问题描述
在我的 Android 项目中，我有一个将构建依赖项复制到外部目录的任务，如下所示:
task copyBuildDependencies(type: Copy) {删除$buildDir/dependencies"后评价{从configuration.releaseCompileClasspath进入$buildDir/dependencies"最后一个{FileTree files = fileTree("$buildDir/dependencies")files.forEach { 文件 ->if (file.isFile() && file.name.endsWith(".aar")) {复制 {来自 zipTree(file).matching { 包括*.jar"}进入$buildDir/dependencies"每个文件{it.path = it.path.replace(it.name, "${file.name}-${it.name}")}}}}}}}我有项目依赖项的正常依赖项:
依赖项{实现文件树(包括:['*.jar']，目录:'libs')...实现 'com.google.guava:guava:11.0.2'实现org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"实现 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.22.5'实现 'org.jetbrains.kotlinx:kotlinx-coroutines-android:0.22.5'//注意:这些是 Android 库项目实施项目(':genericutils')实施项目(':module2')...}当我运行任务 copyBuildDependencies 时，我收到以下错误:

我创建了一个示例项目来帮助显示我所追求的结果和我遇到的问题:
此外，您可以像我上面编辑的那样简单地修改 modulesExcluded 数组.并且可以删除hasProperty()"的条件检查.
输出将在$rootDir/dependencies"下.类似于以下内容:
- 调试
- genericutils-debug.jar
- mastermodule-debug.jar
- 发布
- genericutils-release.jar
- mastermodule-release.jar
这些 jars 是从您自己的源代码生成的，即您的 genericutils 和 mastermodule 源.如果库的传递依赖是.jar"格式，它们将进入.aar的libs/"，如果它们是.aar"格式，我认为你不能简单地选择它的 classes.jar 而是去掉它的相关和必要的部分，除非你有一些特殊的要求和那些缺少的部分与您的项目无关.
-------- 编辑 2 ---------
如果您只关心源代码并且不在您的代码逻辑中使用任何资源(res、R.txt、aidl、jni 等)，例如可能您的 genericutils 模块就是这种情况，那么您只需选择 classes.jar 即可.当您将其用作普通 Java 库时，它不会引起任何问题.
In my Android project I have a task for copying the build dependencies to an external directory as below:
task copyBuildDependencies(type: Copy) {
delete "$buildDir/dependencies"
afterEvaluate {
from configurations.releaseCompileClasspath
into "$buildDir/dependencies"
doLast {
FileTree files = fileTree("$buildDir/dependencies")
files.forEach { file ->
if (file.isFile() && file.name.endsWith(".aar")) {
copy {
from zipTree(file).matching { include "*.jar" }
into "$buildDir/dependencies"
eachFile {
it.path = it.path.replace(it.name, "${file.name}-${it.name}")
}
}
}
}
}
}
}
I have normal dependencies with project dependencies:
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
...
implementation 'com.google.guava:guava:11.0.2'
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.22.5'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:0.22.5'
// Note: These are Android Library projects
implementation project(':genericutils')
implementation project(':module2')
...
}
When I run the task copyBuildDependencies I get the following error:
Executing task 'copyBuildDependencies'...

BUILD FAILED in 2s
16:39:07: Task execution finished 'copyBuildDependencies'.
I can use the exclude module option on configurations.releaseCompileClasspath but then the assembleRelease task fails because it can not find the dependencies.
Edit: I have created an example project to help show the result that I am after and the issue I am having: https://gitlab.com/crunchy234/android-gradle-dependencies-export
--- Edit 2 ---
The reason for wanting the dependencies of the library module rather than the Jar for the library is so that a Xamarin Bindings library can be created.
So what is wanted for the Xamarin Bindings is the AAR for the library (mastermodule in the case of the example code) and all of the Jars for the libraries dependencies. E.g:
mastermodule/build/dependencies/
├── animated-vector-drawable-28.0.0-alpha3.aar-classes.jar
├── annotations-13.0.jar
...
├── collections-28.0.0-alpha3.jar
├── common-1.1.1.jar
├── coordinatorlayout-28.0.0-alpha3.aar-classes.jar
...
etc
解决方案
If I understand correctly
- your project is an Android library project.
- your copy task tries to copy all the jars inside the AAR library.
- rename the classes.jar.
Probably below is what you want. Add this into the build.gradle under root project.
// Add this into the build.gradle under **root** project.
// Add the modules that you want to exclude from having this copyXXXJar task.
def modulesExcluded = [
'app',
'mastermodulewantedoutput'
]
subprojects { prj ->
// Skip excluded modules
if (modulesExcluded.contains(prj.name)) {
prj.afterEvaluate {
tasks['preBuild'].dependsOn(copyModuleJars)
}
return
}
prj.afterEvaluate {
/**
* Dynamically create task "copyXXXJar" according to build variant of each library module.
*/
android.libraryVariants.all { variant ->
def capitalizedVariantName = variant.name.capitalize()
def variantName = variant.flavorName
if (!variantName || variantName == "") {
variantName = variant.buildType.name
} else {
variantName += "-${variant.buildType.name}"
}
//================================================================================
// Define build/copy variant jar and copy to dependencies
//================================================================================
def copyJarTask = project.tasks.create("copy${capitalizedVariantName}Jar", Copy) {
group "Copy Jar"
description "Rename the classes.jar to ${project.name}-${variantName}.jar and copy it into dist folder."
def fromDirModule = "$buildDir/outputs/aar/${project.name}-${variantName}.aar"
def intoDirModule = "$rootDir/dependencies/$variant.buildType.name"
from(zipTree(fromDirModule))
into(intoDirModule)
include('*.jar')
include('libs/*.jar')
rename('classes.jar', "${project.name}-${variantName}.jar")
dependsOn "assemble${capitalizedVariantName}"
}
copyModuleJars.dependsOn(copyJarTask)
}
}
}
// Task to copy all the modules' jars. It can be run with command [ ./gradlew copyModuleJars ]
task copyModuleJars {
group = 'Copy Jar'
description = 'Copy the classes.jar from each module.'
}
Run below command to verify
./gradlew copyModuleJars
Hope it helps.
--------- Edited ----------
I checked your gitlab project. It looks you only need the jar inside the .aar. I'd like to say this may cause some problems because you drop the associated res files, aidl file, assets and R.txt, etc which are considered as necessary parts of the .aar library. For example, one of your dependency aar appcompat-v7-28.0.0-alpha3, will actually have below layout when you unzip it, NOT ONLY the classes.jar.
Additionally, you can simply modify the modulesExcluded array as I edited above. And the condition check of "hasProperty()" can be removed.
The output will be under "$rootDir/dependencies". Something like below:
- debug
- genericutils-debug.jar
- mastermodule-debug.jar
- release
- genericutils-release.jar
- mastermodule-release.jar
These jars are generated from your own source code, i.e. your genericutils and mastermodule sources. If the transitive dependencies of library are in ".jar" format, they will go into "libs/" of the .aar, if they are in ".aar" format, i don't think you can simply pick its classes.jar but strip its associated and necessary parts unless you have some special requirement and those missing part don't matter with your project.
-------- Edited 2 ---------
In case that you only concern about the source code and don't use any resources (res, R.txt, aidl, jni etc) inside your code logic, e.g. probably your genericutils module will be such kind of case, then you can simply pick up the classes.jar only. It won't cause any issue when you use it as a normal Java library.
