因为要升级sdk，需要升级gradle，引擎版本是2.4.3，项目默认发布项目能编译打包，都是正常的，这时候项目的gradle是4.1.3，这个是正常的，但是升级后编译就报错了
Build file ‘D:\ccbuild\jsb-default\frameworks\runtime-src\proj.android-studio\game\build.gradle’ line: 106
Execution failed for task ‘:game:mergeDebugFeatureAssets’.
Could not copy file ‘D:\ccbuild\jsb-default\assets\Fxgz_id’ to ‘D:\ccbuild\jsb-default\frameworks\runtime-src\proj.android-studio\game\property(interface org.gradle.api.file.Directory, fixed(class org.gradle.api.internal.file.DefaultFilePropertyFactory$FixedDirectory, D:\ccbuild\jsb-default\frameworks\runtime-src\proj.android-studio\game\build\intermediates\merged_assets\debugFeature\out))\assets\Fxgz_id’.
复制资源出错了。请求各位大佬帮助
