android jackson gradle,NoClassDefFoundError使用Jackson 2.2.x在Android上与Gradle

对于我的

Android项目,我设置了Gradle with

Jackson 2.2.x如下：

// build.gradle

buildscript {

repositories {

mavenCentral()

}

dependencies {

classpath 'com.android.tools.build:gradle:0.6.+'

}

}

apply plugin: 'android'

repositories {

mavenCentral()

}

android {

compileSdkVersion 18

buildToolsVersion "18.1.0"

defaultConfig {

minSdkVersion 8

targetSdkVersion 18

}

}

dependencies {

compile 'com.android.support:appcompat-v7:18.0.0'

compile 'com.android.support:support-v4:18.0.0'

compile 'com.google.android.gms:play-services:3.1.36'

compile 'com.fasterxml.jackson.core:jackson-databind:2.2.+'

compile 'com.fasterxml.jackson.core:jackson-core:2.2.+'

compile 'com.fasterxml.jackson.core:jackson-annotations:2.2.+'

}

我只是在这里使用ObjectMapper：

import com.fasterxml.jackson.databind.ObjectMapper;

// ...

ObjectMapper objectMapper = new ObjectMapper();

try {

Content content = objectMapper.readValue(inputStream,Content.class);

} catch (IOException e) {

e.printStackTrace();

}

当我运行gradle installDebug并启动应用程序的相关部分崩溃：

java.lang.NoClassDefFoundError: com.fasterxml.jackson.databind.ObjectMapper

思考：

>我注意到,在build.gradle中定义了com.fasterxml.jackson.core的错误消息中提到了com.fasterxml.jackson ….有不匹配导致问题吗？

>我把这个依赖关系块暂时移动到android块中,因为我found other build.gradle configurations这样结构化了.不过似乎没有什么区别.
