我正在使用eclipse版本：2021年9月（4.21.0）构建版本ID：20210910-1417（使用Ant）。尝试通过下面所示的上下文菜单将任何构建发送到代号为one的构建服务器时

我收到以下Java编译器错误：

在这个工作区中，我还有另外五个代号为one的项目，它们都能正常工作。同样，jar Ant任务也能正常工作。只有在尝试将构建发送到代号为one的服务器时才会出现问题。完全搞不懂这里发生了什么。以前有人遇到过这种情况吗？如果没有，关于如何诊断这个问题有什么建议吗？

如下图所示，jar在本地构建时没有问题。为什么在发送到codename one时尝试使用java编译器19.0.2，而我甚至从未在系统上安装过该编译器？
