I tried the experimental: Building custom sysimage  
First I create a directory, with an empty .jl-file.  
Then run: “Tasks: run build Tasks” and see this:

For a few moments everythig seems to be OK.  
No, errors, no warnings, no problems…but it runs “endless” (I break it after 30minutes)

My error ?

btw.  
Julia 1.7.3

Problem solved.  
I forgot to actviate an environment and generate a project in the  
directory (I feel a little stupid).  
But now the sysimage are generated correct, 😀
