maven的xml中报错：org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project.MavenProject, org.apache.maven.archiver.MavenArchiveConfiguration)

解决方法：

1.help ->Install New Software -> add ->https://otto.takari.io/content/sites/m2e.extras/m2eclipse-mavenarchiver/0.17.2/N/LATEST
PS: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。
2.一直next confirm 安装更新提示重启eclipse 然后再右键项目maven update project
