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

概述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 t 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.
