【问题描述】：
我使用的是 eclipse 2021-3（详细版本如下），在 GUIBuilder 中更新我的表单后，我注意到表单类中的 initGuiBuilderComponents java 方法为空，但 .gui 文件中声明了组件。
在 GUIBuilder 中保存更改后得到的堆栈跟踪是：
enGuiSrc:
[generateGuiSources] Generating GUI sources
[generateGuiSources] timeStr=1.0.0-1621275794779-1621275373210, lastTime=1.0.0-1621275794779-1621275373210

如果这是新 Eclipse 的框架问题，有任何线索吗？
