java - 在构建新的 Android 应用程序期间没有 project.properties 文件和 NullPointerException

Question

我很难解决一个问题，这个问题使我无法在 ADT 中使用新的 Android 应用程序向导来创建新的 Android 项目。首先介绍一点背景。我已经使用 ADT(ADT bundle )大约 6 个月了，没有遇到任何问题。因为目前的问题只是在尝试创建新项目时出现(构建现有项目没有问题)，而且我有一段时间没有创建新项目，我不知道是什么原因导致的。我能想到的两件事是:

1. 我最近将我的操作系统更新为 Mavericks。
2. 我最近安装了 JDK 7(我一直在使用 6)

有人问过类似的问题 here 和 here ，但答案的质量对我来说似乎不太好。一方面，除非这是一个合法的错误，否则我真的不想要解决方法。这对我来说似乎不是一个错误，因为我认为会有更多人遇到问题。这是一个相当大的问题。我想我一定遗漏了一些相当明显的东西。

我可以看到它尝试创建项目后，工作区中项目的目录结构看起来是正确的，但几乎所有文件都丢失了，包括 project.properties，这似乎与我的问题有关' m 基于错误日志(如下)。

我做了以下事情:

1. 首先，我尝试更新 eclipse 和 ADT。运气不好
2. 我尝试在新工作区中创建项目
3. 我删除并重新下载了 ADT 包
4. 我删除并重新安装了 JDK 7(按照 oracle 的卸载说明)

单击完成使用新的 android 应用程序向导后，我收到以下错误消息:

Errors occurred during the build.
Errors running builder 'Android Resource Manager' on project 'test'.
java.lang.NullPointerException

错误日志看起来像这样(我想包括一个屏幕截图，但该网站不允许我这样做，因为我是新用户。相反，我按照它们在我的页面中出现的顺序复制和粘贴消息日志(从最近到最近):

Errors occurred during the build.
    Errors running builder 'Android Resource Manager' on project 'test'.
Failed to load properties file for project 'test'
Failed to load properties file for project 'test'
Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".
Failed to load properties file for project 'test'
[No message for this one, but stack trace is for an InvocationTargetException]
Failed to load properties file for project 'test'
Failed to load properties file for project 'test'

最后，这里是 NPE 和 InvocationTargetException 的堆栈跟踪。

这是我关于 stackoverflow 的第一个问题。请让我知道如何改进它。我正在使用 eclipse 版本 22.6.2-1085508 和

 java version 1.7.0_60

Answer 1

好吧，因为我无法解决这个问题，所以我已经切换到 Android Studio 并且那里没有任何问题，但是当我最近买了一台新电脑时，我想我可以回到 ADT 包而不用问题。错误的。我有完全相同的问题。

我不明白为什么，但是卸载jdk1.7.0_60.jdk“解决”了这个问题。我从其他一些问题的答案中得到了尝试这个的想法(不幸的是，我无法再次找到它们进行链接)。在任何情况下，我都没有找到解释为什么这样做的原因，也没有找到关于如何在不卸载我的 JDK(我需要的)的情况下实现它的任何建议。任何能引导我朝着正确方向找出原因的答案或提示都将不胜感激。否则，我想我会提出一个新问题。

更新

我已经重新安装了 jdk，似乎没有问题。
