坏的类文件的魔法或版本 [英] Bad class file magic or version

问题描述

我已经知道这个问题已经被问很多时候和答案，但我发现没有一个答案固定我的问题。

I already know that question has been already asked very often and answers, but no one of the answers i found fixed my problem.

这是错误：

该错误是坏的类文件魔术（cafebabe）或版本（0034.0000）。

我建造，并在同一天执行的应用程序没有问题很多次，但现在这个失败，每次与此消息。

I builded and execute the application without problems many times in the same day but now this fails everytime with this message.

项目SDK是 Android的API 19平台和项目水平 1.7 。

Project SDK is Android API 19 Platform and project level is 1.7.

CompileSDK是 19 和buildToolsVersion是 '20 .0.0。

CompileSDK is 19 and buildToolsVersion is '20.0.0'.

编译选项：

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7
}

和依赖我：

compile files('libs/bananaquery.jar')

---

该库是建立与SDK Android的API 19平台与项目级别 1.7 。

---

The library is build with SDK Android API 19 Platform with project level 1.7.

我的的.jar 文件里面库/ 文件夹。

我用的IntelliJ IDEA 14 preVIEW，它可能是什么原因呢？随着IntelliJ IDEA的13仍然停留在摇篮同步

I use IntelliJ IDEA 14 Preview, it could be the reason? With IntellIJ IDEA 13 it remains stuck at "Gradle sync"

编译的文件可能是无用的，因为我有编译文件树（导演：库，包括：['的* .jar']）太

推荐答案

好吧，是我不好。

在项目SDK部分，当你添加一个 Android SDK中您应该提供的Java SDK 和我所有的Android的软件开发工具包使用的的Java 8 作为SDK，因此创建一个类文件，即使项目水平是错误的版本 1.7 （我不知道为什么，我认为这一切都是通过项目级选取）。

In the Project SDK section, when you add an Android SDK you should provide the Java SDK and all my Android SDKs uses Java 8 as SDK so it create the class files with the wrong version even if the Project level is 1.7 (i don't know why, i supposed that everything was choosed by Project level).

现在我改变了SDK（即 Java版本1.x.0部分。）

Now i changed the SDK (the java version "1.x.0" part.)

和它看起来编译罚款。

and it seems to compile fine.

这是工作在今天之前是因为我的SDK是 1.8 ，而不是其原因 Android的API X

The reason that worked before today was because my SDK was 1.8 and not Android API x
