如何确定哪些文件会影响孵化器netbeans的构建?

我正在经历以下情况 ant 的生成失败 incubator-netbeans 项目:

我在那里报告的 https://issues.apache.org/jira/browse/NETBEANS-787 . 它没有引起注意,因为我不能在任何CI服务上、在Ubuntu Docker映像或在VirtualBox映像中复制它,实际上只有在我的Ubuntu 18.04上(因此,问题应该具有低优先级,我假设检查问题跟踪程序的开发人员正在处理它,因此我想,我可能会找到一种自我复制的方法。

由于删除源根和新克隆并不能解决问题,因此我需要找到导致失败的文件(我假设只有源根之外的配置文件才是原因)。这可能是我想不出的其他原因。我不记得是否在源根目录之外设置过什么。

我可能会等待构建系统迁移到Maven(这个想法流传了多少年?),但我认为它不是解决这个特定问题的有效方法:)
