Maven的解决作为组识别符号公共org.apache.commons.collections的集合，并不能找到我的POM版本3.2.1

我有一个依赖：Maven的解决作为组识别符号公共org.apache.commons.collections的集合，并不能找到我的POM版本3.2.1

<dependency> 
    <groupId>commons-collections</groupId> 
    <artifactId>commons-collections</artifactId> 
    <version>3.2.1</version> 
</dependency>

恕我直言，这是正确的依赖关系（比较http://mvnrepository.com/artifact/commons-collections/commons-collections/3.2.1 ）。

但是当Maven试图解决这个问题，它试图为网址是：

这些都失败，如（恕我直言）它是错误的组ID（组织/阿帕奇/公地）。它从哪里获得URL路径中的“org/apache/commons”？

我没有其他的依赖，甚至会提及org.apache在组ID。

Maven从哪里得到这个URL？

就是这么错了，为什么就不能正确地解决它： http://central.maven.org/maven2/commons-collections/commons-collections/3.2.1/commons-collections-3.2.1.jar

？

我Maven的设置是：

Apache Maven 3.0.4 (r1232337; 2012-01-17 21:44:56+1300) 
Maven home: /home/solnet/apache-maven-3.0.4 
Java version: 1.7.0_11, vendor: Oracle Corporation 
Java home: /home/solnet/jdk1.7.0_11/jre 
Default locale: en_NZ, platform encoding: UTF-8 
OS name: "linux", version: "2.6.32-358.2.1.el6.x86_64", arch: "amd64", family: "unix"

这是我在POM文件库设置：

<repositories> 

     <repository> 
      <id>mvnrepo</id> 
      <name>mvnrepo</name> 
      <url>http://mvnrepository.com</url>

这是 “MVN帮助：有效-POM” 输出 .. 。因为看起来太大，所以请参阅：http://pastebin.com/RHAkUmMu

而这是

的输出

它在中央存储库中的权利可能在您的'pom.xml'中覆盖了存储库，导致它跳过默认存储库 – 2014-09-03 22:40:56

我也附加了我的存储库设置。 – 2014-09-03 22:56:55

从'mvn help：effective-pom'的输出粘贴库[ – 2014-09-03 22:57:45

你已经配置无效库，解决它，改变mvnrepo2<url>到http://repo1.maven.org/maven2/

这可能是真的，但如果我这样做，它仍然不能正确解析组ID。它尝试从中检索JAR的URL是：下载：http://repo.maven.apache.org/maven2/org/apache/commons/commons-collections/3.2.1/commons-collections-3.2.1.jar那仍然是错误的组ID。正确的URL可能是http://repo.maven.apache.org/maven2/commons-collections/commons-collections/3.2.1/commons-collections-3.2.1.jar – 2014-09-03 23:16:42

可能会将其从其他依赖关系中过渡拉伸，让我们找到它'mvn依赖：树-Dincludes =“org.apache.commons：commons-collections”'和''它 – 2014-09-03 23:18:51

我附加了mvn依赖项的输出：tree -Dincludes =“org.apache.commons： commons-collections“发布到底部的帖子。 – 2014-09-03 23:36:18

好了，终于这个问题的真正答案实际上是：我有另一个依赖项目，这个项目也有错误的groupid。所以当Maven构建项目时，它使用依赖项的pom来解析jar。

所以我基本上有一个级联问题，我只需要开始从底部解决问题，而不是从顶部解决问题。

感谢您提供的所有帮助！
