[GRADLE] 1.7.2 - Cannot use external .jar ?

Hi

I'm using the apache library httpcomponents in my mod.

So I've 7 jar files, I've added in my buildpath on Eclipse.

Then compile with eclipse works. When I launch my mod with eclipse it's work.

But when I use gradle build command, the custom buildpath is'nt considered.

I see I must modify the build.gradle file. I've try ...

dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:1.2-SNAPSHOT'
        compile files('lib/httpcomponents-client/commons-codec-1.6.jar')
        compile files('lib/httpcomponents-client/commons-logging-1.1.3.jar')
        compile files('lib/httpcomponents-client/fluent-hc-4.3.3.jar')
        compile files('lib/httpcomponents-client/httpclient-4.3.3.jar')
        compile files('lib/httpcomponents-client/httpclient-cache-4.3.3.jar')
        compile files('lib/httpcomponents-client/httpcore-4.3.2.jar')
        compile files('lib/httpcomponents-client/httpmime-4.3.3.jar')
       
    }

but it's doesn't work, "Could not find method compile() for arguments [file collection] on org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler_Decorated@76454e71."

And I've try to use

dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:1.2-SNAPSHOT'
        runtime fileTree(dir: 'lib/httpcomponents-client', include: '*.jar')
    }

but I've an error too, "Could not find method runtime() for arguments [directory 'lib/httpcomponents-client'] on org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler_Decorated@40211960."

Could you help me please ?

Thanks, and sorry for my bad english

You make a separate dependencies block for them. Like this, from Ex Nihilo:

https://bitbucket.org/Erasmus_Crowley/ex-nihilo/src/febd0f3c84284cb9e363d8e8681a445611ab7616/build.gradle?at=master#cl-43

Thanks a lot, building with gradle works now

But I have an other problem, when I launch my game, it's crash because classLoader don't find externals librairies required by my mod.

What can I do to solve it please ? Thanks

Well, if you need the classes to run the program, you obviously need to put them in your mods folder. That's basic java.

Hi,

I did it, but I still have this error  :'(

Do you have any idea ? Thanks

I have exactly the same problem. Forge loads whatever you put in the mods directory, but the actual mod can't 'see' its dependencies. Perhaps they are all loaded into different class loaders.

In 1.6.4, I wrote a script to extract all the class files from the dependent libraries into the same directory as the mod itself, and jar the whole lot up together. I'm trying to figure out how to do the same in Gradle rather an a shell script. If I figure it out, I'll post it back here.

I have my idea to solve the problem.

In fact gradle uses dependencies to build the .jar but don't include referencies to external jar.

So it's like you don't know the jar after the compilation.

I think when the external jar is in your classpath (so put into your mods folder), you should do a Class.forname(), It should be works. I don't try, but will try it this week (If I have time, I hope ).

OK - the good news - I figured out the Gradle magic to include dependent JARs in your mod JAR. At the end of build.gradle, add:

configurations {
    external
    compile.extendsFrom external
}

dependencies {
    external 'org.apache.httpcomponents:httpclient:4.3.3'
    external 'org.apache.httpcomponents:httpcore:4.3.2'
    // etc
}

jar {
    from { configurations.external.collect { it.isDirectory() ? it : zipTree(it) } }
}

The bad news - mods using org.apache JARs will still not work, due to a bug in FML: https://github.com/MinecraftForge/FML/issues/424

YES! Got this all working, thanks to some input from LexManos and GUIpsp on my pull request.

The key is to use the Gradle Shadow plugin to relocate the external classes so they don't get excluded by FML, and there's no risk of clashing with different versions of the same JARs in other mods. Here's by build.gradle in its entirety, so you can see how it all works

buildscript {
    repositories {
        mavenCentral()
        maven {
            name = "forge"
            url = "http://files.minecraftforge.net/maven"
        }
        maven {
            name = "sonatype"
            url = "https://oss.sonatype.org/content/repositories/snapshots/"
        }
        jcenter()
    }

        classpath 'eu.appsatori:gradle-fatjar-plugin:0.2-rc1'
        classpath 'com.github.jengelman.gradle.plugins:shadow:0.8'
    }
}

apply plugin: 'shadow'

shadow {
    classifier = 'mod' // My mod jar ends up as build/distributions/Forcecraft-1.7.2-0.2.0-mod.jar
    artifactSet {
        include 'us.forcecraft' // My mod's main package
    }
    relocation {
        pattern = 'argo'
        shadedPattern = 'us.forcecraft.argo'
    }
    relocation {
        pattern = 'org.apache'
        shadedPattern = 'us.forcecraft.org.apache'
    }
    relocation {
        pattern = 'org.cometd'
        shadedPattern = 'us.forcecraft.org.cometd'
    }
    relocation {

        shadedPattern = 'us.forcecraft.org.eclipse'
    }
}
