安装 AJDT 我得到了一个插件 org.eclipse.jdt.ui 无法加载类 org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor

Installing AJDT I got a Plug-in org.eclipse.jdt.ui was unable to load class org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor

提问by user1274399

After I install the AJDT 2.2.3 on Rational Software Archtect, every Editor displays the error: Plug-in org.eclipse.jdt.ui was unable to load class org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor I am using the Rational Software Architect 9 with Eclipse 4.2.2. Used the link (http://download.eclipse.org/tools/ajdt/42/update) to install the AJDT. Searching on the web I found this:http://www.eclipse.org/forums/index.php/t/74968/), but removing the Data Tools did not work for me. I also updated the Data Tools to 1.10.2, and yet not working.

在 Rational Software Archtect 上安装 AJDT 2.2.3 后，每个编辑器都显示错误：插件 org.eclipse.jdt.ui 无法加载类 org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor 我正在使用带有 Eclipse 4.2.2 的 Rational Software Architect 9。使用链接 ( http://download.eclipse.org/tools/ajdt/42/update) 安装 AJDT。在网上搜索我发现这个：http: //www.eclipse.org/forums/index.php/t/74968/），但删除数据工具对我不起作用。我还将数据工具更新到 1.10.2，但仍然无法正常工作。

Can anybody help me?

有谁能够帮助我？

Adding more info: I was searching for the installed JRE in preferences, but when I click Preferences -> Java I got an error: "An error has occurred when creating this preference page." And when I try the "Installed JRE's I got a popup: "Unable to create the selected preference page. An error occurred while automatically activating bundle org.eclipse.jdt.debug.ui(1537)" Another thing I am not sure if it is clear. The Editors I was mentioning were the Java File Editor, The Package Explorer, the Java View. I tryed to open an .xml file and it seems to work fine.

添加更多信息：我在首选项中搜索已安装的 JRE，但是当我单击首选项 -> Java 时出现错误：“创建此首选项页面时发生错误。” 当我尝试“已安装的 JRE”时，出现一个弹出窗口：“无法创建选定的首选项页面。自动激活包 org.eclipse.jdt.debug.ui(1537) 时发生错误”另一件事我不确定是否清楚。我提到的编辑器是 Java 文件编辑器、包资源管理器、Java 视图。我试图打开一个 .xml 文件，它似乎工作正常。

Another fix for this problem (as I have seen myself) can be to delete the following file and restart eclipse:

此问题的另一个解决方法（正如我自己所见）可以是删除以下文件并重新启动 eclipse：

.metadata/.plugins/org.eclipse.jdt.core/variablesAndContainers.dat

This path start in the %workspace% directory.

此路径从 %workspace% 目录开始。

I had the same problem when installing AJDT on Rational Software Architect 9. I also tried to remove the Data Tools but this did not worked.

我在 Rational Software Architect 9 上安装 AJDT 时遇到了同样的问题。我也尝试删除数据工具，但这没有奏效。

I fixed this by following the instructions provided here for the same problem on RAD: https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014816025

我按照此处针对 RAD 上相同问题提供的说明修复了此问题：https: //www.ibm.com/developerworks/community/forums/html/topic?id =77777777-0000-0000-0000-000014816025

In resume:

在简历中：

1. From a command line, issuing the command to destroy the shared cache as follows, while RSA is NOT running:

   "C:\Program Files\IBM\SDP\jdk\bin\java.exe" -Xshareclasses:destroyAll

2. Restart RSA

1. 在 RSA 未运行时，从命令行发出如下命令来销毁共享缓存：

   "C:\Program Files\IBM\SDP\jdk\bin\java.exe" -Xshareclasses:destroyAll

2. 重启 RSA

I've got the same error after upgrading to Win 8.1. In my case the %workspace%/.metadata/.plugins directory was suddenly write-protected. To remove the lock I had to rename the directory, create a new directory name .plugins and finally the contents from the renamed to the new directory.

升级到 Win 8.1 后，我遇到了同样的错误。在我的例子中，%workspace%/.metadata/.plugins 目录突然被写保护了。要解除锁定，我必须重命名目录，创建一个新目录名称 .plugins，最后将重命名的目录中的内容添加到新目录中。

Disable JDT weaving (select window go to Preferences -> JDT weaving, it will restart automatically).

禁用 JDT weaving （选择窗口转到 Preferences -> JDT weaving，它会自动重启）。

我面临的问题是插件 org.eclipse.ajdt.ui 无法加载类 org.eclipse.ajdt.internal.ui.ajde.CachedRuntimeClasspathEntryResolver。在启动 eclipse 时。然后我知道这是一个 AJDT 错误。所以点击eclipse中的帮助按钮->安装新软件->使用文本框类型AspectJ功能和相关工具-或http://download.eclipse.org/tools/ajdt/46/dev/update安装相关软件重新启动 eclipse 它将运行良好。
