java - Maven 清理后不编译。“找不到标志”
问题描述
我已阅读有关“找不到符号”maven 错误的所有问题,但我想它们不适合我。
首先,我使用 Eclipse 开发了一个教育项目。这是一个简单的聊天,可以在 github上访问。它编译并运行良好,但现在我需要在没有 Eclipse 而是使用 Maven 的情况下编译它。我跑了mvn clean
,mvn validate
(都成功了)。然后mvn compile
我得到错误:

而且,在那之后,即使是 Eclipse 也无法正常运行项目。附加字符串出现在起始日志中:
2020-06-17 11:20:15.433 INFO 16244 --- [ main] .s.s.UserDetailsServiceAutoConfiguration :
Using generated security password: fe0f803b-2116-43b6-910c-47e5b11b168b
并且出现了一些默认的 spring 安全登录页面,而不是我的自定义页面。当我在 Eclipse 中制作“Project -> Clean”时,这些问题就消失了。
如果我通过 Eclipse 清理和运行项目,而不是用 maven 编译它(没有mvn clean
),它也是成功的。
我完全意识到依赖项或导入存在一些问题,但我不知道究竟是什么。我什至用相同的 POM 创建了一个新项目——maven 成功编译了它。我在下面提供我的 POM:

谢谢你的任何想法!
解决方案
问题出在java版本中。仅从第 9 个 jdk 开始支持方法 readAllBytes() 。我没有提到它,因为我的 POM 中有 java 版本 1.8,但 Eclipse 在它安装的库中有 jdk 14 并以某种方式将其用于编译。
