首先是配置：

Apache Maven 3.0.4 (r1232337; 2012-01-17 12:44:56+0400)
Java version: 1.7.0_04, vendor: Oracle Corporation
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac"
Nexus repository: 2.0.6

<modelVersion>4.0.0</modelVersion>

<name>Parent POM</name>

<artifactId>parent-pom</artifactId>
<version>0.1-SNAPSHOT</version>
<packaging>pom</packaging>

<build>

                </configuration>

<modules>

    <module>projA</module>
    <module>projB</module>

</modules> 

<modelVersion>4.0.0</modelVersion>

<name>Project A</name>
<groupId>my.com</groupId>
<artifactId>projA</artifactId>
<version>0.1-SNAPSHOT</version>

<parent>
    <groupId>my.com</groupId>
    <artifactId>parent-pom</artifactId>
    <version>0.1-SNAPSHOT</version>
    <relativePath/>        
</parent>

<name>Project B</name>
<groupId>my.com</groupId>
<artifactId>projB</artifactId>
<version>0.1-SNAPSHOT</version>

<parent>
    <groupId>my.com</groupId>
    <artifactId>parent-pom</artifactId>
    <version>0.1-SNAPSHOT</version>
    <relativePath/>        
</parent> 

下面是我运行“MVN清洁站点”的文件夹的结构：

./pom.xml  (aggregation project)
./projA/pom.xml (Project A)
./projB/pom.xml (Project B)

在执行MVN clean Site之前，通过以下命令成功地将parent-pom部署到NEXUS存储库中MVN deploy-daltdeploymentrepository=snapshots::default::http://myserver:8081/NEXUS/content/repositories/snapshots

最后是问题本身：

谢谢你。

Answer 1

正如这个答案所指出的，站点插件中有一个bug，它只在它认为是Maven Central的地方寻找依赖项。

我在Maven3.0.4和site-plugin3.3中也遇到了同样的问题。我也有一个问题，它在我的开发机器上运行Windows7，但不能在CI-Server上运行Jenkins在Debian上。
