SecurityException异常：找不到领域dex.jar机器人 [英] SecurityException: Unable to find field for dex.jar android

问题描述

昨天晚上我升级到 ADT-21 并重新启动蚀。然后蚀说你需要更新的Andr​​oid工具21的版本，我下载了 window_installer21 在我的previous window_installer被安装在相同的位置安装。因此它覆盖该文件。然后我重新启动Eclipse和突然间所有的项目停止工作。日食总是与错误打开。       SecurityException异常：找不到领域dex.jar

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

当我尝试推出一个项目，它与下面的错误停止      未知错误：无法建立：文件dx.jar不是从SDK文件夹中加载

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管理器也无法打开。

SDK Manager is also not opening.

我曾尝试：

1. 清除所有项目
2. 重新盯着日食和计算机约20-30 timmes
3. 卸载Android SDK中，Java和重新安装了
4. 设置find_java.bat文件的路径
5. 在搜索到6每小时能上网，看了一些形式

这，<一个href="http://stackoverflow.com/questions/5323684/error-while-creating-new-project-in-android">this.and <一href="http://stackoverflow.com/questions/5228453/android-adt-error-dx-jar-was-not-loaded-from-the-sdk-folder">this一也。

似乎没有任何工作。

推荐答案

则会弹出警告您更新到最新的SDK并打开相应的工具。尝试这种（多次 - 每次都要重新启动）。没有效果

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.

相反的答案是...

1. 在Eclispe的，找到你的Andr​​oid SDK中的位置。（窗口 - > preferences-> Android和SDK的位置是在页面的顶部）

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

关闭eclispe打。

Close down eclispe.

查找磁盘上的SDK - 并运行独立的SDK的manager.exe（这似乎是失败的，当第一次打开 - 但等待第二个或两个GUI的出现）。注意！ - 这是为previously由日食打开了同一个图形用户界面

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!

取所有更新的建议。出现一个对话框，表明管理工具本身已经更新，应重新启动。

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

重新启动该工具 - 建议采取任何更多的更新和关闭

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

启动eclipse！ - 这个问题已经消失

Start eclipse - the problem has gone away!
