将Gradle依赖项保存到目录

Question

How can I save all the dependent jars for a module to a directory? I have an application that runs in IntelliJ IDEA, but I want to run it on another computer so I need to copy all the JAR files there.

Answer 1

Firstly, please consider using Gradle (or Gradle Wrapper) to do such things like getting/downloading dependencies of a project on another computer. But if you need to copy dependencies for any other reason you can define a task similar to:

task copyDependencies(type: Copy) {
    from configurations.runtime
    into "lib"
}

When you run:

gradle copyDependencies

runtime dependencies will be copied to a lib/ folder.

Example

build.gradle

apply plugin: 'groovy'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.codehaus.groovy:groovy-all:2.3.11'
    compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.9.1'
    compile group: 'com.h2database', name: 'h2', version: '1.4.196'

    testCompile group: 'org.spockframework', name: 'spock-core', version: '1.1-groovy-2.4'

}
task copyDependencies(type: Copy) {
    from configurations.runtime
    into "lib"
}

Command:

gradle copyDependencies

And lib/ directory contains:

lib
├── groovy-all-2.3.11.jar
├── h2-1.4.196.jar
└── jackson-core-2.9.1.jar

Use Gradle Wrapper

As I mentioned earlier, please consider using Gradle Wrapper so you don't have to worry about if there is a Gradle distribution installed on another computer. As stated in the documentation you can easily add Gradle Wrapper and then you can run

./gradlew [task]

by using wrapper instead of Gradle installed on your OS. In your case running

./gradlew build 

will download all dependencies and build the project. It's way better than copying dependencies manually, Gradle was invented to do it for us.

Answer 2

following solution worked for me

configurations.implementation.setCanBeResolved(true) 
configurations.api.setCanBeResolved(true)
task copyDependencies(type: Copy) {
    from configurations.implementation  
    into "libs" 
}
