新建app项目失败

看下你的HBuilder日志，如果错误内容是

!MESSAGE (Build null) [ERROR] Cannot assign requested address: connect  
!STACK 0  
java.net.BindException: Cannot assign requested address: connect

打开rcp.ini在最后一行加上

-Djava.net.preferIPv4Stack=true  
-Djava.net.preferIPv6Addresses=true

注意：
如果能确定你是ipv4就加第一行即可，能确定是ipv6就只加第二行
不能确定两个都加
这个是jdk1.7的问题
