Where is org.geotools.data.postgis?

Question

I'm trying to import WKBReader by including import org.geotools.data.postgis.WKBReader;.

The WKBReader class should be in org.geotools.data.postgis according to the documentation, but package is not available for me.

I tried to add the gt-postgis repository to pom.xml as:

<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> 
...

...but with no luck. I always get errors like:

Failed to execute goal on project tutorial: Could not resolve dependencies for project org.geotools:tutorial:jar:1.0-SNAPSHOT: Failure to find org.geotools:gt-postgis:jar:17.1 in http://download.java.net/maven/2 was cached in the local repository, resolution will not be reattempted until the update interval of maven2-repository.dev.java.net has elapsed or updates are forced -> [Help 1]

My question: where is org.geotools:gt-postgis:jar:17.1?

A quick check of the documentation shows you need the following in your pom:

<dependency>
   <groupId>org.geotools.jdbc</groupId>
   <artifactId>gt-jdbc-postgis</artifactId>
   <version>${geotools.version}</version>
 </dependency>
