org.geotools.data.postgis在哪里?

import org.geotools.data.postgis.WKBReader; .

WKBReader类应在 org.geotools.data.postgis according to the documentation ,但我没有这个包裹。

我试图将gt postgis存储库添加到 pom.xml

<properties>
   <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   <geotools.version>17.1</geotools.version>
</properties>
...
<dependency>
    <groupId>org.geotools</groupId>
    <artifactId>gt-postgis</artifactId>
    <version>${geotools.version}</version>
</dependency> 
...

…但运气不好。我总是会出现以下错误:

http://download.java.net/maven/2 已缓存在本地存储库中,在maven2-repository.dev.java的更新间隔之前不会重新尝试解析。net已过期或强制更新->[帮助1]

我的问题是:在哪里 org.geotools:gt-postgis:jar:17.1 ?
