tirkarthi commented 6 years ago

Are you using JDK 9? It's an error specific to JDK 9 as I can see from the stacktrace. It should work on JDK8. Can you add the info regarding java -version ?

tirkarthi commented 6 years ago

You can try adding the jvm opts to resolve this in JDK 9 if you cannot switch to JDK 8. Refer : https://github.com/http-kit/http-kit/issues/356#issuecomment-340307541 and https://www.deps.co/blog/how-to-upgrade-clojure-projects-to-use-java-9/

colonelrascals commented 6 years ago

@tirkarthi 

 java -version
java version "10" 2018-03-20
Java(TM) SE Runtime Environment 18.3 (build 10+46)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+46, mixed mode)
tirkarthi commented 6 years ago

Thanks. You can try switching to JDK 8 for now or add the jvm-opts as mentioned. I am still not sure about the dependency that causes this error.

nouse commented 6 years ago

I can fix this problem with adding environment variable, BOOT_JVM_OPTIONS="--add-modules=java.xml.bind" but adding that to .boot/boot.properties doesn't work

kuwze commented 6 years ago

I fixed this by adding [org.clojure/clojurescript "1.10.238"] before [adzerk/boot-cljs "2.1.4"].

So I went from:

(set-env!
 :source-paths #{"src/cljs"}
 :resource-paths #{"html"}

 :dependencies '[[adzerk/boot-cljs "2.1.4"]])

(require '[adzerk.boot-cljs :refer [cljs]])

to:

(set-env!
 :source-paths #{"src/cljs"}
 :resource-paths #{"html"}

 :dependencies '[[org.clojure/clojurescript "1.10.238"]
                    [adzerk/boot-cljs "2.1.4"]])

(require '[adzerk.boot-cljs :refer [cljs]])

I also tried your suggestion nouse and couldn't fix it by adding that line to boot.properties.

gunar commented 6 years ago

Whoah, nice. Still had to do this but now it's working.

phi1ipp commented 5 years ago

Just to confirm that the suggested solution to change dependencies to 

 :dependencies '[[org.clojure/clojurescript "1.10.238"]
                    [adzerk/boot-cljs "2.1.4"]])

works for java 11 as well

z3t0 commented 5 years ago

Just for clarification, is the solution to use a newer version of cljs?

colonelrascals commented 5 years ago

looks like it

gloorfindel commented 4 years ago

To fix (this and future tutorial issues) I updated dependencies to include http-kit, cider/piggieback,nrepl and other dependency versions.

  :dependencies '[[http-kit "2.3.0"]
  [org.clojure/clojure "1.10.0"]
  [org.clojure/clojurescript "1.10.238"]
  [adzerk/boot-cljs "2.1.5"]
  [pandeiro/boot-http "0.8.3"]
  [org.clojure/tools.nrepl "0.2.12"] ;;required in order to make boot-http works
  [adzerk/boot-reload "0.6.0"]
  [adzerk/boot-cljs-repl "0.4.0"]
  [com.cemerick/piggieback "0.2.2"]
  [weasel "0.7.0"]
  [cider/piggieback "0.3.9" :scope "test"]
  [nrepl "0.4.5" :scope "test"]])

Also note one needs to update boot.properties like below:

#Wed Feb 22 16:15:15 CET 2017
BOOT_CLOJURE_NAME=org.clojure/clojure
BOOT_CLOJURE_VERSION=1.10.0
BOOT_VERSION=2.8.2
