Why does somestring.digest('SHA-1') fail in pipeline

[ZillaYT]

I have this simple code and it works on my Macs groovy

String sigStr = 'iurpeirupru04790734'
sigStr = sigStr.digest('SHA-1')
println sigStr

But I get this error when I run it in a Jenkins pipeline. Why? Thanks!

Pipeline is a subset of groovy, so something may not work in pipeline that work in groovy standalone. It also may depend on what version of groovy pipeline is using as the digest method was added in groovy 2.5.0 I believe. I don't know what version pipeline is using right now.

Try

sigStr = sigStr.decodeBase64()

which is available since Groovy 1.0 [1]

digest() is available since 2.5.0 [2].

Different Groovy version?

We're on 2.4.x.

And as usual, don't (ab)use pipeline as a general purpose programming environment. It's not intended to be, never was.

Jenkins pipeline has been working for us so far, except for these little gotchas.

Thanks!
