Gabriel Konat added a comment - 2016-10-07 09:39 Same problem here on Jenkins 2.23. Static method is rejected, but does not show up in the 'In-process Script Approval' page. I even manually added 'staticMethod java.lang.Math round java.math.BigDecimal' as an approved signature to the script approval XML file and restarted Jenkins, but the method is still rejected.

Jesse Glick added a comment - 2016-10-07 21:02 “Unclassified method” errors generally indicate a bug in the script-security plugin; there is nothing to approve because it means Jenkins was unable to determine what the script was attempting to call. For diagnosis please supply a complete, minimal script reproducing the error.

Gabriel Konat added a comment - 2016-10-08 08:16 I see. The following pipeline script triggers the exception: echo Math .round(currentBuild.duration / 1000)

Julien Garcia Gonzalez added a comment - 2016-10-17 10:07 Hello, I got the same on echo Math.ceil(10.234)

Alex Gray added a comment - 2017-08-09 18:01 Not sure if this helps people, but as a workaround, you can run your script like so: java -jar jenkins-cli.jar -remoting -noCertificateCheck -i id_rsa -s JENKINS_URL groovy /tmp/my_script.groovy where /tmp/my_script.groovy contains: echo Math .ceil(10.234)

Jesse Glick added a comment - 2017-08-21 14:42 Gabriel Konat & Julien Garcia Gonzalez your cases are likely different from that reported by Roy Tinker . There are a lot of reasons why script-security may fail to identify the Java method which some Groovy expression is intending to call. The original probably involved varargs; these newer ones perhaps involve double vs. float coercions.

Andrew Bayer added a comment - 2018-02-23 18:49 At least as of script-security 1.41, I can't reproduce the original error from new String(java.nio.file.Files.readAllBytes(java.nio.file.Paths.get("/some/path"))) , so I'm closing this. For any other method calls that produce an unclassified staticMethod ... error, please open a new ticket.
