maven-3 - 通过maven编译时出现SAXParseException

Question

大家好，我知道以前可能有人问过这个问题，所以提前抱歉(没有足够的代表对其他线程发表评论)

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

日志......

Answer 1

我遇到了同样的问题，问题是详细标志已打开，并且详细日志记录只是为了记录而创建错误。

XJC 代码中基本上存在一个“bug”，他们调用的地方

//生成实际代码 receive.debug("生成代码");

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。这更有趣，因为 SAXParseException 只是为了创建日志语句而创建的，并且永远不会抛出。
