我看到您在终端中尝试运行 `java -version`、`javac -version` 和 `mvn -version` 命令都失败了，系统提示无法识别这些命令。让我先检查一下您的环境配置情况，然后帮您解决这个问题。

|

我看到问题了！从环境变量检查结果可以看出：
|
||
|
||
1. **JAVA_HOME** 环境变量没有设置（输出为空）
|
||
2. **MAVEN_HOME** 环境变量没有设置（输出为空）
|
||
3. **PATH** 变量中也没有包含Java和Maven的bin目录
|
||
|
||
这就是为什么系统无法识别 `java`、`javac` 和 `mvn` 命令的原因。让我帮您解决这个问题：

- [ ] 检查系统中是否已安装Maven
|
||
- [ ] 如果Java未安装，指导安装Java
|
||
- [ ] 如果Maven未安装，指导安装Maven
|
||
- [ ] 配置环境变量JAVA_HOME、MAVEN_HOME和PATH
|
||
- [ ] 验证Java和Maven安装是否成功
