Question

大家好我知道之前可能会有这样的问题，所以提前抱歉（havnt有足够的代表在其他帖子上发表评论）

当我通过mvn编译我的项目时，我得到一些SAXParse异常，即使我可以构建和运行我的项目没问题。我只是清理一些构建警告，并想知道为什么会发生这种情况......任何帮助都非常感激

我遇到了同样的问题，问题是verbose标志已打开，而verbose的日志记录只是为了记录而创建错误。

XJC代码中基本上存在“错误”，他们调用

//generate actual code receiver.debug("generating code");

并编写调试语句

public final void debug( String msg ) {
    info( new SAXParseException(msg,null) );
}

然后调用

public void info(SAXParseException exception) {
    if(opt.verbose)
       super.info(exception);
 }

因此，由于记录器的实现方式，它会记录完整的堆栈跟踪。查找起来更有趣，因为SAXParseException仅用于创建日志语句，并且永远不会被抛出。

通过maven编译时出现SAXParseException
