最近研究SpringBoot框架，访问http://start.spring.io/，选择构建工具Maven Project等其他工程信息，Generate Project下载项目压缩包，解压后使用eclipse，Import - Existing Maven Projects 导入项目，但是出现pom文件parent标签报错：
Description Resource Path Location Type
Project build error: Non-resolvable parent POM for com.example.demo:wh-spring-boot:1.0.2-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.M7 from https://repo.spring.io/snapshot was cached in the local repository, resolution will not be reattempted until the update interval of spring-snapshots has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.M7 from/to spring-snapshots (https://repo.spring.io/snapshot): Received fatal alert: protocol_version and 'parent.relativePath' points at no local POM pom.xml /wh-spring-boot line 14 Maven pom Loading Problem
网上找到的解决方法是在maven的settings.xml中配置阿里的mirror，然后eclipse和maven分别update
windows-preference-maven-user settings-update settings-apply
windows-show view-other-maven-mavenrRepositories,在出现的localRepository右键rebuild index
再是对项目maven-update project。
但是并未解决，索性删除本地的maven仓库，然后maven install重新下载。install success之后pom文件的parent标签不再报错，出现新的错误：
org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project.MavenProject, org.apache.maven.archiver.MavenArchiveConfiguration)网上搜索说是maven配置文件不是最新的，解决如下：
help-install new software-add-http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-mavenarchiver/0.17.2/N/LATEST/
装完之后又新的错：
web.xml is missing and <failOnMissingWebXml> is set to true继续搜索，右击项目-Java EE Tools-Generate De...在webapp-WEB-INF下创建web.xml
解决
maven的settings.xml配置如下
