Jenkins 管道脚本因“类生成期间的一般错误:方法代码太大！"而失败 [英] Jenkins pipeline script fails with "General error during class generation: Method code too large!"

问题描述

运行大型 Jenkins 流水线脚本时，会报错:

When running a large Jenkins pipeline script, it can give the error:

org.codehaus.groovy.control.MultipleCompilationErrorsException:启动失败:类生成期间的一般错误:方法代码太大！

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: General error during class generation: Method code too large!

java.lang.RuntimeException: 方法代码太大！

java.lang.RuntimeException: Method code too large!

此错误的原因是什么?如何解决?

What is the reason for this error and how can it be fixed?

推荐答案

这是由于 Java 和 Groovy 之间的限制，要求方法字节码不大于 64kb.这不是因为 Jenkins Pipeline DSL.

This is due to a limit between Java and Groovy, requiring that method bytecode be no larger than 64kb. It is not due to the Jenkins Pipeline DSL.

要解决这个问题，不要使用单一的整体管道脚本，而是将其分解为方法并调用这些方法.

To solve this, instead of using a single monolithic pipeline script, break it up into methods and call the methods.

例如，而不是:

stage foo
parallel([
 ... giant list of maps ...
])

改为:

stage foo
def build_foo() {
  parallel([
     ...giant list of maps...
  ])}
build_foo()
