我有一个虚拟机,我正在使用 spring 工具套件和 JDK7。
我已经从 git 下载了我的项目,但在 pom.xml 中出现错误:
Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its dependencies could not be resolved:
Failed to read artifact descriptor for org.apache.maven.plugins:maven-clean-plugin:jar:2.5:
Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (http://repo.maven.apache.org/maven2):

小米pom.xml

测试过。删除.m2,maven clean,...
我需要改变什么?
