IntelliJ中Codename One插件无法加载问题求助

各位好，我最近在Windows 11的IntelliJ里用Codename One开发时遇到了个棘手的问题，想请大家帮忙支招：

我已经把Codename One的Git仓库关联好了，IDE安装在C:\eclipse\IntelliJ路径下。但当我打开CN1设置尝试安装BrainTree插件时，直接失败了，插件完全加载不出来。下面是完整的Maven报错日志：

我自己初步看了下，日志里有两个明显的问题：

• 首先是Maven项目里有重复的依赖声明：com.codenameone:codenameone-core和com.codenameone:codenameone-javase都重复声明了版本
• 核心报错是找不到com.sun:tools:jar:1.8.0，路径指向C:\eclipse\Java_JRE_8/../lib/tools.jar，看起来是JRE路径的问题？

有没有朋友遇到过类似的情况？或者能告诉我该怎么一步步解决这两个问题，顺利装上插件吗？
