Jenkins中聲明式流水線與腳本式流水線的主要區(qū)別在於語法、結(jié)構(gòu)和易用性。聲明式流水線採用預定義結(jié)構(gòu)，語法清晰，適合團隊協(xié)作且易於維護；而腳本式流水線基於Groovy DSL，靈活性更高但需要編程知識。 1. 聲明式流水線通過pipeline、agent、stages等關(guān)鍵字明確劃分邏輯區(qū)塊，降低出錯概率；2. 腳本式流水線使用node塊編寫，更自由但也更複雜，適合高級用戶；3. 聲明式支持內(nèi)置指令如environment、triggers，集成插件更方便；4. 腳本式在動態(tài)生成階段、複雜邏輯控制方面表現(xiàn)更強；5. 對新手而言，聲明式學習曲線更低，社區(qū)資源更豐富；6. 大多數(shù)插件兼容兩者，遷移也較為可行。因此，日常使用推薦聲明式，需深度定制時可選腳本式。

The main difference between a declarative pipeline and a scripted pipeline in Jenkins comes down to syntax, structure, and ease of use. Declarative pipelines are more modern, structured, and easier for most users to read and maintain. Scripted pipelines, while more flexible, rely on Groovy scripting and can be harder to work with if you're not familiar with the language.

Syntax and Structure: Clear Separation

Declarative pipelines use a predefined structure that makes it easier to define stages, steps, and conditions without needing deep programming knowledge. The syntax is designed specifically for defining CI/CD processes.

Scripted pipelines, on the other hand, are written using Groovy-based DSL (Domain Specific Language). They offer more flexibility but require understanding how to write and manage Groovy scripts.

• Declarative example :

   pipeline {
      agent any
      stages {
          stage('Build') {
              steps {
                  echo 'Building...'
              }
          }
      }
  }

• Scripted example :

   node {
      stage('Build') {
          echo 'Building...'
      }
  }

You'll notice the declarative version has a stricter layout, which helps reduce errors and makes scanning the logic easier.

Readability and Maintenance: Easier for Teams

Declarative pipelines tend to be more readable because they follow a consistent format. This makes them better suited for teams or environments where multiple people may need to understand or modify the pipeline over time.

Scripted pipelines can become complex quickly. While this gives experienced users more control, it also means small changes can introduce bugs or make the script hard to debug.

Some things that help with readability in declarative:

• Clearly defined sections like pipeline , agent , stages , and steps
• Built-in directives like environment , triggers , and options
• Easier integration with plugins through standardized syntax

In contrast, scripted pipelines often mix logic and flow control directly into the code, which can make them feel more like general-purpose scripts than configuration files.

Flexibility and Control: When You Need More Power

If you're dealing with advanced use cases—like dynamically generating stages, conditionally skipping large chunks of logic, or integrating deeply with external systems—you might find yourself leaning toward scripted pipelines.

That said, declarative pipelines have improved a lot in recent years. Many advanced features are now available through the script block, allowing you to run arbitrary Groovy code when needed.

Here are some situations where flexibility matters:

• Dynamic decision-making based on build parameters
• Complex error handling or retry logic
• Custom extensions or shared libraries

So while scripted pipelines still offer more raw power, declarative ones are catching up and are usually good enough for most use cases.

Learning Curve and Community Support

If you're new to Jenkins pipelines, starting with declarative is usually a better idea. There's more documentation, tutorials, and community support around declarative syntax.

Scripted pipelines are older and were the default before declarative became stable. As a result, you'll still see many legacy examples online. But unless you have a specific reason to use scripted, declarative is the recommended path.

Just keep in mind:

• Most plugins now support both types
• Migrating from scripted to declarative is possible in many cases
• It's worth learning both eventually, especially if you want deeper control

So depending on your needs—whether simplicity and clarity or full scripting freedom—you can choose the one that fits best. Declarative pipelines are generally easier to work with day-to-day, while scripted ones give you more under-the-hood control.基本上就這些。
