事情源于: 在Mac上pull下来的项目和本地的不一致, 所以在终端重命名了项目,并从github上clone了一份.
这期间IDEA一直是开的,所以重命名时,项目会被自动删除,clone后又出现了.
但是这时IDEA已经无法认识这个clone下来的项目是Maven项目. 于是蛋疼的一幕出现了.
问题出现: 无法导入Maven项目
问题: Import Maven Module选择Maven项目导入后, looking for available profiles
过了一会儿还是在当前窗口,没有任何反应.
首先找到Idea在Mac下的日志位置:

根据这篇帖子, 设置127.0.0.1 localhost仍然不行(其他方法比如设置Maven的-Didea.maven3.use.compat.resolver).

重装不是万能的
只好重装Idea了(覆盖安装仍然不行!).完全卸载IDEA,要删除它的配置文件等.
商业版本(比社区版多了IntelliJ):
➜ ~ rm -rf Library/Preferences/IntelliJIdea14
➜ ~ rm -rf Library/Caches/IntelliJIdea14
➜ ~ rm -rf Library/Application\ Support/IntelliJIdea14
➜ ~ rm -rf Library/Logs/IntelliJIdea14
社区版本(少了IntelliJ,多了IC):
➜ ~ rm -rf Library/Preferences/IdeaIC14/
➜ ~ rm -rf Library/Caches/IdeaIC14
➜ ~ rm -rf Library/Application\ Support/IdeaIC14
➜ ~ rm -rf Library/Logs/IdeaIC14
但是, 重装就一定能解决问题吗? WRONG QUESTION!!!
IPv6问题是怎么出现的
Mac下IDEA的配置文件idea.vmoptions的路径是:
/Applications/IntelliJ IDEA 14 CE.app/Contents/bin
一般软件在mac的HOME是以Contents, 比如JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
添加IPV4的优先级: https://intellij-support.jetbrains.com/hc/en-us/articles/206827597-Net...
➜ bin cat idea.vmoptions
-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=225m
-XX:+UseCompressedOops
-Djava.net.preferIPv4Stack=true
重启. 重新导入一个Maven项目. 在导入项目的时候查看端口占用情况:
lsof -i -P
idea 2217 zhengqh 29u IPv4 0x6c3991e519c2f3b1 0t0 TCP localhost:6942 (LISTEN)
idea 2217 zhengqh 55u IPv4 0x6c3991e5197c6551 0t0 TCP localhost:51647->localhost:32252 (SYN_SENT)
idea 2217 zhengqh 315u IPv4 0x6c3991e519c38a31 0t0 TCP localhost:63342 (LISTEN)
idea 2217 zhengqh 338u IPv4 0x6c3991e51980d6f1 0t0 TCP *:51632 (LISTEN)
java 2266 zhengqh 35u IPv6 0x6c3991e513c8cbe1 0t0 TCP *:32252 (LISTEN)
java 2266 zhengqh 69u IPv6 0x6c3991e513c8c6e1 0t0 TCP *:51640 (LISTEN)
GOD! 用的竟然是IPV6. Fuck!
经过漫长的looking for available profiles窗口消失后, 日志打印异常, 这时候再看下端口:
idea 2217 zhengqh 29u IPv4 0x6c3991e519c2f3b1 0t0 TCP localhost:6942 (LISTEN)
idea 2217 zhengqh 315u IPv4 0x6c3991e519c38a31 0t0 TCP localhost:63342 (LISTEN)
idea 2217 zhengqh 338u IPv4 0x6c3991e51980d6f1 0t0 TCP *:51632 (LISTEN)
添加java的java.net.preferIPv4Stack
看起来跟下面的描述是一样的:
I found from looking at lsof -i -P that the maven remote server was attempting to run on IPv6, and apparently IntelliJ could not speak to it on IPv6. I'm not sure if it used to run on IPv4 and something caused it to start using IPv6, or if it always used IPv6 and a mac update somehow made it stop working.
Anyway, the solution I used was to edit /Applications/IntelliJ IDEA 11.app/Contents/Info.plist and add the java.net.preferIPv4Stack parameter to the java process:
<key>java</key>
<dict>
<key>Properties</key>
<dict>
<key>java.net.preferIPv4Stack</key>
<string>true</string>
</dict>
</dict>
在一些文章中说Mac下的IDEA不支持1.7以上版本. 但是看idea.log中日志是1.8的. 尽管修改了idea.properties的JVMVersion=1.7还是没作用.
真正起作用的配置文件应该是/Applications/IntelliJ IDEA 14 CE.app/Contents/Info.plist.
我们之前在idea.vmoptions中修改了并没有起作用(重命名为idea64.options也不行). 但是还是不行啊! 修改了JAVA_HOME下的Info.plist也不行.
同时修改JDK的版本为1.7, 这样启动的时候, 就不会使用1.8了. 如果没有更改,尽管JAVA_HOME是1.7.启动时还是1.8

在IDEA的Maven VM Option中添加: -Djava.net.preferIPv4Stack=true -Didea.maven3.use.compat.resolver
查看idea.log启动的Maven参数(导入Maven工程的时候会启动MavenServer),其中添加上了-Djava.net.preferIPv4Stack=true

如果没有出现漫长的looking for available profiles``, 而是出现Select Maven Projects to import`, 说明可以正常使用了.
那么最终是怎么解决的呢?
注释掉/etc/hosts的::1
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
尝试了哪些操作
1.卸载IDEA,并重装,不行!
2.给IDEA_HOME/bin/idea.vmoptions添加-Djava.net.preferIPv4Stack=true,不行!
3.给IDEA_HOME/Info.plist添加配置项-Djava.net.preferIPv4Stack=true,不行!
4.给IDEA的MAVEN.import vm options添加-Djava.net.preferIPv4Stack=true -Didea.maven3.use.compat.resolver,不行!
5.给JAVA_HOME/Info.plist添加配置项-Djava.net.preferIPv4Stack=true,不行!
6.关闭Mac的IPv6,不行!
7.去掉/etc/hosts的::1,成功!
终于,可以愉快地编码了.
Mac下查看进程对应的端口
IDEA导入Maven项目的时候会启动一个Maven进程, 并且在上面的日志中也报错:java.rmi.RemoteException: Cannot start maven service
下面的两个进程第一个是scala的编译插件:
➜ ~ jps -lm

在上面的SO帖子中, 提到了根据Maven进程查看对应的端口:
我们在线上的Linux机器上实验了Spark的Master进程. 它对应的端口号就是7077. 一共有14个executor子进程.
