我正在研究一个jenkins文件,我在第三阶段得到了例外:

我一直在阅读它,我知道我无法创建不可序列化的变量。所以,我认为必须使用我的代码的这一部分:
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,如何定义这两个变量以避免该异常?
答案 0 :(得分:3)
你的问题就在这一行:
def has_snapshot = artifact_name =~ /-TEST\.jar/
=~
是Groovy find operator。它返回java.util.regex.Matcher
个实例,该实例不是Serializable
。如果Jenkins在将结果存储到由Jenkins序列化的本地变量(即获得异常时)后决定暂停脚本。这可以通过在调用后立即添加sleep(1)
步骤来轻松测试,并观察引发相同的异常。
要解决此问题,您应该:
java.util.regex.Matcher
结果存储在CPS转换代码中@NonCPS
带注释的方法或使用match operator (==~
) which returns a boolean
(如果它符合您的使用案例)
