Copy files unsing the MWE2 workflow [message #674296]

hey,

I created a generator project using xpand which works fine.

Now i need to copy some existing files to the ones i generate. So i was looking for a way to just copy files into my src-gen folder.

I'm doing this like that:

component = org.eclipse.emf.mwe.utils.FileCopy {
		sourceFile = "src/models/test.c"
		targetFile = "src-gen/Software/test.c"
	}

as long as the sourceFile is located in the eclipse project path everything works fine, but the files i need to copy are located outside the eclipse project. if i try to access them i get a error because eclipse can't access the path. Think it has to be some mistake i am doing with the source path but i can't find it...

I try it like this

....
 sourceFile = "d:/modules/test.c"
....

I also tryed to google it but i didn't found anything else about how to copy files with a MWE2 workflow, hope you can help me!

Hi,

i cannot reproduce this.

this works for me

module Test

Workflow {
	
	component = org.eclipse.emf.mwe.utils.FileCopy {
		sourceFile = "c:/work/test.c"
		targetFile = "src-gen/Software/test.c"
	}
	
}

can you please post the complete error message from the workflow?

i put the code part you wrote in front of mine and this is working.
and i think i found the problem, if i try to put the targetFile to a folderwhich doesn't exist yet i get a error that the system can't find the path.

so i think i have to create the folders first before i can start putting files in them?

Hi,

yes this is about the target file and not about the source file as you stated in your first post.
the folder you want to copy the files to must exist before you call the FileCopy Component.

hey,

ah ok, i first thought the command generates the missing folders.

is there a command to generate folders using MWE2 workflows?

thanks for your effort!

Hi,

afaik the is not component for that but it should be a 10-liner to create such a component - or you come up with a custom version of the FileCopy component. here is the source.
