我对JavaEnterpriseEdition完全陌生，我正处于学习JavaServlet技术的早期阶段。我在将现有Java web应用程序示例项目导入Eclipse Lunar Java EE IDE的过程中遇到了这个问题

导入的应用程序项目在导入项目时，在构建工作区期间投影错误。发出的错误如下所示

我发现很多帖子都提到了开发人员以前遇到过的这个问题，但是由于这个错误发生在导入项目的时候，所描述的解决方案并没有为我的问题提供一个明确的解决方案

我确实检查了我的Maven配置好几次，但它似乎工作得很好。我使用的是Java1.8和Maven 3.2.5版本

当我检查导入的示例项目的pom.xml文件时，错误指向以下xml代码片段

     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
     </plugin>

我非常感谢任何能为我提供这个问题的详细解决方案的人，因为这是我第一次面对Maven依赖项的使用和Java web应用程序的构建

错误消息表示找不到某个插件依赖项。你能添加完整的pom.xml吗？我已经添加到我的问题中了。你的pom看起来不错。您是否手动配置了要使用的存储库？在Eclipse中，当我查看我的首选项时，我发现M2_REPO classpath变量已经设置到系统中的某个位置。我没有手动设置。1。在Eclipse中Windows-->首选项中Maven下的用户设置中，现有路径指的是指定位置中似乎不存在的Settings.xml文件。Maven安装的conf文件夹中存在settings.xml。2.settings.xml文件几乎所有的编码都有注释，包括，这可能是原因吗？我应该编辑和配置settings.xml文件吗？我将非常感谢任何帮助，因为我是Maven的新手…错误消息表明找不到某个插件依赖项。你能添加完整的pom.xml吗？我已经添加到我的问题中了。你的pom看起来不错。您是否手动配置了要使用的存储库？在Eclipse中，当我查看我的首选项时，我发现M2_REPO classpath变量已经设置到系统中的某个位置。我没有手动设置。1。在Eclipse中Windows-->首选项中Maven下的用户设置中，现有路径指的是指定位置中似乎不存在的Settings.xml文件。Maven安装的conf文件夹中存在settings.xml。2.settings.xml文件几乎所有的编码都有注释，包括，这可能是原因吗？我应该编辑和配置settings.xml文件吗？我将非常感谢任何帮助，因为我是Maven的新手…错误消息表明找不到某个插件依赖项。你能添加完整的pom.xml吗？我已经添加到我的问题中了。你的pom看起来不错。您是否手动配置了要使用的存储库？在Eclipse中，当我查看我的首选项时，我发现M2_REPO classpath变量已经设置到系统中的某个位置。我没有手动设置。1。在Eclipse中Windows-->首选项中Maven下的用户设置中，现有路径指的是指定位置中似乎不存在的Settings.xml文件。Maven安装的conf文件夹中存在settings.xml。2.settings.xml文件几乎所有的编码都有注释，包括，这可能是原因吗？我应该编辑和配置settings.xml文件吗？我将非常感谢任何帮助，因为我是新的Maven。。。
