在jenkins pipline sh step中使用sed转义引号

Question

需要在使用sed的sh步骤中插入变量值，但收到的结果为空，代码如下：

#!/usr/bin/env groovy

def call(def cap_server){
    dir("ruby"){
        cap_server="pidor"
        sh '''bundle install'''
        sh '''sed -i "1i server '${cap_server}', user: 'ubuntu', roles: %w{web app db sidekiq}, ssh_options:{ keys: %w(~/.ssh/id_rsa)}" config/deploy/qa.rb'''
        sh '''bundle exec cap qa deploy'''
    }
}

结果如下：

+ sed -i 1i server '', user: 'ubuntu', roles: %w{web app db sidekiq}, ssh_options:{ keys: %w(~/.ssh/id_rsa)} config/deploy/qa.rb

Answer 1

您需要使用双引号来创建强模板

sh """sed -i "1i server '${cap_server}', user: 'ubuntu', roles: %w{web app db sidekiq}, ssh_options:{ keys: %w(~/.ssh/id_rsa)}" config/deploy/qa.rb"""
