无法在Android Studio中构建项目

I am trying to import a project in Android Studio. This code supposedly works but I cannot seem to be able to build the project. This is the error that is produced when I am trying to build:

我正在Android Studio中导入一个项目。这段代码可能有效，但我似乎无法构建这个项目。这是我在尝试构建时产生的错误:

Error:Execution failed for task ':openCVLibrary2410:compileReleaseJava'.

错误:任务':openCVLibrary2410: compiler ereleasejava '执行失败。

Cannot find System Java Compiler. Ensure that you have installed a JDK (not just a JRE) and configured your JAVA_HOME system variable to point to the according directory.

无法找到系统Java编译器。确保您安装了JDK(而不仅仅是JRE)并将JAVA_HOME系统变量配置为指向相应目录。

I have searched for a solution, but what I found was was either referring to eclipse or changing the jdk position for

我搜索了一个解决方案，但是我发现要么是指eclipse，要么是改变jdk的位置

File > other Settings > Default Project Structure

Which is not a valid solution for me because I checked my previous Android Studio Projects and all have the same position

哪个方案对我来说不是一个有效的解决方案，因为我检查了之前的Android Studio项目，结果都是一样的

This is the stacktrace:

While I was posting here the gradle files my eye caught something. I changed the build tools version from 'com.android.tools.build:gradle:1.1.0' to 'com.android.tools.build:gradle:2.2.2'and now it is building as it should

当我在这里发布等级文件时，我的眼睛发现了一些东西。我将构建工具的版本从“com.android.tools.build:gradle:1.1.0”改为“com.android.tools.build:gradle:2.2.2”，现在它正在按照它的需要构建。
