我的应用程序中不支持major.minor版本52.0 [英] Unsupported major.minor version 52.0 in my app

问题描述

我正在尝试编译我的Android项目而且我收到此错误

I'm trying to compile my Android project and I'm getting this error

[INFO] Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0

我一直在阅读其他帖子，试图用Java 8编译可能会导致错误，但不是我的情况，我有以下Java版本：

I've been reading in other post that try to compile with Java 8 might cause that error but not my case, I have the following Java version:

java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

操作系统：Linux Mint
（我没有安装Java 8.）
Build：MAVEN

OS: Linux Mint (I'm not have Java 8 installed.) Build: MAVEN

任何人都可以帮我吗？

推荐答案

我面对这个职业选手从android studio制作新项目时也有瑕疵。

I face this problem too when making new project from android studio.

我已经能够通过降低app gradle设置中的buildToolsVersion来解决这个问题：
change {module-name } /build.gradle line

I've been able to resolve this by downgrading buildToolsVersion in app gradle setting: change {module-name}/build.gradle line

buildToolsVersion24.0.0 rc1

buildToolsVersion "24.0.0 rc1"

到

buildToolsVersion23.0.3

buildToolsVersion "23.0.3"

@Edit：

在Android Studio 2.1中转到文件 - >项目结构 - >应用程序 - >构建工具版本。将其更改为23.0.3

@
In Android Studio 2.1 Go to File-> Project Structure->App -> Build Tool Version. Change it to 23.0.3

执行上述方法时，仅在使用Java版本7且由于某种原因不想升级到java 8时。

Do the method above, only when you are using java version 7 and for some reason do not want to upgrade to java 8 yet.
