我是android gradle中的新手。我在编译时遇到问题。我有2个独立的项目,一个是common_lib(Java lib),一个是TestApp(Android)。以下是项目结构:
common_lib: 只有一个名为Hello.java的简单类
public class Hello {
}
build.gardle:
apply plugin: 'java'
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
}
我编译common_lib并且编译成功然后我将common_lib.jar复制到TestApp \ libs项目
TestApp:
的AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.test.app" >
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
MainActivity:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
build.gardle:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.3'
}
}
apply plugin: 'com.android.application'
repositories {
jcenter()
}
android {
compileSdkVersion 15
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.test.app"
minSdkVersion 15
targetSdkVersion 15
versionCode 1
versionName "1.0"
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_6
targetCompatibility JavaVersion.VERSION_1_6
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
}
我的问题是当我编译TestApp项目时,我收到以下错误:
错误:Gradle:任务执行失败&#39;:app:preDexRelease&#39;。
com.android.ide.common.process.ProcessException:org.gradle.process.internal.ExecException:Process&#39;命令 &#39; C:\ Program Files \ Java \ jdk1.8.0_25 \ bin \ java.exe&#39;&#39;完成了 非零退出值1
如果从libs文件夹中删除common_lib.jar,我可以编译该项目。有什么问题?
答案 0 :(得分:0)
删除行compile fileTree(include: ['*.jar'], dir: 'libs')
并尝试清理构建
或强>
删除所有库jar文件
