Java 使用Gitlab ci multi runner时未找到Maven

我一直在尝试设置GitLab CI，以在Raspbian中构建Maven Java项目，但每当它尝试运行构建脚本时，都会失败，因为它找不到Maven。我使用向导来安装转轮

生成跟踪：

.gitlab-ci.yml

image: maven:3-jdk-8

build:
  script: "mvn clean package"
  artifacts:
    name: "TestProject"
    paths:
    - "target/*.jar"

有人知道这是什么原因吗

编辑：修改/etc/default，将$MAVEN_HOME/bin添加到$PATH中，成功了。

尝试将MAVEN_HOME路径添加到config.toml环境字段中

environment = ["MAVEN_HOME=/path/to/maven"]
