Boot error on Windows "Couldn't delete target"

Question

Well, basically I'm facing a problem just on Windows, when I run "boot run dev" on macOS or Linux, it works perfectly, but on Windows, the dream is over, the boot starts but get an error soon as it starts, this is my build.boot:

(set-env!
  :source-paths #{"src"}
  :resource-paths #{"src" "resources"}
  :dependencies '[[org.clojure/clojure "1.9.0" :scope "provided"]
                  [adzerk/boot-cljs "2.1.4" :scope "test"]
                  [adzerk/boot-reload "0.5.2" :scope "test"]
                  [pandeiro/boot-http "0.8.3" :scope "test"]
                  [nightlight "RELEASE"]
                  [org.clojure/clojurescript "1.9.946"]
                  [rum "0.10.8"]
                  [org.roman01la/cljss "1.5.13"]
                  [org.clojure/core.async "0.4.474"]
                  [io.replikativ/konserve "0.4.11"]
                  [ring/ring-core "1.6.3"]
                  [bidi "2.1.2"]
                  [congomongo "0.5.0"]
                  [cljs-http "0.1.44"]
                  [http-kit "2.2.0"]
                  [com.hypirion/clj-xchart "0.2.0"]])

(require
  '[adzerk.boot-cljs :refer [cljs]]
  '[adzerk.boot-reload :refer [reload]]
  '[pandeiro.boot-http :refer [serve]]
  '[nightlight.boot :refer [nightlight sandbox]])

(task-options!    
  aot {:namespace   #{'brad.server}}    
  pom {:project     'brad        
       :version     "0.1.0"         
       :description "FIXME: write description"         
       :url         "http://example/FIXME"         
       :scm         {:url "https://github.com/yourname/brad"}         
       :license     {"Eclipse Public License"                       
                     "http://www.eclipse.org/legal/epl-v10.html"}}    
  jar {:main        'brad.server         
       :file        "brad.jar"}
  cljs {:ids #{"brad/admins" "brad/fisicos"}})


(deftask dev []
  (comp
    (watch)
    (reload :asset-path "brad"
            :cljs-asset-path ".")
    (sandbox :file "java.policy")
    (cljs :source-map true 
          :optimizations :none)
    (target)))

(deftask run []
  (comp
    (serve :dir "target/brad" :port 3000)
    (dev)
    (nightlight :port 4000 :url "http://localhost:3000")))

(deftask build []  
  (comp    
    (cljs :optimizations :advanced          
          :compiler-options {:fn-invoke-direct true})    
    (aot)    
    (pom)    
    (uber)    
    (jar)    
    (target)))

Sorry about the extensive code, I think that maybe the problem is with some permission that I didn't give, I was trying to run boot on git bash, then I tried on windows powershell, the same error was ocurred, please, help me, and I'm sorry about my english.
