【已解决】mac中安装maven

折腾:

【已解决】VSCode调试Java弹框提示:Maven executable not found in PATH Please specifiy maven.executable.path in Settings

期间,突然感觉,或许此处提示,就是因为mac中缺少maven

所以要去mac中安装maven

mac install maven

mac   maven

maven

Maven – Welcome to Apache Maven

Maven Repository: Search/Browse/Explore

Maven – Download Apache Maven

Maven 3.3+ require JDK 1.7 or above to execute – they still allow you to build against 1.3 and other JDK versions by Using Toolchains

apache-maven-3.6.3-bin.zip

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

Maven – Installing Apache Maven

确保mac中已设置好JAVA_HOME

【已解决】maven环境变量设置成M2_HOME还是M3_HOME还是MAVEN_HOME

所以只需要去设置Maven的bin的路径

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

到path中

vi ~/.bashrc

export PATH=/Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3/bin:$PATH

source ~/.bashrc

去确认已安装:

➜  bin which mvn
/Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3/bin/mvn
➜  bin mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3
Java version: 1.8.0_112, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.14.6", arch: "x86_64", family: "mac"

此处,还有点担心,没有设置

/Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3

为maven的home相关的变量呢

发现从maven版本输出信息中有:

Maven home: /Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3

意味着:其maven自己就可以从mvn的bin所在路径

Maven home: /Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3/bin

推断出上一级目录就是maven的home的目录

-》所以最新版maven不需要设置home相关目录,更不需要设置之前的M2_HOME,就是这个意思了。

后来去回答了帖子:

macos – Maven Install on Mac OS X – Stack Overflow

java – How to ensure maven is installed in mac – Stack Overflow

【总结】

mac中安装maven

(1)用brew

brew install maven

但是不一定是最新版。

(2)手动下载和安装最新版

从官网

Maven – Download Apache Maven

下载zip二进制安装包,比如:

apache-maven-3.6.3-bin.zip

放到某个目录:/Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3

解压,其中有bin,lib等子目录,bin下面有mvn二进制可执行文件

把对应目录的bin路径,放到PATH中:

编辑启动脚本

vi ~/.bashrc

再.bashrc的最后加上:

export PATH=/Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3/bin:$PATH

然后wq保存退出。

回到终端,想要立刻生效可以:

source ~/.bashrc

确认是否已正确安装:

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

以及查看版本:

➜  bin mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /Users/crifan/dev/dev_tool/java/maven/apache-maven-3.6.3
Java version: 1.8.0_112, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.14.6", arch: "x86_64", family: "mac"

即可。
