Question

当我进行调试构建时，java资源被打包到jar而没有任何问题。但是，它不适用于发布版本。我注意到gradle任务processReleaseJavaRes仅针对调试版本执行。我搜索了android gradle代码并找到了以下lines of code:

if (variantConfig.buildType.runProguard) {
    // run proguard on output of compile task
    createProguardTasks(variantData, null)
    // hack since bundle can't depend on variantData.proguardTask
    mergeProGuardFileTask.dependsOn variantData.proguardTask
    bundle.dependsOn packageRes, packageAidl, packageRenderscript, mergeProGuardFileTask, lintCopy, variantData.ndkCompileTask
} else {
    Sync packageLocalJar = project.tasks.create("package${variantData.variantConfiguration.fullName.capitalize()}LocalJar",Sync)
    packageLocalJar.from(getLocalJarFileList(variantData.variantDependency))
    packageLocalJar.into(project.file("$project.buildDir/$DIR_BUNDLES/${variantData.variantConfiguration.dirName}/$SdkConstants.LIBS_FOLDER"))
    // jar the classes.
    Jar jar = project.tasks.create("package${buildType.name.capitalize()}Jar", Jar);
    jar.dependsOn variantData.javaCompileTask, variantData.processJavaResourcesTask
    jar.from(variantData.javaCompileTask.outputs);
    jar.from(variantData.processJavaResourcesTask.destinationDir)
    ...
    bundle.dependsOn packageRes, jar, packageAidl, packageRenderscript, packageLocalJar, mergeProGuardFileTask, lintCopy, variantData.ndkCompileTask
    ...
}

然后我尝试将任务添加为proguardRelease的依赖：

tasks.whenTaskAdded { task ->
    if (task.name.matches("proguardRelease")) {
        task.dependsOn('processReleaseJavaRes')
    }
}

这很好用，java资源是在build / intermediates / javaResources /中创建的 - 但是接下来出现了问题。我如何告诉proguard它应该使用build / intermediates / classes中的类构建jar，还包括build / intermediates / javaResources中的资源？我试图用-injars设置javaResources路径。现在将它们添加到proguard中（参见下面的日志输出），但不会添加到build / intermediate / bundles / release / classes.jar中的classes.jar中。

我遇到了同样的问题，filed an issue for the project

与此同时，我使用以下代码片段来解决此问题：

android.libraryVariants.all { variant ->

    def proguardTask = variant.obfuscation
        if (proguardTask != null) {
            proguardTask.doFirst {
                copy {
                    from variant.processJavaResources.destinationDir
                    into variant.javaCompile.destinationDir
                }
            }
        }
}

它会将java res文件夹复制到classes文件夹，它将包含在最终的jar中。

我还没有找到解决方案，但我解决了这个问题：我只是手动运行任务，然后从java资源和模糊的jar文件中创建一个jar：

android.libraryVariants.all { variant ->
    variant.outputFile = file("${project.buildDir}/outputs/aar/${project.archivesBaseName}-${variant.baseName}.aar");

    if(variant.buildType.name.matches("release")) {
        tasks.create(name: "enriched${variant.name.capitalize()}Jar", type:Jar, dependsOn:variant.processJavaResources) {
            from zipTree("${project.buildDir}/intermediates/bundles/${variant.dirName}/classes.jar") // add original content
            from fileTree("${project.buildDir}/intermediates/javaResources/${variant.dirName}/")
            destinationDir(file("${project.buildDir}/intermediates/bundles/${variant.dirName}/"))
            includeEmptyDirs false
            archiveName 'classes_full.jar'
        }

        tasks.create(name: "fix${variant.name.capitalize()}Files", type:Delete, dependsOn:"enriched${variant.name.capitalize()}Jar") {
            delete "${project.buildDir}/intermediates/bundles/${variant.dirName}/classes.jar"
            doLast{
                file("${project.buildDir}/intermediates/bundles/${variant.dirName}/classes_full.jar").renameTo(file("${project.buildDir}/intermediates/bundles/${variant.dirName}/classes.jar"))
            }
        }

        variant.packageLibrary.dependsOn "fix${variant.name.capitalize()}Files"
        tasks["fix${variant.name.capitalize()}Files"].mustRunAfter variant.obfuscation
    }
}

当我用gradle和proguard构建我的android库时，缺少Java资源文件
