android – 如何覆盖Robolectric运行时依赖性存储库URL？

我们试图从我们自己的内部Nexus存储库中使用org.robolectric：robolectric：3.0依赖.问题是Robolectric尝试从公共存储库( as mentioned here)在运行时加载一些依赖项,并忽略build.gradle中的任何存储库覆盖.

由于我们无法从Intranet访问该公共位置,因此在尝试加载该依赖项后,我的测试会超时：

[WARNING] Unable to get resource
‘org.robolectric:android-all:jar:5.0.0_r2-robolectric-1’ from
repository sonatype (07001):
Error transferring file: Operation timed out

Robolectric configuration documentation的底部部分建议将其添加到Gradle配置中以覆盖URL：

android {
  testOptions {
    unitTests.all {
      systemProperty 'robolectric.dependency.repo.url','https://local-mirror/repo'
      systemProperty 'robolectric.dependency.repo.id','local'
    }
  }
}

不幸的是,我已经测试了,我从未看到系统属性被设置.我从我的自定义Robolectric跑步者(扩展RobolectricGradleTestRunner)中打印出来,并且系统属性保持设置为空.

System.out.println("robolectric.dependency.repo.url: " + System.getProperty("robolectric.dependency.repo.url"));

我也尝试过类似于this comment的东西(但在RobolectricGradleTestRunner中不存在该方法),我也尝试直接在我的自定义Robolectric运行器中设置系统属性,这似乎没有帮助.

@Config(constants = BuildConfig.class)
public class CustomRobolectricRunner extends RobolectricGradleTestRunner {
    private static final String BUILD_OUTPUT = "build/intermediates";

    public CustomRobolectricRunner(Class<?> testClass) throws InitializationError {
        super(testClass);

        System.setProperty("robolectric.dependency.repo.url","https://nexus.myinternaldomain.com/content");
        System.setProperty("robolectric.dependency.repo.id","internal");

        System.out.println("robolectric.dependency.repo.url: " + System.getProperty("robolectric.dependency.repo.url"));
    }

Robolectric source code确实似乎确认存在这些系统属性.

解决方法

虽然不是直接使用属性的修复,但另一种让它工作的方法是在RobolectricTestRunner子类中重写getJarResolver()并将其指向工件主机：

public final class MyTestRunner extends RobolectricTestRunner {
  public MyTestRunner(Class<?> testClass) throws InitializationError {
    super(testClass);
  }

  @Override protected DependencyResolver getJarResolver() {
    return new CustomDependencyResolver();
  }

  static final class CustomDependencyResolver implements DependencyResolver {
    private final Project project = new Project();

    @Override public URL[] getLocalArtifactUrls(DependencyJar... dependencies) {
      DependenciesTask dependenciesTask = new DependenciesTask();
      RemoteRepository repository = new RemoteRepository();
      repository.setUrl("https://my-nexus.example.com/content/groups/public");
      repository.setId("my-nexus");
      dependenciesTask.addConfiguredRemoteRepository(repository);
      dependenciesTask.setProject(project);
      for (DependencyJar dependencyJar : dependencies) {
        Dependency dependency = new Dependency();
        dependency.setArtifactId(dependencyJar.getArtifactId());
        dependency.setGroupId(dependencyJar.getGroupId());
        dependency.setType(dependencyJar.getType());
        dependency.setVersion(dependencyJar.getVersion());
        if (dependencyJar.getClassifier() != null) {
          dependency.setClassifier(dependencyJar.getClassifier());
        }
        dependenciesTask.addDependency(dependency);
      }
      dependenciesTask.execute();

      @SuppressWarnings("unchecked")
      Hashtable<String,String> artifacts = project.getProperties();
      URL[] urls = new URL[dependencies.length];
      for (int i = 0; i < urls.length; i++) {
        try {
          urls[i] = Util.url(artifacts.get(key(dependencies[i])));
        } catch (MalformedURLException e) {
          throw new RuntimeException(e);
        }
      }
      return urls;
    }

    @Override public URL getLocalArtifactUrl(DependencyJar dependency) {
      URL[] urls = getLocalArtifactUrls(dependency);
      if (urls.length > 0) {
        return urls[0];
      }
      return null;
    }

    private String key(DependencyJar dependency) {
      String key =
          dependency.getGroupId() + ":" + dependency.getArtifactId() + ":" + dependency.getType();
      if (dependency.getClassifier() != null) {
        key += ":" + dependency.getClassifier();
      }
      return key;
    }
  }
}

应该注意的是,这依赖于两个内部类型的Robolectric,因此在升级版本时应该小心.
