无法下载maven rependancy为*.jar文件。

Question

我试图实现来自 此处但在Maven的依赖性安装时。

我的 pom.xml 看起来像这样。

我可以下载所有的程序，除了geotools相关的程序。当我清理并运行项目时，在项目的 .m2 文件夹中，我无法看到geotool相关的jar文件。即使在maven仓库中，我也无法下载jar文件。

Maven仓库

有没有其他的方法可以进行。

Answer 1

Boundless的仓库已经被OSGeo的仓库所取代 OSGeo的webdav repo被合并到新的OSGeo repo中。 详情请看这里 (https:/docs.geotools.org最新用户指南教程quickstartmaven.html。)

替换此块

<repository>
    <id>osgeo</id>
    <name>Open Source Geospatial Foundation Repository</name>
    <url>http://download.osgeo.org/webdav/geotools/</url>
</repository>
<repository> <!--Add the snapshot repository here-->
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
    <id>opengeo</id>
    <name>OpenGeo Maven Repository</name>
    <url>http://repo.opengeo.org</url>
</repository>

与

  <repository>
    <id>osgeo</id>
    <name>OSGeo Release Repository</name>
    <url>https://repo.osgeo.org/repository/release/</url>
    <snapshots><enabled>false</enabled></snapshots>
    <releases><enabled>true</enabled></releases>
  </repository>
  <repository>
    <id>osgeo-snapshot</id>
    <name>OSGeo Snapshot Repository</name>
    <url>https://repo.osgeo.org/repository/snapshot/</url>
    <snapshots><enabled>true</enabled></snapshots>
    <releases><enabled>false</enabled></releases>
  </repository>

Answer 2

如果你贴上 Open Source Geospatial Foundation Repository 在您的浏览器中输入网址，然后点击回车，将返回 404 Not Found 错误。当Maven试图连接到该资源为你获取依赖性，但它已经不可用时，就会发生这种情况。然而，如果你密切关注 Maven Repo 链接，有一个说明。

注：此作品位于Boundless仓库(https:/repo.boundlessgeo.commain)

试着更换 http://download.osgeo.org/webdav/geotools/ 和给定的注解URL，并运行 mvn clean install

请让我知道，如果这对你有效。
