I found a way. 我找到了一个方法。 AntlrWorks 1.4 seems to have a bug. AntlrWorks 1.4似乎有一个错误。 When I pressed ctrl+shift+G to generate it did not give an error message (in fact, I got that compilation was ok) and generated a parser file only. 当我按ctrl + shift + G生成时，它没有给出错误消息（实际上，我认为编译是可以的），并且仅生成了一个解析器文件。 The cursor was not on the first line of the source file when that happened. 发生这种情况时，光标不在源文件的第一行。
WHen I pressed ctrl+shift+G in the first line, I got an error message and when I fixed those, a lexer file was generated too. 当我在第一行中按ctrl + shift + G时，我收到一条错误消息，当我修复这些错误消息时，也会生成一个词法分析器文件。
