错误的Ja​​va编译器。包含一个Java模块作为依赖于Android的工作室 [英] Wrong Java Compiler When Including a Java Module as Dependency in Android Studio

问题描述

我有一个Java模块在我的Andr​​oid Studio项目就是一个Android模块的依赖性。我有以下异常出现在构建问题。

I have a java module in my Android Studio project that is a dependency of an Android module. I am having problems on build with the following exception appearing.

Error:Execution failed for task ':myApplication:preDexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:

一些阅读，我可以看到，这是值得做的Java编译器的Andr​​oid工作室使用后。但是我看不到的方式来改变其使用的编译器。

After some reading I can see that it is something to do with the Java compiler Android Studio is using. However I cannot see a way to change which compiler it uses.

Java的模块，我想在我的Andr​​oid模块包括一个我创建了采用Android Studio中去文件>新建模块> Java模块，所以我看不出有任何的选择，我会做出不同？

The Java module I am trying to include in my Android module is one I created using Android Studio by going File > New Module > Java Module so I can't see any option I could make different?

任何想法将是巨大的。

推荐答案

所以，我已经找到了解决方案，在这个的博客文章。

So I have found the solution at this blog post.

诀窍就是在你的Java库模块的build.gradle文件，你需要包括以下内容。

The trick is in your Java Library module's build.gradle file you need to include the following.

apply plugin: 'java'
sourceCompatibility = 1.6
targetCompatibility = 1.6

这将然后工作。
