Question

这是我的gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "25.0.2"

    dexOptions {
        incremental = true;
        preDexLibraries = false
        javaMaxHeapSize "4g" // 2g should be also OK
    }


    defaultConfig {
        applicationId "com.example.pc.myapplication"
        minSdkVersion 23
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

当我创建一个android项目时。打算用手机运行它，我遇到了问题

Error:Execution failed for task ':app:dexDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_17\bin\java.exe'' finished with non-zero exit value 1

昨天，我遇到了类似的问题，它由于添加了多个jar。通过删除jar可以解决，但今天我不在项目中添加jar。

将minSDK版本更改为16后，上面是完整的堆栈跟踪。

我搜索过类似的问题，可能是项目结构编译sdk版本和Build工具版本不同于gradle设置但解决方案对我不起作用。

Answer 1

尝试清理项目并重建。这应该可以解决这个问题。

如果仍然存在，请尝试删除以下代码行：

dexOptions { incremental = true; preDexLibraries = false javaMaxHeapSize "4g" // 2g should be also OK }

将minSdkVersion 23更改为16并尝试清理并重建项目

错误：任务'：app：dexDebug'，org.gradle.process.internal.ExecException的执行失败
