一、ant eclipse 时提示Connection reset

<get src="https://downloads.sourceforge.net/project/ant-eclipse/ant-eclipse/1.0/ant-eclipse-1.0.bin.tar.bz2"

<get src="http://ufpr.dl.sourceforge.net/project/ant-eclipse/ant-eclipse/1.0/ant-eclipse-1.0.bin.tar.bz2"

二、导入工程编译之后报错‘<>’operator is not allowed for source level below 1.7

    

三、报错提示“org.apache.zookeeper.version.Info can not be resolved to a type”
