Run As Maven test时
1.提示deploy, compiler等错误，
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6
Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6
是因为仓库中的版本不正确或以前下载出错，删除仓库中此文件夹，重新Maven->update project
C:\Users{username}.m2\repository\org\apache\maven\plugins
2.提示jre/../tools.jar不存在，修改项目的默认jre路径为/jdk/jre/
修改为jdk下的jre
