爲什麼我無法解決GeoTools maven quickstart的依賴關係？

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"> 
    <modelVersion>4.0.0</modelVersion> 

    <groupId>org.geotools</groupId>

    </properties> 

    <dependencies>

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

我得到的錯誤：

[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]

爲什麼不能解析的工件。 GeoTools有其他說明（我無法工作），但我想知道這是什麼錯誤。

感謝

問題發生的原因org.geotools:gt-shapefile:jar:10-SNAPSHOT不會在任http://download.java.net/maven/2或http://download.osgeo.org/webdav/geotools存在。所有你需要做的就是定義snapshot repository爲GeoTools，因爲它是在the GeoTools:Maven Quick Start提到以下幾點： -

<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> 

我希望這可以幫助。
