generated_files = \     dw.js/dw-2.0.js \     www/static/css/datawrapper.css \     www/static/css/chart.base.css  all: $(generated_files)  clean:     rm -f -- $(generated_files)  dw.js/dw-2.0.js: dw.js/src/*.js     cd dw.js     grunt  assets: www/static/css/datawrapper.css www/static/css/chart.base.css  # www/static/js/dw-2.0.js: dw.js/dw-2.0.js #   @cp dw.js/dw-2.0.js www/static/js/  # www/static/js/dw-2.0.min.js: dw.js/dw-2.0.js #   @php -r "require 'vendor/autoload.php'; file_put_contents('www/static/js/dw-2.0.min.js', \jshrink\minifier::minify(file_get_contents('dw.js/dw-2.0.js')));"  messages:     scripts/update-messages.sh  www/static/css/datawrapper.css: assets/styles/datawrapper/* assets/styles/datawrapper/**/*     node_modules/.bin/lessc assets/styles/datawrapper/main.less > $@  www/static/css/chart.base.css: assets/styles/chart.base/*     node_modules/.bin/lessc assets/styles/chart.base/main.less > $@` 

what happening files you're attempting generate exist. why prevent make command building you're files? it's because of way make interprets makefiles.

let's @ generic makefile rule below , interpret manually.

target: prerequistes     actions 

make target check , compare time-stamp of file target timestamps of prerequisite files. if of prerequisites have more recent time-stamp target (i.e. 1 of prereqs "younger"), actions executed.

so, if prerequisites have been made , have same timestamp has target, make write message make: nothing can done target

so, can 2 things. best thing ensure files you're trying generate not exist. solution run make -b target cause make to make targets

please read question reference
