【Maven】VSCode Java+Maven 环境配置

0x00 前言

没写过 Java，得配个带 Maven 的编码环境，不太明白，试试看顺便记录一下

0x01 配置过程

安装 jdk1.8 后，找到安装位置：

(base) dian@CD-Ali doraemon % /usr/libexec/java_home -V
Matching Java Virtual Machines (2):1.8.381.09 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home1.8.0_291 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home

在 .zshrc 配置环境：

# java env
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_291.jdk/Contents/Home 
PATH=$JAVA_HOME/bin:$PATH:.
CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
export JAVA_HOME
export PATH
export CLASSPATH

下载 Maven：

在 Index of /dist/maven/maven-3 里找到所需的 Maven 下载使用，

由于 jdk 版本常年是 1.8.0，这里选择了 3.6.0 的较老对应版本下载：

download: apache-maven-3.6.0-bin.zip
file: 📎apache-maven-3.6.0-bin.zip

解压在自己好找的路径里，比如我放在了 home 目录下，

在公司工作的话，也需要顺便把手手相传的用户自定义设置文件，放在这个目录里：

(base) dian@CD-Ali apache-maven-3.6.0 % pwd
/Users/dian/apache-maven-3.6.0

0x02 VSCode 中 Maven for Java 配置

在 VSCode 的扩展商店里安装 Maven for Java，打开“扩展设置”

在扩展设置的 Path 里填入 maven 路径和 settings file 路径，将使用 JAVA_HOME 的勾打上：

上述在扩展设置中的三步，也等效于直接在 VSCode 的 settings.json 中加入这三行：

之后，在 git 项目下（此处为 gul/doraemon）找到 pom.xml，右键该文件调出菜单栏

菜单栏里会有一个 “显示 Effective POM”，点击后将开始自动下载构建，

经过长长的 Downloading / Downloaded 列表之后，最终出现 BUILD SUCCESS，即环境搭建完成。
