Clojurians Log v2

War is created by lein-immutant

https://github.com/juxt/joplin/blob/v0.2.5/joplin.core/src/joplin/core.clj#L83 (classpath/classpath-jarfiles) returns empty collection so this code can't find any migrations have anybody managed to make this function work under wildfly?

Implementation of classpath-jarfiles https://github.com/clojure/java.classpath/blob/master/src/main/clojure/clojure/java/classpath.clj#L87

@edvorg: can you get the output of (clojure.java.classpath/classpath)?

Hello @tcrawley . I'm sorry for the delay. This function gives me only some system-wide and wildfly jars

we had http://dev.clojure.org/jira/browse/CLASSPATH-5 added to address this specifically, but it may be the case that we didn't ever implement the URLClasspath protocol in Immutant

checking on that now

@edvorg: what version of Immutant are you using?

we extend the URLClassloader protocol in 2.1.0 and newer

2.1.0

@edvorg: I can recreate it here. I'll need to do some digging

Any help is needed from my side? I can try to create a minimal project demonstrating an issue..

no, but thanks! I have a minimal project already

ah, nice, thanks

@edvorg: I have a workaround for you, but first, some background why this is happening

inside WildFly, the jars inside the war are never extracted to disk, so they aren't Files, which is why they aren't visible to java.classpath

we can make them files, though, by deploying the war file exploded

to do that, you would create a foo.war/ dir in $WILDFLY_HOME/standalone/deployments/

then unzip foo.war inside the foo.war/ directory

then touch $WILDFLY_HOME/standalone/deployments/foo.war.dodeploy

that will cause the jars in the war to be treated as files

but, there is a bug in Immutant that prevents them from being visible

so you have to patch a function inside immutant, like so:

(defn -main [& args]
  (alter-var-root #'immutant.wildfly/vfs->file
    (constantly
      (fn [url]
        (if-let [match (and url (re-find #"^vfs(:.*)/?" (.toExternalForm url)))]
          (URL. (str "file" (last match)))
          url))))
  (pp/pprint (cp/classpath)))

alternatively, if there is a way to give joplin a list of the migrations, you could io/resource each one to create a list of resource urls

@tcrawley: Thank you very much for your rapid help! We will try that soon

@tcrawley: Thank you once more, it helped
