Describe the bug [Required]

My configure as following
latex-workshop.latex.recipes
{ "name": "Knitr", "tools": [ "knitr","latexmk" ] }

and

latex-workshop.latex.tools
`{
"name": "knitr",
"command": "Rscript",
"args": [
"-e",
"knitr::knit('%DOCFILE_EXT%')"
],
"env": {}
}

{
"name": "latexmk",
"command": "latexmk",
"args": [
"-synctex=1",
"-file-line-error",
"-pdf",
"-outdir=%OUTDIR%",
"%DOC%.tex"
],
"env": {}
}`

Manual Recipe -> it works well!! However, I used the option
**"latex-workshop.latex.autoBuild.run":"onFileChange",
"latex-workshop.latex.recipe.default":"lastUsed"
**
then it comes with error "Failed to resolve build recipe: undefined"

Thanks for your report as it makes me realise that I forgot to write the corresponding documentation in the wiki! It seems that your logs are truncated as there is no reference to Failed to resolve build recipe: undefined in them. Could you post the full content?

Currently, autobuild for .rnw files looks for the first recipe whose names (converted to lowercase) contains rnw or rsweave. I can extend the regex to match knitr too. Could you try to rename your recipe and let me knnow? However, with latex-workshop.latex.recipe.default: lastUsed everything should be working fine once you manually build the file once.

I will investigate all this.

• I'm so silly! now this Plugin can work perfectly with .Rnw without any additional configuration. Looks like this happened recently? Thank you for telling the tip. It provides exactly what I need.

• By the way, I could not find the log file because it seems that the compilation process take place forever.

This is now explained in the wiki https://github.com/James-Yu/LaTeX-Workshop/wiki/Compile#building-a-rnw-file

This new mechanism was introduced in 8.9.0. See the discussion in #2013.
