如何设置maven安装插件的位置？

Question

我尝试使用 maven 2.2.1 构建项目并收到以下错误
请注意“无法创建目录” - 我认为原因是 D: 是由 TrueCrypt 加密的驱动器，现在实际上是 H:（D: 仍然是无法通过 Windows 访问的物理驱动器）

我该如何做让 maven 尝试将插件安装在 H: 而不是 D: 上？

您可以通过修改全局设置文件（位于 \conf\settings.xml 中）将本地存储库的位置设置为其他文件夹。然后，任何插件和工件都将安装/下载到该位置。

例如，以下代码片段将本地存储库设置为 h:\Maven\repository：

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                  http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>h:\Maven\repository</localRepository>
  ...
