Not able to copy configurations dependencies after upgrading Gradle plugin for Android Studio to 3.0.1 and Gradle to 4.1

Question

I used to copy \'compile\' dependencies to a specific folder using this simple gradle task :

task copyLibs(type: Copy) {
    from configurations.compile

This probably won't help or have a better way to solve but...

You can put your dependencies in a way that is possible to copy doing the following:

android { ... }

// Add a new configuration to hold your dependencies
configurations {
    myConfig
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support:support-v4:26.1.0'
    implementation 'com.android.support:design:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

    // Now you have to repeat adding the dependencies you want to copy in the 'myConfig'
    myConfig fileTree(dir: 'libs', include: ['*.jar'])
    myConfig 'com.android.support:appcompat-v7:26.1.0'
    myConfig 'com.android.support:support-v4:26.1.0'
    ...
}

task copyLibs(type: Copy) {
    // Now you can use 'myConfig' instead of 'implementation' or 'compile' 
    from configurations.myConfig 
    into "$project.rootDir/reports/libs/"
}

This also helps if you have a Jar task that stops placing the dependencies in to the jar file because you changed from compile to implementation.

You can use:

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

Instead of:

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