【问题描述】：
我正在尝试在 Eclipse Oxygen 中创建一个 Maven 项目，但出现了错误。这些是我所做的步骤：
- 选择文件 -> 新建 -> Maven 项目。
- 在弹出窗口中，选中“创建简单项目（跳过原型选择），并选中“使用默认工作区位置”（将位置字段留空）。
- 点击下一步。
- “Group Id”输入“com.xyz”，“Artifact Id”输入“test”，“Version”输入“0.0.1-SNAPSHOT”，“Packaging”输入“jar”。
- 将其余字段留空，单击“完成”。
项目创建时出错。在工作区日志中，我可以看到以下内容：
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6
当我打开新创建的 pom.xml 时，我可以看到一个错误：
Multiple annotations found at this line:
- CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be
resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1: ArtifactResolutionException: Failure to transfer

reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-
compiler-plugin:pom:3.1 from/to central (https://repo.maven.apache.org/maven2): sun.security.validator.ValidatorException: PKIX path building failed:

下面是我之前放在 settings.xml 中的内容，其中包含我在防火墙后面的代理设置。
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0

<nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>

看来我的主要问题与认证路径有关，如我从上述错误中提取的以下行所示。
sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
那么我该如何解决这个证书路径错误呢？
