Java 在Eclipse中创建Maven项目时出现证书路径错误

我试图在EclipseOxygen中创建一个Maven项目，但结果出现了错误。以下是我所做的步骤：

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）

单击下一步

输入“com.xyz”表示“组Id”，“test”表示“工件Id”，“0.0.1-SNAPSHOT”表示“版本”，输入“jar”表示“打包”

将其余字段留空，单击Finish

创建项目时出错。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

下面是我之前在settings.xml中的内容，它包含代理设置，因为我在防火墙后面

    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

那么如何解决此认证路径错误？

以下是与您的问题类似的线程，您正在尝试连接到https远程存储库-“”。

大多数情况下，支持HTTPS连接的证书未包含在cacerts文件中。

谢谢。我在那里使用了答案，在settings.xml中更改为http maven repository，它可以工作。欢迎您：）并感谢您接受答案：）如果您想包含证书，这非常简单。
