在 Eclipse IDE 中 pom.xml 的第 1 行出现未知错误。直到昨天它工作正常，但是在从 master 更新我的项目并修复合并冲突后突然在 pom.xml 中出现“未知错误”。除了我，我的队友都没有遇到这个问题。我还更改了工作区，删除了缓存，但仍然没有运气。
我在这个项目中使用了 h2 数据库，尽管在 data.sql 中插入了值，但它没有获取任何值并插入到 h2 DB 表中。在这个问题之前，它工作正常。我觉得这是由于 pom.xml 中的问题，但我不确定。请帮忙
我删除了现有的项目，并从 master 那里获取了最新的代码。之后删除用户下的 .m2 文件夹，包括存储库文件夹。我确实更新了项目并启用了快照/版本的强制更新、maven clean 和 maven build。但没有任何帮助。

应该删除 pom.xml 中的未知错误，并且我必须能够在 H2 db 中填充值。

A less profound change than a downgrade from Spring Boot
2.1.5.RELEASEto2.1.4.RELEASEwould be downgrading only the affected Maven JAR Plugin from3.1.2to3.1.1只要存在此错误：
