android – 忽略外部库的proguard配置

>从aar中提取classes.jar文件,并将其作为普通jar依赖项包含在项目中(当aar包含资源时不起作用)
>更改aar并从中删除使用者proguard规则
>使用DexGuard可以过滤掉不需要的消费者规则
>做一些gradle hacking,见下文

将以下内容添加到build.gradle：

afterEvaluate {
  // All proguard tasks shall depend on our filter task
  def proguardTasks = tasks.findAll { task ->
    task.name.startsWith('transformClassesAndresourcesWithProguardFor') }
  proguardTasks.each { task -> task.dependsOn filterConsumerRules }
}

// Let's define our custom task that filters some unwanted
// consumer proguard rules
task(filterConsumerRules) << {
  // Collect all consumer rules first
  FileTree allConsumerRules = fileTree(dir: 'build/intermediates/exploded-aar',include: '**/proguard.txt')

  // Now filter the ones we want to exclude:
  // Change it to fit your needs,replace library with
  // the name of the aar you want to filter.
  FileTree excludeRules = allConsumerRules.matching {
    include '**/library/**'
  }

  // Print some info and delete the file,so ProGuard
  // does not pick it up. We Could also just rename it.
  excludeRules.each { File file ->
    println 'deleting ProGuard consumer rule ' + file
    file.delete()
  }
}

使用dexguard(7.2.02)时,您可以将以下代码段添加到build.gradle：

dexguard {
  // replace library with the name of the aar you want to filter
  // The ** at the end will include every other rule.
  consumerRuleFilter '!**/library/**,**'
}

请注意,逻辑与上面的ProGuard示例相反,consumerRuleFilter将仅包含与模式匹配的消费者规则.
