Maven将commons-collections groupid解析为org.apache.commons.collections，并且找不到版本3.2.1

Question

在我的pom中，我有一个依赖项：

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

IMHO这是正确的依赖关系(比较http://mvn repository . com/artifact/commons-collections/commons-collections/3 . 2 . 1)。

但是，当Maven尝试解决此问题时，它尝试的URL是：

Downloading: http://mvnrepository.com/org/apache/commons/commons-collections/3.2.1/commons-collections-3.2.1.pom

这些都失败了，因为（恕我直言）它是错误的组ID（org/apache/公共资源）。它从哪里获得URL路径中的“org/apache/公共资源”？

我没有其他依赖项会在组id中提到org.apache。

Maven从哪里获得此网址？

这是如此错误，为什么它不能正确地解决它：http://central.maven.org/maven2/commons-collections/commons-collections/3.2.1/commons-collections-3.2.1.jar

?

我的Maven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

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文件中的存储库设置:

    <repositories>

        <repository>
            <id>mvnrepo</id>
            <name>mvnrepo</name>

        </repository>

         <repository>

            <name>centralmvn</name>

        </repository>
        <repository>

            <name>CodeHaus Releases</name>
            <url>http://repository.codehaus.org/</url>
        </repository>

   /repositories>

这是输出的"mvn帮助：有效的pom"…

这是

mvn依赖：tree-Dincludes=“org.apache.commons:commons集合”

Answer 1

好吧，最后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。因此，当Maven构建项目时，它使用依赖项的pom来解析jar。

所以我基本上遇到了一个级联问题，我只能从底部开始解决问题，而不是从顶部开始。

感谢所有提供的帮助！

您配置了无效的存储库，要修复它，请更改
