eclipse - 在 STS 4 (Eclipse 4.21.0) 中打开 .aj 文件时出错

Question

2021 年 11 月 15 日更新

而且看起来这可能已经被报告过，只是修复还没有发布。 https://bugs.eclipse.org/bugs/show_bug.cgi?id=575897

如果有人有解决方法，我们将不胜感激。

我现在可以在不同的编辑器中编辑文件，但这是一个很大的痛苦。

原始问题

无法在 STS 4.12.1.RELEASE 中打开 aspectj 文件 (*.aj)

每当我尝试打开 .aj 文件时，Eclipse 都会给出错误“无法初始化编辑器”并引发以下异常。

此外，如果我在 Package Explorer 中简单地单击一个 .aj 文件，就会出现一个弹出窗口，显示“出现问题”和“发生错误。请参阅错误日志了解更多详细信息。”和同样的异常(exception)。日志仅包含相同的异常。

它似乎与 equinox 有关，所以我尝试从 STS 4 中卸载 Equinox，但无法卸载所有(显然是由于依赖于它的其他插件)，并且错误仍然存​​在。

我正在“开箱即用”地使用 STS 4，仅进行了以下额外修改:

• AspectJ 开发工具 2.2.4.202103162301
• AJDT 的 Maven 集成(可选)0.14.0.201302011330
• Lombok 1.18.22

我的 maven 项目依赖于 AspectJ 1.9.7 和 maven-aspectj-plugin 1.14.0，我正在运行 JDK 11。

Answer 1

2022-11-19 更新: AspectJ read-me for IDE setup解释如何从自定义更新站点(而不是从 Eclipse Marketplace)安装 AJDT。只需尝试适合您的 Eclipse 版本的那个(如果您的 Eclipse 版本比此处提到的最新版本更新，则尝试最新的可用版本)。

---

感谢您提醒我注意这个问题。我没有订阅 AJDT 和 AspectJ Bugzilla 项目，也就是说，我今天在阅读这个问题时才注意到有问题。

java.lang.IllegalAccessError:
  class org.eclipse.ajdt.core.javaelements.AJCompilationUnit
  tried to access private field
  org.eclipse.jdt.internal.core.JavaElement.parent 

该问题是由于 JDT Core 中的 API 更改导致 AJDT 与 Eclipse 2021-09 不兼容引起的。相同的更改不会影响当前候选版本 1.9.8.RC2 中的 AspectJ，但 AJDT 似乎可以从继承层次结构中向上的祖先类访问以前 protected 字段。这需要调整为使用 getter 方法，正如附加到 AJDT Bugzilla 问题的补丁所示。

背景:虽然我正在帮助维护 AspectJ 本身和 AspectJ Maven 插件(组 ID dev.aspectj)，但 AJDT 多年来一直没有专门的维护者，只是由 AspectJ 团队维持活力，该团队主要使用由 Andy Clement 和现在的我组成，因为 Andy 非常忙(我也是，只是少了一点)。术语“保持事件状态”意味着，我们已经并且正在做最低限度的工作以保持 AJDT 编译并且不为主要用例抛出任何令人讨厌的异常。我对一般的 OSGi 和特别是 Eclipse 插件的了解为零，即我作为一个业余爱好者在那里打补丁。很抱歉没有更好的消息。

今天在一个安静的时间里，我从 AJDT 中的 AspectJ 升级了一些上游的东西，经历了一大堆需要调整的 Eclipse API 更改，而不仅仅是补丁中解决的那个。目前，我不知道如何修复它们。这将是反复试验，我偶尔只有一次时间，所以我无法预测我何时可以发布一个可用的 AJDT 版本。

---

更新:我已经发布了一个 AJDT 版本，它应该可以与 Eclipse 2021-09 一起使用。看我的comment in ADJT issue #575897了解更多详情。
