Question

是否可以在一个脚本块中的 IF 内多次重新分配变量值？我有一个脚本块，我需要将变量值传递给不同的环境：

script {
    if (env.DEPLOY_ENV == 'staging') {
        echo 'Run LUX-staging build'
        def ENV_SERVER = ['192.168.141.230']
        def UML_SUFFIX = ['stage-or']
        sh 'ansible-playbook nginx_depl.yml --limit 127.0.0.1'
        
        echo 'Run STAGE ADN deploy'
        def ENV_SERVER = ['192.168.111.30']
        def UML_SUFFIX = ['stage-sg']
        sh 'ansible-playbook nginx_depl.yml --limit 127.0.0.1'                      
        
        echo 'Run STAGE SG deploy'
        def ENV_SERVER = ['stage-sg-pbo-api.example.com']
        def UML_SUFFIX = ['stage-ba']
        sh 'ansible-playbook nginx_depl.yml --limit 127.0.0.1'                                              
    }
}

但是我在 Jenkins 作业中在第二个变量赋值中收到一个错误：

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 80: The current scope already contains a variable of the name ENV_SERVER
@ line 80, column 11.
                    def ENV_SERVER = ['192.168.111.30']
         ^

WorkflowScript: 81: The current scope already contains a variable of the name UML_SUFFIX
 @ line 81, column 11.
                    def UML_SUFFIX = ['stage-sg']
         ^

或者在脚本块的一个 IF 部分内进行多重赋值的任何其他方法。

使用 def 定义变量。这仅在第一次调用时需要。所以删除其他调用的 def 应该可以工作

script {
  if (env.DEPLOY_ENV == 'staging') {
      echo 'Run LUX-staging build'
      def ENV_SERVER = ['192.168.141.230']
      def UML_SUFFIX = ['stage-or']
      sh 'ansible-playbook nginx_depl.yml --limit 127.0.0.1'
      
      echo 'Run STAGE ADN deploy'
      ENV_SERVER = ['192.168.111.30']
      UML_SUFFIX = ['stage-sg']
      sh 'ansible-playbook nginx_depl.yml --limit 127.0.0.1'                      
      
      echo 'Run STAGE SG deploy'
      ENV_SERVER = ['stage-sg-pbo-api.example.com']
      UML_SUFFIX = ['stage-ba']
      sh 'ansible-playbook nginx_depl.yml --limit 127.0.0.1'                                              
  }
}

变量的作用域只限于 if 块，因此您无法在该块之外访问它们。
