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".

免责声明:这是一个完整的答案，考虑到OS X的最后一个版本(10.9 AKA Mavericks)。我知道我在这个答案中编译的所有内容都已经出现在页面中，但在一个答案中清楚地表达出来会让它更清楚。

首先，对于以前的OS X版本，Maven是默认安装的。如果没有Java，在终端上运行you@host:~ $ Java将提示您安装Java。

在Mac OS X 10.9 (Mavericks)中，Maven不再默认安装。然后可能有不同的选择:

Using Homebrew: you@host:~$ brew install maven will install latest Maven (3.5.2 on 02/01/2018) you@host:~$ brew install maven30 will install Maven 3.0 if needed Using Macports: (I did not test this) you@host:~$ sudo port install maven will install latest Maven (?) or: you@host:~$ sudo port install maven3 will Install Maven 3.0 you@host:~$ sudo port select --set maven maven3 selects that version of Maven Installing by hand: Download Maven from its homepage Follow the installation instructions: Extract the distribution archive, i.e.apache-maven-3.3.9-bin.tar.gz to the directory you wish to install Maven 3.3.9. The subdirectory apache-maven-3.3.9 will be created from the archive. Optional: Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven. Make sure that JAVA_HOME is set to the location of your JDK, e.g. export JAVA_HOME=$(/usr/libexec/java_home -v 1.8) and that $JAVA_HOME/bin is in your PATH environment variable (although that might not be necessary with the latest Mac OS X versions and the Oracle JDK). Add extracted apache-maven-3.3.9/bin to your $PATH Run mvn --version to verify that it is correctly installed.

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

打开终端 只需使用brew命令安装maven

brew install maven

下载安装完成后。检查maven版本

mvn -version

给你!!现在，您已经成功地在mac os上安装了maven。
