在Android Studio中构建项目时，Gradle会给出NullPointerException

有人可能会帮我修复这个Gradle（2.14.1）NullPointerException错误，该错误在我的Android Studio（2.2）崩溃后开始弹出。我是新手，所以我不知道如何处理这个问题。在Android Studio中构建项目时，Gradle会给出NullPointerException

我已经试过：

  • 清洁项目
  • 重新安装的Android Studio和SDK
  • 更新JRE（8u101）

，我不知道还有什么试图解决这个问题。

这是--stacktrace--debug在gradle控制台中的错误：

在app'build中使用最新的'2.2.0' gradle构建工具。 gradle'文件。 – Piyush

你有构建异常你错过任何依赖？ – DevKRos

当我安装Android Studio 2.2时，它促使我将gradle更新到2.2.0，并且我接受了。它工作正常，直到Android Studio崩溃。在我的'build.gradle'里面写着2.2.0，但在我的'C：\ Program Files \ Android \ Android Studio \ gradle'目录中只有2.14.1。我认为这个依赖在某处变得腐败。我如何强制它重新更新到2.2.0？ – inferKNOX

没有我试过在Android Studio/SDK方面工作。所以我不得不做手动路线。我：

  • 去了AndroidStudioProjects目录并手动更改了名称（刚添加“-backup”到目录名结尾）;
  • 使用原始项目名称和包名称在Android Studio中创建了一个新项目，然后关闭了Android Studio;
  • 返回到AndroidStudioProjects目录，并将备份[project]\app\build.gradle文件中的依赖项部分复制到新项目中的同一文件;
  • 复制了[project]\app\src\main目录，其中的所有内容都从旧项目复制到新项目;
  • 已打开Android Studio并已选中Build > Rebuild Project
  • 然后刚刚运行该项目并运行。

现在开始修复VCS ... -_-！

确保如果您有local.properties，则sdk.dir和ndk.dir（如果已定义）的路径实际存在。在我的情况下，我的项目没有使用ndk，但是我的local.properties是从一个项目中拷贝过来的，而ndk目录是无效的。我不认为这会起作用，但我下载并提取了ndk到local.properties中的路径，现在它工作。我想我可以轻松地在local.properties中注释/删除该行，但那不会很有趣.. :)
