请问一下代码生成器的问题
依照https://github.com/enilu/nutzwk-code-generator
1. 执行wk-code模块里的Generator类，没有生成代码，log结果如下

[DEBUG] 12:26:28.839 org.nutz.resource.Scans.printLocations(Scans.java:527) - Locations count=80 time use 116ms
[DEBUG] 12:26:28.853 org.nutz.resource.Scans.scan(Scans.java:280) - Found 1 resource by src( code/code.json ) , regex( ^(.+[.])(js|json)$ )

2.若安装Intellij 插件执行，只在数据库中生成对应的表。
3.中途出现过

folder or file like '^(.+[.])(js|json)$' no found in /code/code.json

能解释一下，这个配置的用处吗
