在STS 4（Eclipse 4.21.0）中打开.aj文件时出错。

Question

更新日期：2021年11月15日

看起来这个问题可能已经被报告了，但修复程序尚未发布。https://bugs.eclipse.org/bugs/show_bug.cgi?id=575897。

如果有人有解决方法，仍然会很感激。

目前我可以使用其他编辑器编辑文件，但这是一个很大的麻烦。

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”，并抛出以下异常。

此外，如果我只是单击包资源管理器中的.aj文件，就会弹出一个弹窗，显示“发生问题”和“发生错误。请参阅错误日志以获取更多详细信息。”和相同的异常。日志只包含相同的异常。

它似乎与Equinox有关，因此我尝试从STS 4中卸载Equinox，但由于其他插件依赖于它，我无法卸载全部内容，而错误仍然存在。

我正在使用“开箱即用”的STS 4，只进行了以下附加修改：

• AspectJ Development Tools 2.2.4.202103162301
• Maven Integration for AJDT (Optional) 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，并且我正在运行JDK 11。

请展示以!SESSION开头的错误日志。 - howlger

Equinox是Eclipse的绝对核心，负责运行所有插件，在任何堆栈跟踪中你几乎总能看到它的引用。 - greg-449

添加错误日志。 - DavidA

日志中显示的是Java 17，而不是Java 11。解决方法是使用旧版本的Java，因为Java 17对非法访问的限制比旧版本更严格。 - greg-449

@greg-449 是的，Eclipse AJDT bug 575897。我已将其添加为答案。既然你先回答了这个问题，我会删除我的答案。 - howlger

我没有意识到它没有使用JAVA_HOME/path。我已经更新了.ini文件以指向Java 11，但异常仍然发生。我已经在上面包含了.log会话开始记录。 - DavidA

Answer 1

更新于2022年11月19日：AspectJ IDE设置说明解释了如何从自定义更新站点安装AJDT（而不是从Eclipse Marketplace）。只需尝试适合您的Eclipse版本的那个（如果您的Eclipse版本比那里提到的最新版本更高，则使用最新版本）。

---

感谢您提出这个问题。我没有订阅AJDT和AspectJ Bugzilla项目，即当我今天阅读这个问题时才注意到有些事情出了问题。

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

这个问题是由于AJDT与Eclipse 2021-09不兼容所致，原因是JDT Core中的API发生了变化。同样的变化并未影响当前发布候选版1.9.8.RC2中的AspectJ，但AJDT似乎访问了继承层次结构中一个以前受保护的祖先类字段。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：虽然我帮助维护AspectJ和AspectJ Maven插件（组ID dev.aspectj），但AJDT多年来没有专门的维护者，仅由AspectJ团队维护，该团队主要由Andy Clement组成，现在由我组成，因为Andy非常忙碌（我也很忙碌，只是稍微少一点）。术语“保持活力”意味着，我们做了和正在做的最低限度的工作，以使AJDT编译并且对于主要用例不会引发任何nasty exceptions。我对OSGi一般和Eclipse插件特别没有任何了解，即我在那里作为业余爱好者进行修补。很抱歉没有更好的消息。

今天在空闲时间，我升级了AJDT中的AspectJ并经历了大量Eclipse API更改，需要进行调整，不仅仅是补丁中提到的。目前，我不知道如何修复它们。这将是试错的过程，而我只有偶尔有时间，所以我无法预测何时能够发布一个可用的AJDT版本。

---

更新：我已经发布了一个 AJDT 版本，应该可以与 Eclipse 2021-09 兼容。请参阅我的 ADJT 问题 #575897 中的评论获取更多详细信息。

更新：我已添加了一条链接，介绍如何升级到适用于Eclipse 2021-09的新版AJDT。 - kriegaex

工作得非常好！非常感谢您抽出时间来处理这个问题！ - DavidA
