Add external jar in gradle

问题

How can I add an external library in gradle? My build.gradle contains:

buildscript {
    repositories {
        mavenCentral()
        maven {
            name = "forge"
            url = "http://files.minecraftforge.net/maven"
        }
        maven {
            name = "sonatype"
            url = "https://oss.sonatype.org/content/repositories/snapshots/"
        }
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:1.1-SNAPSHOT'
    }
}

My root folder is /FORGE/. I want to add /FORGE/build/libs/spigot.jar as a dependency.

回答1:

As explained in the documentation:

dependencies {
    compile files('libs/spigot.jar')
}

The above will add the libs/spigot.jar file to the compile configuration. You can of course add it to any other configuration (runtime, etc.).

Note that using build/libs is an extremely bad idea, since the whole build directory will be deleted as soon as you execute gradle clean. The build directory is used to store artifacts generated by the build.
