现在分析一下任务执行顺序：
:xxxxxxx:cleanCopyNativeLibs //对应了主工程的 clean.dependsOn 'cleanCopyNativeLibs'
:xxxxxxx:clean //gradle的第一步
:xxxxxxx-library:clean //lib库clean
:xxxxxxx:copyNativeLibs // copyNativeLib，对应主工程的 tasks.withType(JavaCompile) { compileTask -> compileTask.dependsOn copyNativeLibs }
:xxxxxxx:copyFlavor360 //对应了 task prepareFlavor(dependsOn: tasks.matching { Task task -> task.name.startsWith("copyFlavor") })
