编辑：最后添加了更多信息。另外，还可以通过jetty-runner.jar（不是tomcat）来进行战争
我正在使用boot作为clojure应用程序的构建工具。
这是我在一个项目中使用cljs，cljc和clj代码（以及sass）编写的第一个应用程序。
我的build.boot具有以下task-options
(def db-opts (:db (clojure.edn/read-string (slurp "resources/config.edn"))))
(task-options!
pom {:project 'gcr
:version "0.1"}
cljs {:optimizations :simple}
uber {:as-jars true}
war {:file "gcr.war"}
ragtime {:database (str "jdbc:"
(:dbtype db-opts) "://"
(:user db-opts) ":"
(:password db-opts) "@"
(:host db-opts) ":"
(:port db-opts) "/"
(:dbname db-opts))}
test {:include #"gcr.test"
:junit-output-to "junit-out"})
我的build任务定义如下：
(deftask build
"Builds an uberjar of this project that can be run with java -jar"
[]
(comp
(aot :all true ;; :namespace #{'gcr.server}
)
(pom)
(cljs :optimizations :simple)
(sass)
(uber)
(jar :file "gcr.jar" :main 'gcr.server)
(sift :include #{#"gcr.jar"})
(target)))
当我运行boot build时，项目会正常运行，没有任何错误。
但是当我运行java -jar target/gcr.jar
我得到以下信息：
$ java -jar target/gcr.jar
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=lcd -Dswing.aatext=true
Exception in thread "main" java.lang.NoClassDefFoundError: clojure/lang/Var

我已经研究了大约24小时，但仍然无法弄清楚如何使其正常工作。 （我终于能够与jetty-runner进行一场战争，但无法在Tomcat上进行战争）
更多信息：
我的boot.properties是
BOOT_CLOJURE_NAME=org.clojure/clojure
BOOT_CLOJURE_VERSION=1.10.0
BOOT_VERSION=2.8.2
我正在使用openjdk version "1.8.0_202"
我检查了构建的jar文件是否使用jar tf target/gcr.jar使用clojure jar，并列出了以下行：
7c506484bc48541ffa5dcb4d9366a8a2-clojure-1.10.0.jar
我的IFDE工作正常，我定义了以下dev任务，如下所示：
(deftask dev
"Launch Immediate Feedback Development Environment"
[]
(comp
(serve :handler 'gcr.core/app ;; ring handler
:resource-root "public" ;; root classpath
:reload true) ;; reload ns
(watch)
(reload)
(cljs-repl) ;; before cljs task
(cljs)
(sass)
(target :dir #{"public"})))
set-env!部分如下：

:resource-paths #{"html" "resources"}

经过大量的任务处理，我能够构建一个与jetty-runner配合使用的war文件，并具有以下任务：
(deftask build-war
"Build the target/app.war file"
[]
(comp
(aot :all true)
(web :serve 'gcr.core/app)
(cljs :optimizations :advanced)
(sass)
(sift :move {#"(.*)js$" "public/$1js"
#"(.*)html$" "public/$1html"
#"css/(.*)" "public/css/$1"})
(uber)
(war :file "gcr.war")
(sift :include [#"gcr.war"])
(target)))
使用sift任务将静态资源移动到public文件夹是关键，因为我在routes.clj中将compojure资源定义如下（不包括API和其他路由） ）。
(defroutes gen-routes
(GET "/login" [] auth/auth-handler)
(files "/" {:root "public"}) ;; to serve static resources
(resources "/" {:root "public"}) ;; to serve anything else
(not-found "404 Page Not Found")) ;; page not found
但是，这仍然不会产生适用于tomcat的war文件。也就是说，在部署到tomcat时，所有API路由均可按预期工作，但是静态html文件显示为HTTP / 404。
