maven多仓库私库模板配置

---

尽管可以配置多个镜像服务器（mirrors），Maven 实际上仅使用其中一个作为活动节点，默认情况下，仅有首个配置的镜像服务器会被使用。具体而言，只有当首个镜像服务器无法建立连接时，Maven 才会尝试切换到下一个镜像服务器。然而，我们的期望是：如果 a.jar 在首个镜像服务器中不可得，Maven 应该能够转向列表中的第二个镜像服务器来查找并下载所需的文件，但实际上 Maven 并未按此逻辑操作。

需要注意的是，在配置多个镜像服务器时，mirrorOf 参数不应设置为 " * "。这是因为 " * " 表示匹配所有仓库（repositories），这意味着无论你配置了多少个不同的仓库，只要指定了 " * "，Maven 就会统一通过镜像服务器的地址来访问所需的构件（如某个 jar 文件）。这样一来，实际的仓库地址差异将被忽略，所有请求都将通过所指定的镜像路径进行。

使用完毕请关闭，否则每次更新maven都会非常慢。遍历所有库

    <!-- profiles
     | This is a list of profiles which can be activated in a variety of ways, and which can modify
     | the build process. Profiles provided in the settings.xml are intended to provide local machine-
     | specific paths and repository locations which allow the build to work in the local environment.
     |
     | For example, if you have an integration testing plugin - like cactus - that needs to know where
     | your Tomcat instance is installed, you can provide a variable here such that the variable is
     | dereferenced during the build process to configure the cactus plugin.
     |
     | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
     | section of this document (settings.xml) - will be discussed later. Another way essentially
     | relies on the detection of a property, either matching a particular value for the property,
     | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
     | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
     | Finally, the list of active profiles can be specified directly from the command line.
     |
     | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
     |       repositories, plugin repositories, and free-form properties to be used as configuration
     |       variables for plugins in the POM.
