Android Studio和gradle

我尝试在androidstudio中导入Xabber（GitHub），我做了git初始化等。 现在我发现我可以为这个问题启动应用程序Gradle，我到处都找过了，但找不到任何有效的

问题是：

Error:Execution failed for task ':app:dexBetaDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1

谢谢

所以我在这里找到了解决方案

诀窍是在Java库模块的build.gradle文件中，您需要包含以下内容

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

看看这个

按如下方式编辑你的

app/build.gradle

文件：

model {
    android {
        ...
    }
    ...
    compileOptions.with {
        sourceCompatibility = JavaVersion.VERSION_1_7
        targetCompatibility = JavaVersion.VERSION_1_7
    }
}

---

在模块文件的build.gradle中，注释掉“targetCompatibility JavaVersion.VERSION_1_7”行

---

因为错误日志说“建议的解决方案是使用最新的编译器从源代码重新编译类，而不指定任何“-target”类型选项。”

像这样？？存储库{mavenCentral（）}应用插件：“java库分发”依赖项{compile'org.bouncycastle:bcprov-jdk15on:1.49'testCompile'junit:junit:4.11'testCompile'org.mockito:mockito all:1.9.5'testCompile'org.apache.commons:commons-lang3:3.3.2'}编译选项{应用插件：“java”sourceCompatibility=1.6 targetCompatibility=1.6}
