ant checkstyle 所遇到的错误解决

        加入了开源大军,提交代码时需要ant checkstyle,这里将ant checkstyle过程中遇到的问题整理下来.方便自己也方便别人.

 

1.First sentence should end with a period  

  第一句应该以句号(.)结束,如

/**
 * util,to parse sql
 *
 */

 util.to parse sql后面没有句号而报错

2.Utility classes should not have a public or default constructor.  

   实用工具类不应该有一个默认的公共的构造函数.由于任何类都有默认的公共的无参构造函数,所以这里要在代码中加上一个私有的构造函数,如下:

private class YourClass(){ }

3.Class ParseSQLUtil should be declared as final.  

    类ParseSQLUtil应该定义为final类型,改正后代码如下:

public final class ParseSQLUtil{

}

4.File contains tab characters (this is the first instance).

5.Line does not match expected header line of ' * Licensed to the Apache Software Foundation (ASF) under one'.

  第一行要以* Licensed to the Apache Software Foundation (ASF) under one开头
