Weird. And sorry for misunderstanding you.

There might be a stacktrace in the Jenkins log file (hopefully). Or you could 
try catch all exceptions in your scripted pipeline to get some more details…

I just tried to reproduce your problem (or the one I now think you are 
describing), but unfortunately it works like a charm 😲

Subject: Re: Shared library function cannot call other shared library function 
in separate file if called function uses "writeFile"

I think you've both misunderstood what I'm saying, or I'm not being clear 
enough.

I'm not writing to write a function named "writeFile", I'm just calling that 
pipeline step from the function.  All of the function names I'm creating are 
definitely unique.  If I call the "vars" function that calls "writeFile", I get 
the seemingly generic error with no other information.  If I instead call the 
inline function with contents identical to the "vars" function, it works fine.

The statement I make in the subject doesn't make sense, but I don't know how 
else to describe it.

I'm working on a set of builds using scripted pipelines.  Our Jenkinsfiles are 
very short, all of the build logic is in the shared library.  In the "main" 
shared library function, I'm trying to call another function defined in another 
"vars" class.  We have many of these already.  In this called function, I have 
a call to the "writeFile" pipeline step to create a temporary file used by a 
shell script called immediately after that.  This is the only place anywhere in 
our builds that we call "writeFile".

When I run the build, I get this very unhelpful message:


Jenkins Job Failed due to Exception : org.codehaus.groovy.control.ErrorCollector

There is literally no other information provided, except for the log lines that 
come before it.  I found that an echo statement that is called before this 
suspect function is called is emitted in the log.  An echo statement as the 
first line of the "call()" method of the function being called is NOT emitted 
in the log. Somehow the act of calling the function makes it die, with no 
explanation.

So, I tried a workaround.  In the calling script file, I added a "def" at the 
end of the file, to define an "inline function" with almost the same name as 
the "vars" function name.  I copied the entire body of the "call()" method of 
the vars function into that inline function.  I replaced the call to the vars 
function with the call to the inline function.  It worked on the first try.

Any ideas what might cause this?
