无法在错误的本地 POM 上找到请求的目标和"parent.relativePath"点的有效认证路径



我正在尝试使用 maven Spring 库并按照本教程构建 java 中的微服务(eclipse(的概念证明。

下面是我的POM文件,它显示了一个我无法解决的错误:

<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.tutorials</groupId>
<artifactId>HelloWorld</artifactId>
<version>0.0.1-SNAPSHOT</version>

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.0.RELEASE</version>
</parent>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</project>

在标签<parent>上,我有以下错误:

Project build error: Non-resolvable parent POM for com.tutorials:HelloWorld:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:
1.2.0.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has 
elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.2.0.RELEASE from/to central (https://
repo.maven.apache.org/maven2): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to 
find valid certification path to requested target and 'parent.relativePath' points at wrong local POM

如何解决此问题?谢谢。

编辑:在目录User/.m2中,我创建了一个设置.xml文件来克服代理问题,如下所示:

<settings>
<proxies>
<proxy>
<id>example-proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>proxy.example.com</host>
<port>8080</port>
<nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
</proxy>
</proxies>
</settings>

现在错误如下:

Project build error: Non-resolvable parent POM for com.tutorials:HelloWorld:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:
2.2.2.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has 
elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.2.2.RELEASE from/to central (https://
repo.maven.apache.org/maven2): proxy.example.com and 'parent.relativePath' points at wrong local POM

问题是证书未安装在您的 java 安全性中。正如您提到的,您可以访问 https://repo.maven.apache.org/maven2/如果您使用的是 Chrome,则需要从网站信息中导出证书。

之后,您需要在密钥库中安装证书, 在以下情况下:

Java 8 : JDK->JRE->lib->security

Java 11 : JDK->lib->security

安装证书的命令:

keytool -import -noprompt -trustcacerts -alias -file -keystore -storepass

这个问题在 2 年前就被问过了,但希望有人能从中得到帮助。
