Java 如何将maven依赖项下载为*.jar文件？

我试图从中实现该示例，但在安装Maven dependencies时，在下载的依赖项中找不到jar文件

我的

pom.xml

如下所示：

是否有其他方法可供选择？
 < P>如果你在网页浏览器中粘贴<代码>开源地理空间知识库< /代码> URL并点击回车，它将返回<代码> 404未找到错误。当Maven试图连接到该资源为您获取依赖项，但它不再可用时，就会发生这种情况。但是，如果您密切关注
Maven Repo
链接，请注意：

注意：此人工制品位于无限存储库（）

尝试替换
http://download.osgeo.org/webdav/geotools/
使用注释URL中的给定值运行
mvn clean install

请让我知道这是否对您有效。
由Boundless运行的存储库已被OSGeo托管的存储库取代。OSGeo webdav回购合并为新的OSGeo回购。详情如下（）
