jenkins pipeline将通过执行的shell命令更改环境变量environment

1、可以通过jenkins的sh专门的命令，将shell输出的值赋值给变量

pipeline代码
environment {
    HTTPD_LOCATION = ""
}

HTTPD_LOCATION= sh(  returnStdout: true, script: 'git log --oneline -1 | awk \'{print \$1}\'')
echo "HTTPD_LOCATION =${HTTPD_LOCATION}"


pipe运行结果：
[Pipeline] { (hide)
[Pipeline] sh
+ git log --oneline -1
+ awk '{print $1}'
[Pipeline] echo
HTTPD_LOCATION =0be9fb3
