我已經(jīng)在我的機(jī)器上使用 maven 好幾個(gè)月了，然后我開(kāi)始從 maven central 收到 PKIX 錯(cuò)誤，這阻止我下載適當(dāng)?shù)囊蕾図?xiàng)。> mvn compile[INFO] Scanning for projects...Downloading from central: https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.1.7.RELEASE/spring-boot-starter-parent-2.1.7.RELEASE.pom[ERROR] [ERROR] Some problems were encountered while processing the POMs:[FATAL] Non-resolvable parent POM for com.test:testproject:0.0.1-SNAPSHOT: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.1.7.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 no local POM @ line 5, column 10Maven 的完整調(diào)試輸出似乎沒(méi)有提供任何附加信息。我使用Spring Initializr上的生成器創(chuàng)建了 pom ，沒(méi)有任何其他選項(xiàng)或依賴項(xiàng)。  <?xml version="1.0" encoding="UTF-8"?>    <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 https://maven.apache.org/xsd/maven-4.0.0.xsd">        <modelVersion>4.0.0</modelVersion>        <parent>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-parent</artifactId>            <version>2.1.7.RELEASE</version>            <relativePath/> <!-- lookup parent from repository -->        </parent>        <groupId>com.test</groupId>        <artifactId>testproject</artifactId>        <version>0.0.1-SNAPSHOT</version>        <packaging>war</packaging>        <name>test</name>        <description>Demo project for Spring Boot</description>什么提供了臨時(shí)解決辦法：使用相同的pom文件在其他機(jī)器上編譯更改我的settings.xml以指向私人鏡像添加標(biāo)志以忽略證書錯(cuò)誤。盡管這些解決方法都不是必要的。什么似乎不起作用：手動(dòng)將證書安裝到 cacerts重新安裝 Java 和 Maven刪除.m2目錄（包括settings.xml）使用手動(dòng)更新指定信任庫(kù)-Djavax.net.ssl.trustStore=$JAVA_HOME/jre/lib/security/cacerts似乎可以解決問(wèn)題。我不確定為什么 Maven 默認(rèn)找不到這個(gè)文件以及如何修復(fù)它。
