我是Java Enterprise Edition的新手，我处于学习Java Servlet技术的早期阶段。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，我遇到了此问题。
导入的应用程序应用程序项目，在导入项目时在工作区构建期间预测错误。发出的错误如下。
Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project 'hello-world'.

我发现很多帖子都提到了开发人员之前遇到的这个特定问题，但由于这个错误发生在导入项目时，所描述的解决方案并没有为我的问题提供明确的解决方案。
我确实多次检查我的Maven配置，但似乎工作正常。我使用的是Java 1.8和Maven 3.2.5版本。
当我检查我导入的示例项目的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>
完整的pom.xml文件如下。

对于能够为我提供这个问题的详细解决方案的人，我将不胜感激，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。
