Jenkins claims that "This execution happens in the agent JVM", but when I use this script on script console, I see the next result:

def proc = 'java -version'.execute()
def sout = new StringBuilder(), serr = new StringBuilder()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(10000)
println "out> $sout"
println "err> $serr"

java version "1.7.0"

Then I connect to the same agent via putty, use java -version on conlose and get openjdk version "1.8.0_272"

Why?

Jenkins is using its own version of the JVM, not the one found on the path as specified by your shell's environment variable. – Andy Turner Apr 23 '21 at 08:22
So what versions it uses when it executes a pipeline script? – RedMurloc Apr 23 '21 at 08:28

Not an exact duplicate, but can probably help: https://stackoverflow.com/q/5103121/2422776 – Mureinik Apr 23 '21 at 08:33
