JavaCC新手,不知道发生了什么。 我在JavaCC中有以下语法
<START_EXPR>
(operator = <AND> | operator = <OR> | operator = <NOT>)
(CondPassOperator(passingCondition) | VariableComparepassingCondition))+
<END_EXPR>
<START_EXPR : "(">
|
<END_EXPR : ")">
当我编译它低于警告时,
[javacc] line 699, column 10 and line 699, column 58 respectively.
[javacc] A common prefix is: "("
[javacc] Consider using a lookahead of 2 for earlier expansion.
知道为什么我会收到这个警告吗?这个警告使我的TeamCity构建失败。
