您可以使用自制软件安装maven。命令为 $ brew安装maven

在OS X上安装Maven，请到Apache Maven官网下载二进制压缩文件。

然后，您可以将下载文件夹中的apache-maven-3.0.5文件夹转移到您想要保存Maven的任何地方;然而，由于其余的过程涉及到命令行，我建议你从那里做所有的事情。

在命令行中，你可以运行如下代码:

mv ~/Downloads/apache-maven-3.0.5 ~/Development/

这只是我个人的偏好——在我的主目录中有一个“Development”目录。如果你愿意，你可以选择其他的。

接下来，编辑~/。在您选择的编辑器中配置文件，并添加以下内容:

export M2_HOME="/Users/johndoe/Development/apache-maven-3.0.5"
export PATH=${PATH}:${M2_HOME}/bin

第一行对Maven很重要(必须是一个完整的显式路径);为了运行“mvn”二进制文件，第二行对shell很重要。如果.profile中已经有第二行的变体，那么只需在它的末尾添加${M2_HOME}/bin。

现在打开第二个终端窗口并运行

mvn -version

输出应该是这样的…

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 13:51:28+0000)
Maven home: /Users/johndoe/Development/apache-maven-3.0.5
Java version: 1.7.0_40, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.9", arch: "x86_64", family: "mac"

有几件事需要注意:

If you've installed the Oracle JDK 1.7, then you may find Maven reports JDK 1.6 in the above output. To solve this, add the following to your ~/.profile: export JAVA_HOME=$(/usr/libexec/java_home) As some have pointed out, Maven has historically been supplied either with OS X itself, or with the optional Command Line Tools for XCode. This may cease to be the case for future versions of OS X, and in fact OS X Mavericks does not include Maven. Personal opinion: This could be because they are still in beta, or it could be that Apple have taken a look at the latest Thoughtworks Technology Radar, and spotted that Maven has been moved to "Hold".

安装Maven有两种方法

安装maven之前 检查MVN -version，确保maven没有安装在系统中

方法1:

Brew安装专家

方法2:

访问https://maven.apache.org/download.cgi 选择“二进制链接”中的任意一个 解压缩链接 移动到应用程序文件夹 使用导出更新.bash配置文件 执行MVN -version命令

两个方法

(use homebrew) Auto install: Command: brew install maven Pros and cons Pros: easy Cons: (probably) not latest version Manually install (for latest version): Pros and cons Pros: use your expected any (or latest) version Cons: need self to do it Steps download latest binary (apache-maven-3.6.3-bin.zip) version from Maven offical download uncompress it (apache-maven-3.6.3-bin.zip) and added maven path into environment variable PATH normally is edit and add: export PATH=/path_to_your_maven/apache-maven-3.6.3/bin:$PATH into your startup script( ~/.bashrc or ~/.zshrc etc.)

额外的注意

如何立即生效并检查安装是否正确?

A:

source ~/.bashrc
echo $PATH
which mvn
mvn --version

这里的输出:

➜  bin pwd

➜  bin ll

详情请参考我的(中文)帖子:【已解决】Mac中安装Gradle

您可以使用Maven版本管理器，通过它可以在每个目录基础上使用多个版本的Maven。

安装

使用自制软件安装mvnvm

没有自制的mkdir -p ~/bin && curl -s https://bitbucket.org/mjensen/mvnvm/raw/master/mvn > ~/bin/mvn && chmod 0755 ~/bin/mvn，并添加~/bin到路径。

使用

默认的版本

要设置默认maven版本，请将环境变量DEFAULT_MVN_VERSION设置为默认使用的maven版本。

文件夹的Maven版本

创建名为mvnvm的文件。属性，并按如下方式配置maven版本

mvn_version = < maven版>

brew install maven31 (if you have homebrew)
