Root Cause

Jenkins pipeline script has a syntax error, typically a missing closing brace or incorrect nesting of stages/steps, causing the Groovy parser to fail before execution.

中文

Jenkins 管道脚本存在语法错误，通常是缺少闭合大括号或 stages/steps 嵌套不正确，导致 Groovy 解析器在执行前失败。

Workarounds

  1. 90% success Use the Jenkins Pipeline Syntax Validator (http://your-jenkins/pipeline-syntax/) to parse the script and get precise error location. Fix the missing brace at line 12 by adding '}' before 'steps'.

中文步骤

  1. 使用 Jenkins 管道语法验证器（http://your-jenkins/pipeline-syntax/）解析脚本并获取精确错误位置。在第 12 行的 'steps' 前添加缺失的 '}'。
  2. 在提交前本地运行 `groovy -c yourPipeline.groovy` 检查语法；这可以及早捕获错误。
  3. 简化管道以隔离错误：注释掉部分代码直到错误消失，然后修复有问题的块。

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Adding random indentation changes without fixing the actual brace mismatch; Groovy is whitespace-insensitive, so indentation doesn't affect syntax.

  2. 90% fail

    Removing the 'steps' block entirely; this removes the functionality and the pipeline won't execute the intended actions.

  3. 70% fail

    Copying a script from a different pipeline without adjusting the structure; the syntax may be valid but the logic breaks the pipeline.
