在项目上运行构建器“AspectJ Builder”时出错

Question

我正在使用 Spring Roo 开发 SpringSource Tool Suite。直到几天前我安装了 GWT 插件后，一切都运行良好（我认为这可能是个问题，我不确定）。

每次我编写代码并按保存 (ctrl+s) 时，它都会显示一个对话框，显示

    Errors occurred during the build.

谁能帮我解决这个问题？

谢谢，

ClassFormatError 在类文件格式错误或损坏时发生。见这里：

很可能是您的 AJDT 安装以某种方式损坏。我建议尝试以下一项或全部：

1. 卸载谷歌插件。问题会消失吗？
2. 升级到 AJDT 的最新开发快照。更新站点在这里：http://download.eclipse.org/tools/ajdt/36/dev/update 升级后你的错误消失了吗？
3. 作为最后的手段，尝试重新安装 STS。您可以保留您的工作区，只需再次解压缩 STS。
