sikuli classpath UnsatisfiedLinkError没有opencv_core与macosx intellij Junit

Question

我之前的搜索试图找到答案，但到目前为止我的尝试失败了。我认为错误非常简单，只是没有加载类。

我正在使用intellij运行MacOSX 10。我正在使用它与Junit Spring和Maven＆amp; Junit。

我跟踪了发现mvnrepository.com - sikuli-api 1.2.0的maven依赖项，所以我在想如果将依赖项添加到pom中，那么所有文件都应该在我的类路径中？所以我不明白为什么它不起作用？

这previous answer看起来很接近我的 - 但它是用于Mac上的Windows。但是通过使用maven，我不应该将它添加到类路径？或者我错过了什么。这个similar unanswered问题看起来类似于像我一样使用mac

添加了POM依赖关系

    </dependency>

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 - ClassLoader

我跟着调试器，它在open_core的类加载器上失败 - 见截图

更新

我在下面的Samuel回答中添加了POM分类器。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 - 我试图尽可能地减少它。

Answer 1

答案基本上在README.md file，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，以获得所有平台的依赖关系。我不确定我们应该如何设置JUnit Spring（它应该在文档中），但即使这样也无法与SBT一起工作，所以为了解决这些问题，我们可以手动添加特定于平台的依赖项。由于您已在Mac OS X上运行并且对使用OpenCV 2.4.9感兴趣，因此将此附加依赖项添加到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

对于我的工作，我通过自制软件安装opencv。打开终端并输入以下内容。

brew tap homebrew/science

brew info opencv

brew install opencv

这让我的POM更小了

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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);
}
