export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-17.0.17.0.10-1.el8.x86_64
export PATH=$JAVA_HOME/bin:$PATH

# 安装 Maven（如果没有安装）
sudo yum install maven -y
mvn -version

# 配置阿里云 Maven 镜像
# 将 settings.xml 放到项目根目录
# Maven 会使用阿里云镜像加速依赖下载

# 进入项目目录，编译项目
cd bank-transfer-java
mvn clean package -DskipTests

# 可选：上传 SonarQube 分析
mvn sonar:sonar \
