BUG with libraryResource : No such library resource null could be found.

[Yannick Lacaute]

Hi,

In a shared library, in a groovy script in /vars, the following code is working perfectly:

String call(String stageName) {
  String cowMsg = libraryResource 'cow.txt'
  if (cowMsg != null) {
    def vars = [:]
    vars['MESSAGE'] = "BEGIN STAGE: ${stageName}"
    def engine = new StreamingTemplateEngine()
    def asciiArtMsg = engine.createTemplate(cowMsg).make(vars).toString()
    echo "${asciiArtMsg}"
} else {

    echo "I never see that because cowMsg is not null..."

}

This prints my file cow.txt as expected, because cowMsg is NOT null.

BUT : if I remove the "if", I have this error :
  No such library resource null could be found.

It is like my resource suddenly became null !

I load some other files without the need of this mysterious "if".

Is that a Groovy bug ?

Any chance this is being called from a @NonCPS method? I've seen similar behaviour in that case.

No, all my functions are directly called from "steps", in a declarative pipeline
