eclipse maven配置问题(pom.xml第一行报错)

1.(2018.4以前)help ->Install New Software -> add ->https://otto.takari.io/content/sites/m2e.extras/m2eclipse-mavenarchiver/0.17.2/N/LATEST
(2018.4以后)help ->Install New Software -> add -
http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-mavenarchiver/0.17.2/N/LATEST/
2.add后,先reload一下,
3.然后再在help ->Install New Software ->work with ->的下拉框中选中刚刚添加的MavenArchiver -,就会出现next选项了;
4.点击 next 前,将 eclipse Install 窗口右下角的 Contact all update sites during install to find required software 选项取消掉。
5.一直next confirm 安装更新 提示重启eclipse 然后再右键项目maven update project
