Brew安装Maven及其IDEA配置
安装Maven
brew提供了便捷的maven安装⽅式，并且⽬前在m1芯⽚的mac上，brew也会⾃动帮我们装上arm版本的软件（如果已经更新）。
% brew search maven
#使⽤搜索⼯具去搜索maven包
% brew info maven
#使⽤info查看maven包当前的信息情况，包括版本依赖描述等

安装过程很顺利，这时候brew就已经帮我们做好了环境变量了。很多教程在这⼀步后会⼿动去⽣命maven的⽬录情况，我看了⼏个教程⾥⾯的设置完全没有道理，根本链接的不
是brew的安装位置。
% which mvn
# brew已经帮我们做过链接了，可以直接使⽤mvn命令
% mvn -vresizeable的参数设置为true
# 查看安装好的maven信息

配置Maven
可以看到brew⾃动帮我装好了arm版本的maven，因为我是m1芯⽚。如果是x86的芯⽚，会帮你装x86版本，路径位置可能不同，但设置没啥区别，注意换成⾃⼰路径即可。我们
接下来看maven的配置⽂件位置。
上⾯maven信息输出中有Maven home: /opt/homebrew/Cellar/maven/3.8.4/libexec，冒号后⾯就是brew帮我们下载的安装⽬录。直接执⾏cd
/opt/homebrew/Cellar/maven/3.8.4/libexec，进⼊⽬录。
% cd /opt/homebrew/Cellar/maven/3.8.4/libexec
% ls
logging l
# 看到了熟悉的setting⽂件
在xml⽂件中，我们要关注两个地⽅，我在下⾯列了出来localRepository和mirrors。第⼀个localRepository是你本地仓库所在的位置，你的包都会下载到这⾥，默认在你⽤户⽬录
的.m2⽬录下，我觉得挺直观的，就没修改了，这⾥可以换成你想存放的地址。第⼆个mirror是你的包下载地址，因为有墙，所以建议增加阿⾥云仓库配置，来加速下载。具体配
置如下，可以⾃⼰在xml中寻。
<!-- localRepository
| The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
java环境变量配置检测<mirrors>
<!-- mirror
| Specifies a repository mirror site to use instead of a given repository. The repository that
| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
|
<mirror>
<id>mirrorId</id>
<mirrorOf>repositoryId</mirrorOf>
<name>Human Readable Name for this Mirror.</name>
<url>my.repository/repo/path</url>
</mirror>
-->
<mirror>
<id>aliyunmaven</id>
<mirrorOf>*</mirrorOf>
<name>阿⾥云公共仓库</name>
<url>maven.aliyun/repository/public</url>
</mirror>
<mirror>
<id>maven-default-http-blocker</id>
<mirrorOf>external:http:*</mirrorOf>
<name>Pseudo repository to mirror external repositories initially using HTTP.</name>
<url>0.0.0.0/</url>
flash get是什么<blocked>true</blocked>
unix是不是网络操作系统</mirror>
</mirrors>
到这⾥，我们的maven已经安装完毕。仓库位置在我们本地⽤户⽬录下的.m2中，maven安装位置为之前的maven home。我们开始为IDEA配置本地maven环境。
IDEA的Maven配置
我们打开idea的偏好设置，搜索maven，出现以下的配置界⾯。
我们将安装⽬录和配置⽬录替换成配置maven时确定的路径，不好通过访达选⽂件就直接把路径复制填上去，应⽤保存即可。到这⾥就⼤功告成了！
