Open Declaration在Eclipse中停止工作

Question

我正在使用Spring Tool Suite版本3.7.3.RELEASE，而今天的Open声明快捷方式已停止F3和Ctrl + Click的无处不在。我已经阅读了许多其他类似的问题，到目前为止，没有一个解决方案有用。我已经尝试了以下所有方法：

• 重新导入所有项目
• 关闭并重新打开所有项目
• 重启Eclipse
• 进入偏好设置并手动设置提案
• 使用干净的构建运行maven更新

当我在某个变量或方法名称上按F3时，我得到下面的错误，这不是很具描述性。关于什么可能出错的任何想法或想法？

Answer 1

我遇到了同样的问题。当你不小心在Eclipse Neon中使用Eclipse Mars http://download.eclipse.org/tools/ajdt/45/dev/update/的AJDT更新站点而不是正确的http://download.eclipse.org/tools/ajdt/46/dev/update/安装AspectJ开发工具时会发生这种情况。

还有一个Eclipse错误：https://bugs.eclipse.org/bugs/show_bug.cgi?id=491030）。

使用关键字“AJDT”转到eclipse的plugins目录并搜索。删除搜索中出现的所有jar。重启eclipse，你的问题应该解决了。您需要重新安装AJDT插件。
