英文:
Project build error: Non-resolvable parent POM - Spring boot
问题
以下是翻译好的部分：
我尝试创建一个Spring Boot项目，但是当我在pom文件中放入<parent>依赖时，出现了一个错误。我已经尝试访问http://repo.spring.io网址，它是可以访问的。我尝试更改了代理设置，但问题没有解决。我甚至删除了settings.xml并进行了检查。
我在下面提到了我的Maven和JDK版本。
Maven安装目录：C:\Program Files\apache-maven-3.6.3-bin*apache-maven-3.6.3*\bin..
Java版本：15.0.1，供应商：Oracle Corporation，运行时：C:\Program Files\Java*jdk-15.0.1*
以下是我的pom文件依赖项。
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>com.dm.boot</groupId>
<artifactId>springboot-demo</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>Springboot Demo App</name>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.6.RELEASE</version>
</parent>
以下是我的settings.xml。
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0

<username>proxyuser</username>
<password>somepassword</password>
<nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
</proxy>
</proxies>

尝试在 ~/.m2/settings.xml 文件中指定实际的代理主机和端口，如果可以在不指定用户名和密码的情况下建立连接，请删除用户名和密码。
<host>在这里填入您的代理主机</host>
<port>在这里填入您的代理端口</port>
如果建立连接需要用户名和密码，请使用实际的凭据进行配置：
<host>在这里填入您的代理主机</host>
<port>在这里填入您的代理端口</port>
<username>在这里填入您的用户名</username>
<password>在这里填入您的密码</password>
英文:
Try specifying your actual proxy host and port in the ~/.m2/settings.xml and remove the username and password if you can establish the connection without specifying username and password.
<host>Your Proxy Host Here</host>
<port>Your Proxy Port Here</port>
If both username and password is required to establish the connection, use your actual credentials like this:
<host>Your Proxy Host Here</host>
<port>Your Proxy Port Here</port>
<username>Your Username Here</username>
<password>Your Password Here</password>
