jenkinsfile中的NotSerializableException
我正在处理jenkinsfile,在第三阶段遇到异常:
an exception which occurred:in field com.cloudbees.groovy.cps.impl.BlockScopeEnv.locals

我一直在阅读它,我知道我无法创建不可序列化的变量。因此,我认为这必须与我的代码的这一部分有关:
def artifact_name = sh ( script: "ls -b *.jar | head -1",
returnStdout: true
).trim()
def has_snapshot = artifact_name =~ /-TEST\.jar/
if (has_snapshot) {
//Do something
}
我的问题是,如何定义两个变量以避免该异常?
回答:
您的问题是这一行:
def has_snapshot = artifact_name =~ /-TEST\.jar/
该=~
是Groovy的查找操作。它返回一个java.util.regex.Matcher
实例,不是Serializable
。如果Jenkins在将结果存储在本地变量中后决定将脚本存储在Jenkins序列化的本地变量中,即在您获取异常之后。通过sleep(1)
在调用后立即添加一个步骤,并观察是否引发了相同的异常,可以轻松地测试这一点。
要解决此问题,您应该:
- 不将
java.util.regex.Matcher
结果存储在CPS转换的代码中 - 将用法移动到带
@NonCPS
注释的方法中,或使用匹配运算符(==~
)返回一个boolean
(如果适合您的用例)
