更改Android versionCode会导致build.gradle错误

Question

I just upgraded my Android Studio to 1.4.1.

In build.gradle , When i change my versionCode ,

import org.apache.commons.lang3.JavaVersion

gets added to the top of build.gradle , which causes the error:

build file '/../app/build.gradle': 1: unable to resolve class org.apache.commons.lang3.JavaVersion
 @ line 1, column 1.
   import org.apache.commons.lang3.JavaVersion

When I remove the line import org.apache.commons.lang3.JavaVersion , it gets added back automatically after a while.

When I revert the versionCode back to 1, the import statement disappears and all is well.

Gradle File

import org.apache.commons.lang3.JavaVersion

apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.0"

    defaultConfig {
        applicationId "com.x.app"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 2
        versionName "1.0.1"
        renderscriptTargetApi 19
        renderscriptSupportModeEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    packagingOptions {
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/LICENSE.txt'
    }
}

How do i solve this issue?

Thanks!

Answer 1

Simply remove the import.

Your versionCode line in build.gradle should look like this :

versionCode 3

Answer 2

You use this class on compileOptions. That has nothing to do with pour versionCode, which is just fine.

Java 8 is not supported in Android, so I guess your problem is here
