Pax Exam 4和多个Maven存储库无法正常工作

Ste*_*uys 2 integration-testing osgi maven pax-exam

我正在尝试运行一个非常基本的Pax Exam 4单元测试,但需要访问多个Maven存储库(不是Maven Central).这是代码:

@RunWith(PaxExam.class)
public class ExamTest {
    @Inject
    private BundleContext bundleContext;

    @Configuration
    public Option[] config() {        
        return options(
            repositories(
                repository("http://maven.wso2.org/nexus/content/groups/wso2-public").id("wso2"),
                repository("http://nexus.codehaus.org/snapshots").id("nexus.public.repo").allowSnapshots(),
            ),
            mavenBundle("commons-httpclient.wso2", "commons-httpclient").version("3.1.0.wso2v2"),
            mavenBundle("org.codehaus.woodstox", "stax2-api").version("3.0.1-SNAPSHOT"),

            cleanCaches(),
            junitBundles()
        );
    }

    @Test
    public void testInjection() {
        Assert.assertNotNull(bundleContext);
        Bundle[] bundles = bundleContext.getBundles();
        for (Bundle bundle : bundles) {
            System.out.println(bundle.getSymbolicName() + ", state = " + bundle.getState());
        }
    }
}

实际测试是微不足道的,但仅用于测试目的,所以不要介意(repos和库也仅用于测试目的).问题是以上操作不起作用,Pax考试抱怨存储库URL无效.运行此测试时的输出如下:

[main] ERROR org.ops4j.pax.url.mvn.internal.AetherBasedResolver - invalid repository URLs
java.net.MalformedURLException: no protocol: +http://nexus.codehaus.org/snapshots/
    at java.net.URL.<init>(URL.java:585)

正如您所看到的,由于某种原因,"+"被添加到第二个URL之前,这会导致MavenConfigurationImpl中出现异常.奇怪的是,当我调试代码时,第一个URL也有一个"+",但是那个被Pax代码剥离了.然而,当字符串传递给MavenRepositoryURL构造函数时,第二个不会被剥离,然后导致MalformedURLException:

if (repositoriesProp != null && repositoriesProp.trim().length() > 0) {
    String[] repositories = repositoriesProp.split(REPOSITORIES_SEPARATOR);
    for (String repositoryURL : repositories) {
        repositoriesProperty.add(new MavenRepositoryURL(repositoryURL.trim()));
    }
}

现在这看起来像是一个错误,但我真的不相信这样一个基本选项(能够处理多个Maven回购)不起作用所以我可能做错了.那么,我的问题是:如何让Pax Exam从多个Maven存储库下载maven包?

另外:如果您只添加1个存储库,一切正常,如果您使用存储库() - 方法,则无关紧要.如果您多次使用repository()方法,结果是相同的,如下所示:

@Configuration
    public Option[] config() {        
        return options(
            repository("http://maven.wso2.org/nexus/content/groups/wso2-public").id("wso2"),
            repository("http://nexus.codehaus.org/snapshots").id("nexus.public.repo").allowSnapshots(),         
            mavenBundle("commons-httpclient.wso2", "commons-httpclient").version("3.1.0.wso2v2"),
            mavenBundle("org.codehaus.woodstox", "stax2-api").version("3.0.1-SNAPSHOT"),

            cleanCaches(),
            junitBundles()
        );
    }

这只是一个错误.

大同考试回归测试repository()选项目前不使用一个以上的仓库,并明显没有人做过.(事实上​​,处理多个外部存储库的首选方法是使用设置为镜像的存储库管理器,这样就解释了为什么这个功能可能根本不那么基本.)

Pax URL mvn:protocol handler的文档对于系统属性的语法有点过于模糊org.ops4j.pax.url.mvn.repositories.它提到了一个主要的加号,表明除了Maven的存储库之外还应使用给定的存储库settings.xml.

Pax Exam目前在每个存储库中都有一个加号,但Pax URL最多只能为整个列表加一个加号.

作为解决方法,您可以通过系统属性选项替换您的存储库选项,如下所示:

systemProperty("org.ops4j.pax.url.mvn.repositories").value("+repo1,repo2")

注意:"repo1"和"repo2"是存储库的实际URL.
