为什么我不能解决GeoTools maven快速入门的依赖关系？

Question

POM是

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        </dependency>
    </dependencies>

            <url>http://download.osgeo.org/webdav/geotools/</url>
        </repository>
    </repositories>
</project>

我得到了错误：

[ERROR] Failed to execute goal on project tutorial: Could not resolve dependencies for project org.geotools:tutorial:jar:1.0-SNAPSHOT: The following artifacts could not be resolved: org.geotools:gt-shapefile:jar:10-SNAPSHOT, org.geotools:gt-swing:jar:10-SNAPSHOT: Could not find artifact org.geotools:gt-shapefile:jar:10-SNAPSHOT in maven2- repository.dev.java.net (http://download.java.net/maven/2) -> [Help 1]

为什么它不能解决这些神器。GeoTools还有其他的指令(我不能正常工作)，但是我想知道这是怎么回事。

谢谢

Answer 1

出现此问题的原因是http://download.java.net/maven/2或http://download.osgeo.org/webdav/geotools上都不存在org.geotools:gt-shapefile:jar:10-SNAPSHOT。您所要做的就是为the GeoTools:Maven Quick Start中提到的GeoTools定义snapshot repository，如下所示：

<repositories>
    <repository>
        <id>maven2-repository.dev.java.net</id>
        <name>Java.net repository</name>
        <url>http://download.java.net/maven/2</url>
    </repository>
    <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>
</repositories>

我希望这能有所帮助。

Answer 2

上述答案中的一些存储库已移动到备用地址。添加以下存储库为我解决了这个问题。

 <repository>
      <id>osgeo-alt</id>
      <url>https://repo.osgeo.org/repository/release/</url>
 </repository>
 <repository>
       <id>geomajas</id>
       <name>Geomajas Maven Repository</name>
       <url>http://maven.geomajas.org/(http://maven.geomajas.org/)</url>
 </repository>

Answer 3

当前可用的osgeo存储库：

<repository>      
  <id>geotools</id>
  <name>Geotools repository</name>
  <!--<url>http://download.osgeo.org/webdav/geotools/</url>-->
  <url>https://repo.osgeo.org/repository/geotools-releases/</url>
</repository>
