "jpg", outputfile);
}
