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.

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
/Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3/bin
➜  bin ll

对于那些想在Mavericks中使用maven2的人，输入:

酿造点击自制/版本

酿造安装maven2

如果您已经安装了maven3，请先在/usr/local/bin中备份3个链接(mvn, m2.conf, mvnDebug):

mkdir贝克

混合

然后重新安装:

Brew卸载maven2(仅当冲突时)

酿造安装maven2

当我最近升级到OS X Mavericks时，我的maven构建开始失败。所以我需要再次安装maven，因为它不是内置的。然后我试着输入命令:

brew install maven 

它可以工作，但它安装了maven的3.1.1版本，这对一些用户(https://cwiki.apache.org/confluence/display/MAVEN/AetherClassNotFound)造成了一些问题。因此，如果遇到同样的问题，您可能希望安装较早的Maven版本3.0.5。要在Homebrew中做到这一点，你必须执行以下命令:

brew install https://raw.github.com/Homebrew/homebrew-versions/master/maven30.rb

就是这样，它将使用不同的Homebrew公式，这将为您提供maven 3.0.5。

这招对我很管用:

$ vim .bash_profile

出口JAVA_HOME = $ (/ usr / libexec / JAVA_HOME)

$ source .bash_profile

在Mavericks(10.9)之前的OS X实际上内置了Maven 3。

如果你使用的是OS X Lion系统，默认情况下你不会安装java。单独运行java，它会提示你安装它。

假设条件满足，运行mvn -version并看到如下输出:

Apache Maven 3.0.3 (r1075438; 2011-02-28 12:31:09-0500)
