I stumbled
on
https://stackoverflow.com/questions/55423036/groovy-string-interpolation-when-string-is-defined-before-the-interpolated-varia
and I found this snippet worked just fine after I approved the signature in
jenkins
import groovy.text.SimpleTemplateEngine
node("docker") {
stage("eval") {
def pathname = "/srv/\${host}/foo/bar"
def templateMessage = new
SimpleTemplateEngine().createTemplate(pathname)
def result = { host -> templateMessage.make(host: host)}
def HOST = "myhost"
println(result(HOST))
}
}
