[英]Jenkins groovy regex match string : Error: java.io.NotSerializableException: java.util.regex.Matcher
I'm trying to get the matched string from a regex in groovy. The matched string prints to the console without problems, but when I try use the matched string in a git command I get the following error:我正在尝试从 groovy 中的正则表达式中获取匹配的字符串。匹配的字符串可以毫无问题地打印到控制台,但是当我尝试在 git 命令中使用匹配的字符串时,出现以下错误:
Err: Incremental Build failed with Error: java.io.NotSerializableException: java.util.regex.Matcher
Here is the code:这是代码:
def binaryName = "298_application_V2_00_Build_07.hex"
def matches = (binaryName =~ /(V)(\d+)(_)(\d+)(_)(Build)(_)(\d+)/)
versionTag = ""+matches[0].getAt(0)
echo "${matches}"
echo "$versionTag"
bat("git tag $versionTag")
bat("git push origin --tags")
How can I get the matched string from the regex?如何从正则表达式中获取匹配的字符串?
This problem is caused by Jenkins' CPS , which serializes all pipeline executions to store as resumable state. 此问题是由Jenkins的CPS引起的,该CPS将所有管道执行序列化以存储为可恢复状态。
Calls to non-serializable methods have to be wrapped in a method annotated with @NonCPS
: 对非序列化方法的调用必须包含在使用
@NonCPS
注释的方法中:
@NonCPS
String getVersion(String binaryName) {
def matches = (binaryName =~ /(V)(\d+)(_)(\d+)(_)(Build)(_)(\d+)/)
versionTag = ""+matches[0].getAt(0)
versionTag
}
this method can now be called from your pipeline. 现在可以从管道中调用此方法。 In case your Jenkins master restarts during execution of this method, it would just run through it completely - which is in many cases, such as yours, absolutely no problem.
如果您的Jenkins主机在执行此方法期间重新启动,它将完全贯穿它 - 这在很多情况下,例如您的,绝对没有问题。
The NonCPS annotation did not have any effect in my declarative pipeline library. NonCPS 注释对我的声明性管道库没有任何影响。 A workaround is to avoid ever returning a matcher as shown in this example:
解决方法是避免返回匹配器,如本例所示:
version = ("release/1.0.0" =~ /(?:release|hotfix)\/(.*)/)[0][1]
