Question

我也是Geotools和Maven的新手。我尝试使用快速入门开始使用geotools，一切正常，直到我尝试创建示例应用程序。所有以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:13.2, org.geotools:gt-swing:jar:13.2: Could not find artifact org.geotools:gt-shapefile:jar:13.2 in central (http://repo.maven.apache.org/maven2) -> [Help 1] To see the full stack trace of the errors, re-run Maven with the -e switch. Re-run Maven using the -X switch to enable full debug logging. For more information about the errors and possible solutions, please read the following articles: [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/DependencyResolutionException开头的导入都标记为不存在。寻找依赖项显示没有匹配项。这种情况发生在Netbeans和Eclipse中，显然我做错了。

在Netbeans中，我做了一个干净的构建，产生了以下结果：

<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">

有人可以帮忙吗？

使用java 1.8.0.73，Netbeans 8.1，Eclipse 4.5.1和Geotools 13.2版。我使用版本14.2得到了同样的错误。

更新 Thye pom.xml文件如下所示。

Answer 1

我无法发表评论，所以这就是我在这里回答的原因。你能告诉我们pom.xml吗？另外，你运行了mvn clean install? 在此命令之后，应该下载pom中的所有库，并且应该存在。

Answer 2

解决方案是将该部分添加到pom.xml文件中。我从教程中收集到，这在使用每晚构建时才是必需的，因为提供的pom.xml文件也没有此标记。这一切在Netbeans以及Eclipse中都很有效。正确的pom.xml如下所示：
