I have an external library dependency in my Android project. Like this -
dependencies {
// Example: external library
implementation 'com.example:my-external-library:1.0.0'
}
This library has assets directory in it. As a part of build process I want to copy these assets to some other directory in the project. How do I do this? I have tried something as follows but it doesn't work. I get error like Resolving dependency configuration ‘implementation’ is not allowed as it is defined as ‘canBeResolved=false’. Instead, a resolvable (‘canBeResolved=true’) dependency configuration that extends ‘implementation’ should be resolved
If I try configurations.runtimeClasspath that also doesn’t work. Could not get unknown property ‘runtimeClasspath’ for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer.
// Define the destination directory for the copied files
def destinationDir = file("$buildDir/copied-library-files")
// Create a task to copy files from the external library
task copyLibraryFiles(type: Copy) {
// Ensure this task runs after dependencies are resolved
dependsOn 'resolveDependencies'
// Get the configuration for the external library
def libraryConfiguration = configurations.implementation
// Find the JAR/AAR file for the specific library
def libraryFile = libraryConfiguration.resolvedConfiguration.resolvedArtifacts.find {
it.moduleVersion.id.group == 'com.example' && it.moduleVersion.id.name == 'my-external-library'
}?.file
// Check if the library file was found
if (libraryFile != null) {
// Copy files from the library to the destination directory
from zipTree(libraryFile) {
// Specify which files/folders to include (e.g., "assets/", "config.txt")
include 'assets/**', 'config.txt'
}
into destinationDir
} else {
println "Library file not found: com.example:my-external-library"
}
}
// Make sure the copy task runs before the build process
preBuild.dependsOn copyLibraryFiles
You can change the properties of those configurations but it's more logical to just create your own Configuration
:
configurations {
assetsLibrary
}
Then add your library to it:
dependencies {
assetsLibrary 'com.example:my-external-library:1.0.0'
}
Then you can access the files you want using configurations.assetsLibrary
.
