导入后ANTLR4语法标记识别错误

我正在使用GitHub中的antlr4 解析器语法词法分析器语法来解析Python3中的PHP.

当我直接使用这些语法时,我的PoC代码可以工作:

antlr-test.py

from antlr4 import *
# from PHPParentLexer import PHPParentLexer
# from PHPParentParser import PHPParentParser
# from PHPParentParser import PHPParentListener

from PHPLexer import PHPLexer as PHPParentLexer
from PHPParser import PHPParser as PHPParentParser
from PHPParser import PHPParserListener as PHPParentListener


class PhpGrammarListener(PHPParentListener):
    def enterFunctionInvocation(self, ctx):
        print("enterFunctionInvocation " + ctx.getText())


if __name__ == "__main__":
    scanner_input = FileStream('test.php')
    lexer = PHPParentLexer(scanner_input)
    stream = CommonTokenStream(lexer)
    parser = PHPParentParser(stream)
    tree = parser.htmlDocument()
    walker = ParseTreeWalker()
    printer = PhpGrammarListener()
    walker.walk(printer, tree) …

使用Spring 3,maven,JPA,c3p0在hibernate中"java.lang.NoSuchFieldError:NONE"

问题:

Hibernate没有正确执行查询.它出现问题似乎与slf4j有关,但使用任何推荐的修复似乎不起作用.

我已经为createQuery调用尝试了各种变量名称组合,希望我是在做错误(TM),但到目前为止还没有运气.这个问题真让我难过,有没有人遇到过类似的东西?

堆栈跟踪:
