Configuration on demand is an incubating feature.
Incremental java compilation is an incubating feature.

BUILD SUCCESSFUL

Total time: 29.684 secs

仔细看log发现copyNativeLibs执行在native build之前，这导致每次改C++代码后的第一次 Run ‘GameApp’ 时修改并没有生效~~~

#2

添加task的第二个参数指定上一个task依赖

#3

你按照这个 pr 修改下看看？

https://github.com/cocos-creator/cocos2d-x-lite/pull/758/files

#4

您试过吗？
我用这个fix，sync的时候不报错，但是build的时候会报如下错

在debug mode下，可以用 ‘externalNativeBuildDebug’，但不能用’externalNativeBuildRelease’；
但在release mode（android studio中Build Variants中每一个都设置成release）下，两者皆可用
原因不明

试过啊，我这都没问题的
你把 gradle 升级下看看 ？
