Maven 缺少工件 org.geotools:gt-shapefile:jar:11-SNAPSHOT

Question

您好，我正在尝试使用 maven 编写一个简单的 geotools 项目。其实我对maven很陌生。我打开了新的 maven 项目，设置了设置并编写了一些代码。据我所知，maven 应该下载并安装 geotools 所需的 jar 文件。但是 A 收到“缺少工件 org.geotools:gt-shapefile:jar:11-SNAPSHOT”错误，我不明白为什么会这样。

我的工作环境：

Eclipse Kepler、Jdk 6、Maven-最新版本、Geotools-最新版本

这是我的 pom.xml

这是我的快速入门课程

    package org.geotools.tutorial;

import java.io.File;

import org.geotools.data.FileDataStore;
import org.geotools.data.FileDataStoreFinder;
import org.geotools.data.simple.SimpleFeatureSource;
import org.geotools.map.FeatureLayer;
import org.geotools.map.Layer;
import org.geotools.map.MapContent;
import org.geotools.styling.SLD;
import org.geotools.styling.Style;
import org.geotools.swing.JMapFrame;
import org.geotools.swing.data.JFileDataStoreChooser;

/**
 * Prompts the user for a shapefile and displays the contents on the screen in a map frame.
 * <p>
 * This is the GeoTools Quickstart application used in documentationa and tutorials. *
 */
public class Quickstart {

    /**
     * GeoTools Quickstart demo application. Prompts the user for a shapefile and displays its
     * contents on the screen in a map frame
     */
    public static void main(String[] args) throws Exception {
        // display a data store file chooser dialog for shapefiles
        File file = JFileDataStoreChooser.showOpenFile("shp", null);
        if (file == null) {
            return;
        }

        FileDataStore store = FileDataStoreFinder.getDataStore(file);
        SimpleFeatureSource featureSource = store.getFeatureSource();

        // Create a map content and add our shapefile to it
        MapContent map = new MapContent();
        map.setTitle("Quickstart");

        Style style = SLD.createSimpleStyle(featureSource.getSchema());
        Layer layer = new FeatureLayer(featureSource, style);
        map.addLayer(layer);

        // Now display the map
        JMapFrame.showMap(map);
    }

}

我只是写了我没有下载或安装任何 jars 的代码。我将项目作为 maven 项目打开。我想知道 maven 何时以及如何下载和安装 jars？

谢谢你。

我知道这真的很旧，但在搜索问题时仍然首先出现。网址又变了，现在是：

<repository>
    <id>osgeo</id>
    <name>OSGeo Release Repository</name>
    <url>https://repo.osgeo.org/repository/release/</url>
  </repository>

或者如果您想启用快照：

  <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>

尝试将存储库 URL 替换为： http: //repo.opengeo.org/
