在eclipse中运行测试时,NoSuchMethodError:org.hamcrest.Matchers.hasXPath

我有一个使用hamcrest库(1.2)的单元测试。重要的是它是1.2,因为我想在hasXPath匹配器中包含一个名称空间上下文。这是一个maven项目,我已经设置了所有依赖项以正确工作。(我确保我只使用junit dep而不使用junit——这很痛苦,但我已经确认了我的依赖树是正确的。)在maven中一切正常。但是,当我在eclipse(3.6)中运行相同的测试时,会得到以下错误:

java.lang.NoSuchMethodError: org.hamcrest.Matchers.hasXPath(Ljava/lang/String;Ljavax/xml/namespace/NamespaceContext;Lorg/hamcrest/Matcher;)Lorg/hamcrest/Matcher;

我已经仔细检查了项目的eclipse构建路径配置,它也有junit dep,没有junit和hamcrest 1.2。此外,没有编译错误,所以这只是运行时的事情。eclipse是否有自己的运行时干扰了这里?我该怎么解决这个问题?

导致异常的代码如下:

private NamespaceContext namespaceContext = new MetaNamespaceContext();

@Test
public void testGetPhenomenonGroupsXml() throws Exception {
    WebClient webClient = new WebClient();
    webClient.addRequestHeader("Accept", "application/xml");
    XmlPage xmlResult = webClient.getPage(BASE_URL);
    //printDoc(xmlResult.getXmlDocument(), System.out);
    assertThat("count of groups",
            xmlResult.getXmlDocument(),
            hasXPath("count(/phenomenonGroups/om:phenomenonGroup)",
                    namespaceContext, equalTo("4")));
    assertThat("first group",
            xmlResult.getXmlDocument(),
            hasXPath(
                    "/phenomenonGroups/om:phenomenonGroup/om:quickYesNoPhenomenon/id/text()",
                    namespaceContext, equalTo("1")));
}

我不确定如果没有大量的上下文(即web服务代码、完整的类代码、诸如MetaNamespaceContext之类的依赖类)这是否有用。但是,我相信,因为这一切都可以在我执行 mvn clean install 从命令行来看,这肯定是一个eclipse配置问题,与运行的特定代码没有什么关系。(当然,除了 hasXPath(String, NamespaceContext, Matcher) 方法只在1.2中可用,如果我只使用 hasXPath(String, Matcher) .
