在使用brew或手动安装maven后，使用macOS Catalina并使用终端或iTerm来操作maven，您将需要授予应用程序访问权限以访问用户文件。

系统首选项->隐私(按钮)->全磁盘访问

然后将terminal或iTerm添加到该列表中。

你还需要重新启动你的应用程序，例如终端或iTerm，在给他们完全的磁盘访问权限后。

如果在OS X 10.9 Mavericks上使用MacPorts，你可以简单地做:

sudo port install maven3
sudo port select --set maven maven3

或者，我建议为这些实用程序安装Homebrew。

然后使用以下命令安装Maven:

brew install maven

PS:如果你得到一个404错误，尝试做一个酿造更新之前

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

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.

打开TERMINAL窗口并检查是否已经安装了它。

类型:

$ mvn –version

你应该看到:

Apache Maven 3.0.2 (r1056850; 2011-01-09 01:58:10+0100)
Java version: 1.6.0_24, vendor: Apple Inc.
