Jenkinsfile使用stash

stash：保存临时文件
将文件保存起来，以便同一次构建的其他步骤或阶段使用。 如果整个流水线在同一台机器上执行，那stash是多余的，一般用于跨Jenkins node使用。 stash步骤会将文件存储在tar文件中，对于大文件的stash操作会消耗Jenkins master的计算资源。

name：字符串类型，保存文件的集合的唯一标识
allowEmpty：布尔类型，允许stash内容为空
excludes：字符串类型，排除文件，如果排除多个使用「逗号」分隔
includes：字符串类型，stash文件，留空表示全部
useDefaultExcludes：布尔类型，true：使用Ant风格路径默认排除文件 Ant风格 匹配任何单字符匹配项目根路径下所有在project路径下的.a文件最长匹配原则： /project/dir/file.jsp，现在存在两个路径匹配模式 /**/*.jsp和/project/dir/*.jsp 那么会根据模式/project/dir/*.jsp来匹配
unstash：取出之前stash的文件

pipeline {
   agent none
   stages {
       stage('stash') {
           agent {label "master"}
           steps {
               writeFile file: "a.txt",text: "
               stash(name: "abc", includes: "a.txt")
           }
       }
       stage('unstash') {
           agent {label "node2"}
           steps {
               script {
                   unstash("abc")
                   def content = readFile("a.txt")
                   echo "${content}"
               }
           }
       }
   }
}
