Class cast exception running gradle clojureRepl

[.Santanu Chakrabarti]

I am using clojuresque 1.7.0. And I am getting a class cast exception as I run "gradle clojureRepl" from command line.

Stack trace
==========

Exception in thread "main" java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.String
    at clojuresque.tasks.repl$eval905$start_repl_task_driver__907.invoke(repl.clj:11)

    at clojuresque.Driver.main(Driver.java:49)
:clojureRepl FAILED

 

It seems the if statement that checks if the type of port variable is a string is not working.

My gradle.build file
================

buildscript {
    repositories {
        mavenCentral()
        maven { url 'http://clojars.org/repo' }
    }
    dependencies {
        classpath 'clojuresque:clojuresque:1.7.0'
    }
}

apply plugin: 'clojure'

repositories {
    mavenCentral()
    maven { url 'http://clojars.org/repo' }
}

dependencies {
    compile "org.clojure:clojure:1.6.0"
    runtime "org.clojure:tools.nrepl:0.2.10"
}

Work around is to add the following in build.gradle file.

clojureRepl {
    port = "7888"
}

Hi,

Thanks for the workaround. Now it doesn't fail but I can't see the console prompt either. Repl starts at 7888 but I can't enter anything. Any ideas ?

I'm running with both:

./gradlew -q clojureRepl

./gradlew clojureRepl

Cheers

Hi,

Its long back that I did the set up. But what I can remember is that I got the Clojure REPL prompt at the console after this. However I wrote a blog post of my set up activities and my findings. Please refer to that and see if that helps you.

Post is "Clojure with Emacs 23" at https://programmerscratchpad.wordpress.com.

As a side note I shall like to mention that I am using Clojure with Emacs and inf-clojure minor mode.

Thanks and regards
Santanu

Oh, I think I got it wrong.

./gradlew clojureRepl

This runs a repl server on the selected port, but it doesn't return a clojure repl. I could connect then to that server by using leiningen or cider or whatever the clojure client I want to use.

Is there any way to return a local repl ?

[.Santanu Chakrabarti]

Have you got a chance to read my blog post? I referred my gradle.build file there for the requirement that you mentioned.

But there is some issue while you use it from plain command shell probably due to limited console support by Gradle itself. However using this local repl with inf-clojure mode in Emacs is a piece of cake. I am happy using it that way.

Regards
Santanu

Hi,

having a local level will probably not happen any time soon, since
gradle doesn't support this stdin/stdout passing to some internal
process. I'm sorry about that.

This feature was asked for already in the past, but the gradle team
didn't assign a priority.

Bingo!!!

@Santanu Thanks. I first did a quick read and I didn't see it. Now I've seen "repl" task and that's exactly what I was looking for.

@Meikel Why Santanu solution is not good enough ? I'm more than happy having that repl. Executing:

./gradlew -q repl

It prompts the clojure console. It lacks some features, I know (autocompletion for example), but at least you have your code available in the repl ready to go.

BTW Very useful plugin Meikel
