解决maven导入geotools依赖失败的问题

maven中引入geotools依赖，如果下载不成功的话，可以尝试一下：
1、在pom文件中加入：

<repositories>
       <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>
</repositories>

2、引入geotools相关的包依赖：

        <dependency>
            <groupId>org.geotools</groupId>
            <artifactId>gt-shapefile</artifactId>
            <version>18.4</version>
        </dependency>

3、打开maven的setting.xml文件，添加一个mirror

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