SecurityException：无法找到dex.jar android的字段 [英] SecurityException: Unable to find field for dex.jar android

问题描述

昨天晚上我升级到 ADT-21 并重新启动eclipse。然后eclipse说你需要将android工具更新到版本21.我下载了 window_installer21 并将其安装在我之前安装的window_installer的同一位置。所以它覆盖文件。然后我重启了日食，突然间所有的项目都停止了工作。 Eclipse始终打开错误。
SecurityException：无法找到dex.jar的字段

当我尝试启动一个项目它停止与以下错误
未知错误：无法构建：文件dx.jar没有从SDK文件夹加载

SDK管理器也没有打开。

我尝试过：

1. 清除所有项目


2. 重新查看eclipse和电脑约20-30个主题


3. 卸载Android SDk，JAVA并重新安装


4. 设置find_java.bat文件的路径


5. 通过互联网搜索6小时，阅读一些表单

此，这个。和 this on e。

没有什么似乎有效。

解决方案

出现警告您更新到最新的sdk并打开相应的工具。试过这个（几次 - 每次重新启动），没有任何效果。

相反，答案是..

1. 在eclispe中，找到您的Android sdk的位置（Window-> Preferences-> Android，SDK位置位于页面顶部）。




2. 关闭eclispe。




3. 找到磁盘上的sdk - 运行独立的SDK Manager.exe第一次打开失败 - 但是等待一两秒钟，gui出现）。注意 - 这是以前由eclipse打开的gui！




4. 按照推荐使用所有更新。将出现一个对话框，指出管理工具本身已更新，并应重新启动。




5. 重新启动该工具 - 重新启动并关闭更多更新。 p>




6. 开始eclipse - 问题已经消失！

Yesterday evening I upgrade to ADT-21 and restarted eclipse. Then eclipse said that you need to update android tool to version 21. I downloaded window_installer21 and install it in the same location where my previous window_installer was installed. So it overwrite the file. Then I restarted eclipse and suddenly all project stop working. Eclipse always open with the error. SecurityException: Unable to find field for dex.jar

And when i try to launch a project it stops with the below error Unknown error: Unable to build: the file dx.jar was not loaded from the SDK folder!

SDK Manager is also not opening.

I have tried:

1. Clearing all project
2. Re stared eclipse and computer about 20-30 timmes
3. Uninstall Android SDk, JAVA and reinstalled it
4. Setting the path of find_java.bat file
5. Searched 6 hour over internet and read some form

This, this.and this one also.

Nothing seems to work.

解决方案

A popup appears warning you to update to the latest sdk and opens the appropriate tool. Tried this (several times - restarting each time) with no effect.

Instead the answer was ..

1. In eclispe, find the location of your android sdk (Window->Preferences->Android and the SDK location is at the top of the page).

2. Close down eclispe.

3. Find the sdk on the disk - and run the standalone SDK Manager.exe (It appears to fail when first opened - but wait a second or two for the gui to appear). Note - this is the same gui that was previously opened by eclipse!

4. Take all the updates as recommended. A dialog box appears indicating that the management tool itself has been updated and should be restarted.

5. Restart the tool - take any more updates recommended and close.

6. Start eclipse - the problem has gone away!
