can not add repository

[amangautam1]

On adding the repository in the Gradle I am getting the following error.

Java: file not found Exception Resource nexus-maven-repository-index-properties does not exist

Hi,

How are you adding koma to your project? For a gradle project, you'll want to add koma into the repositories block of your build.gradle file.

For example, here's a build.gradle for a Java project thats configured to use koma:

apply plugin: "java"
apply plugin: "application"

mainClassName="Hello"

repositories { 
    maven { 
        url "http://dl.bintray.com/kyonifer/maven" 
        jcenter()
    } 
}
dependencies{
    compile "koma:backend-matrix-mtj:0.10"
    compile "koma:core:0.10"
}

then making src/main/java/Hello.java contain:

class Hello {
    public static void main(String [] args) {
        System.out.println(koma.Koma.zeros(3,3));
    }
}

now running it on the command line I get:

❯ gradle run
:compileJava UP-TO-DATE
:processResources NO-SOURCE
:classes UP-TO-DATE
:run
mat[ 0.00,  0.00,  0.00 end
     0.00,  0.00,  0.00 end
     0.00,  0.00,  0.00 ]

If you're running things from intellij make sure you refresh the gradle project after changing the build.gradle file.

If you're using maven instead of gradle you can find the xml snippet here to add.

this is my gradle file and i am still getting same error.

version '1.0-SNAPSHOT'

buildscript {
    ext.kotlin_version = '1.1.3-2'

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: 'kotlin'
apply plugin: 'application'

mainClassName = "_DefaultPackage"

repositories {
    maven {
        url "http://dl.bintray.com/kyonifer/maven"
        jcenter()
    }
}
dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
    compile "com.marcinmoskala:DiscreteMathToolkit:1.0.2"
    compile 'com.github.kevinsawicki:http-request:6.0'
    compile "koma:backend-matrix-mtj:0.10"
    compile "koma:core:0.10"

}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

I can't reproduce. With your build.gradle I get:

❯ gradle build
:compileKotlin

What does gradle build give you?

Doing a search for your error leads to here, which notes there's an open issue for user bintray repositories not indexing correctly in intellij. This appears to be the exact issue you're running into.

Following the steps noted in that bug report (pressing 'Update' in File | Settings | Build, Execution, Deployment | Build Tools | Maven | Repositories for the created repository) I'm able to reproduce your error. Reimporting the project eliminates it until I try to update the repository index again.

Closing this as I'm fairly confident this isn't anything to do with koma and is the above bug in intellij's indexer.
