我们正在尝试使用内部Nexus存储库中的org.robolectric:robolectric:3.0
依赖项。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。
由于我们无法从内部网访问该公共位置,因此在尝试加载该依赖项后,我的测试会超时:
[警告]无法获取资源 'org.robolectric:android-all:jar:5.0.0_r2-robolectric-1'来自 存储库sonatype(https://oss.sonatype.org/content/groups/public/): 传输文件时出错:操作超时
Robolectric configuration documentation的底部会建议将其添加到您的Gradle配置中以覆盖网址:
android {
testOptions {
unitTests.all {
systemProperty 'robolectric.dependency.repo.url', 'https://local-mirror/repo'
systemProperty 'robolectric.dependency.repo.id', 'local'
}
}
}
不幸的是,我已经测试过了,我从未看到系统属性被设置。我从我的自定义Robolectric运行器(扩展RobolectricGradleTestRunner
)内部打印出来,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"));
我还尝试做类似于this comment的事情(但是这个方法不存在以在RobolectricGradleTestRunner
中覆盖),我也尝试直接在我的自定义Robolectric运行器中设置系统属性,并且这似乎没有帮助。
@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似乎确实存在这些系统属性。

虽然不是直接使用属性的修复方法,但另一种方法是通过覆盖getJarResolver()
子类中的RobolectricTestRunner
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。

您可以设置MavenDependencyResolver
使用的const addmm = x => y => array.map(maybe.of)(addm(x)(y))
arraym.chain(x => arraym.chain( addmm(x) )(arrayOfMaybes))([[10]])
mavenRepositoryId
和mavenRepositoryUrl
的属性。
示例:
RoboSettings

根据linked Github issue,一个解决方法是在settings.xml
文件夹中配置~\.m2
:
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<mirrors>
<mirror>
<id>jcenter</id>
<name>JCenter Remote</name>
<mirrorOf>*</mirrorOf>
<url>https://www.example.com/artifactory/jcenter-remote/</url>
</mirror>
</mirrors>
</settings>
<mirrorOf>*</mirrorOf>
似乎有必要强制Maven将所有存储库请求重定向到一个远程数据库。有关Maven中镜像设置的更多详细信息,请参阅here。
我发现使用远程的Sonatype是不够的,你应该使用远程的JCenter或Maven Central来获得所有的传递依赖。
答案 3 :(得分:-1)
在撰写本文时,以前的答案现在已过时。如果您引用的是最新的robolectric documentation,则需要像这样覆盖robolectric.dependency.repo.url
属性:
android {
testOptions {
unitTests.all {
systemProperty 'robolectric.dependency.repo.url', 'https://local-mirror/repo'
systemProperty 'robolectric.dependency.repo.id', 'local'
}
}
}
