我有以下测试代码来尝试打开和修改文件的内容：

private def updateTagInfoInFile(final String file) {
  final String tmpFile = "tmp.txt"
  sh "ls -al /data/workspace/Utilities/Playground"
  sh "whoami; pwd; ls -al"
  new File("/data/workspace/Utilities/Playground/copy-artifact/$file").eachLine{line->
    if (line.startsWith("Tag")) {
      // Count the number of spaces between "Tag:     <tag>" to preserve the formatting
      final Integer numSpaces = line.length() - line.replaceAll(" ", "").length()
      line = "Tag:"+" ".multiply(numSpaces)+"newTag"
    }
    sh "echo $line >> $tmpFile"
  }
  sh "mv $tmpFile $file"
}

updateTagInfoInFile("someFile.txt")

但我收到以下错误：

+ ls -al /data/workspace/Utilities/Playground

该文件显然存在，那为什么我会收到错误呢？

我有以下 URL 字符串。

https://my.reportUrl.com/scans#~%2528cicd_scan~%2527800172eb-d004-4237-b8e6-797bde26a1ab%252A2c2025-02-04T20%2525%25252A3a16%2525%25252A3a38.511117722Z%2527%2529

什么是 Groovy 方法来获取

https://my.reportUrl.com/scans#~%2528cicd_scan~%2527800172eb-d004-4237-b8e6-797bde26a1ab%252A2c2025-02-04T20%2525%25252A3a16%2525%25252A3a38

部分？即.URL 中最后一个“ ”之前的部分。我知道我可以string.tokenize(".")，然后只需连接我想要的部分，但一定有更好、更酷的方法吗？

$ terraform -v

我有一个实例化多个EC2实例的模块，并且我在部分中打印出我想要的信息output。

// Create an EC2 instances
module "ec2_node" {
  count                  = var.num_nodes
  source                 = "../modules/ec2_node"
  ami_id                 = var.ami_id
  availability_zone      = var.availability_zone
  ...
}

output "module_ec2_node_ec2_name_0" {
  value = module.ec2_node[0].ec2_tag_name
}

output "module_ec2_node_ec2_id_0" {
  value = module.ec2_node[0].ec2_id
}

output "module_ec2_node_private_ip_0" {
  value = module.ec2_node[0].ec2_priv_ip
}

output "module_ec2_node_ec2_name_1" {
  value = module.ec2_node[1].ec2_tag_name
}
output "module_ec2_node_ec2_id_1" {
  value = module.ec2_node[1].ec2_id
}

output "module_ec2_node_private_ip_1" {
  value = module.ec2_node[1].ec2_priv_ip
}

有没有办法在该部分中放置一个循环，output而不是像我这样？

我使用AWS list-distributions CLI 命令获取系统中的所有 ClodFront。例如

$ aws cloudfront list-distributions
{
    "DistributionList": {
        "Items": [
            {
                "Id": "E2DMQDAA2UTH",
                "ARN": "arn:aws:cloudfront::0123456789:distribution/E2DMQDAA2UTH",
                "Status": "Deployed",
                "LastModifiedTime": "2024-07-08T09:31:24.859000+00:00",
                "DomainName": "abcdefghijk.cloudfront.net",
                "Aliases": {
                    "Quantity": 1,
                    "Items": [
                        "sandbox.images.domain.com"
                    ]
                },
                "Origins": {
                ...
                },
                ...
            },
            {
                // more items
            }
        }
    }
}

使用选项--query获取包含 和 的所有内容的DistributionList.Items.AliasesCLI命令是什么？我尝试了以下 sandboxdomain.com

aws cloudfront list-distributions --query 'DistributionList.Items[?contains(Aliases.Items[*], `sandbox`) && contains(Aliases.Items[*], `domain.com`)].[{Id:Id}]' --output json

但我明白

In function contains(), invalid type for value: None, expected one of: ['array', 'string'], received: "null"

我想要做的事情的正确语法是什么？我知道我可以编写管道/Groovy 脚本来过滤掉一些东西，但我不想这么做。

我有以下测试代码，其中我创建了一个列表Map<String,String>并想要打印列表中每个映射的键/值。

#!/usr/local/bin/groovy

List<Map<String,String>> list = []
Map<String, String> map1 = ["a":"a"]
list.add(map1)
println list
Map<String, String> map2 = ["b":"b"]
list.add(map2)
println list
list.each { m->
  println "${m.key} ${m.value}"
}

执行代码时，我得到

[[a:a]]
[[a:a], [b:b]]
null null
null null

在列表中打印每个地图的键和值的正确方法是什么？

我正在关注这个优秀的Spring Boot 快速入门教程。在进入会话 #29 之前，我一直表现良好，在会话 #29 中，我将服务连接到嵌入式 Apache Derby DB，并实现 GET 和 PUT 命令。我几乎遵循了作者的代码，并有以下内容。

package io.javabrains.springbootstarter.topc;
import jakarta.persistence.Entity;
import jakarta.persistence.Id;

@Entity
public class Topic {
    @Id
    private String id;
    private String name;
    private String desc;

    public Topic(){}
    
    public Topic(String id, String name, String desc) {
        super();
        this.id = id;
        this.name = name;
        this.desc = desc;
    }
    
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getDesc() {
        return desc;
    }
    public void setDesc(String desc) {
        this.desc = desc;
    }
}

        return topics.stream().filter(t -> t.getId().equals(id)).findFirst().get();
    }

    public void addTopic(final Topic topic) {
        // topics.add(topic);
        topicRepository.save(topic);
    }

    public void updateTopic(Topic topic, String id) {
        for (Topic t : topics) {
            if (t.getId().equals(id)) {
                topics.set(topics.indexOf(t), topic);
                break;
            }
        }
    }

    public void deleteTopic(String id) {
        topics.removeIf(t -> t.getId().equals(id));

我有一个设置 NodeJS 版本的函数。

def setNodeVersion(final String nodeVersion="11.15.0") {
  env.NODE_HOME = "${tool 'Node-"${nodeVersion}"'}"
  env.PATH="${env.NODE_HOME}/bin:${env.PATH}"
  sh """
    node -v
    npm -v
  """
}

setNodeVersion("12.22.1")

但是当我调用它时，我得到

ERROR: No tool named Node-"${nodeVersion}" found
Finished: FAILURE

正确的语法是什么？

我按照了解 Groovy 变量及其函数中的示例进行操作，并得到以下内容。EnvironmentMgr是我在其他地方定义的单例类，并且它有效。

@Singleton
class EnvironmentMgr {
  String ecsCluster = "sandbox"
  ...
}

abstract class EcsService {
  def setup() {
    if (envMgr == null) {
      println "envMgr is null"
      envMgr = EnvironmentMgr.instance
    }
  }

  protected static def envMgr = null
}

class Service1 extends EcsService {
  def setup() {
    super.setup()
    // Do something for Service1
  }
}

class Service2 extends EcsService {
  def setup() {
    super.setup()
    // Do something for Service2
  }
}

def svc1 = new Service1()
svc1.setup()
def svc2 = new Service2()
svc2.setup()

我希望printlnin 中的语句EcsService:setup()打印一次，但它打印了两次调用。这是为什么？我怎样才能让它发挥作用？谢谢。

编辑： 上面的代码在我的 Mac 上按预期工作，就像直接的 Groovy 代码一样，但在 Jenkins 管道中运行时，无法识别静态性。
