我调查了一段时间,可能在这里看到了与aar和可传递依赖项有关的最受欢迎的答案,但是对于我来说,如何使它起作用仍然不清楚。
所以:
我有给定gradle配置的android库:
apply plugin: 'android-library' apply plugin: 'android-maven' version = "1.0.0" group = "com.somepackage" buildscript { repositories { mavenCentral() mavenLocal() } dependencies { classpath 'com.github.dcendents:android-maven-plugin:1.0' } } android { compileSdkVersion 19 buildToolsVersion '19.0.3' defaultConfig { minSdkVersion 10 } } repositories { maven { url 'http://www.bugsense.com/gradle/' } } dependencies { provided 'com.google.android.gms:play-services:+' provided 'com.android.support:appcompat-v7:+' compile 'com.google.code.gson:gson:2.2.4' compile 'com.bugsense.trace:bugsense:3.6' compile 'commons-net:commons-net:3.3' }
然后,我将其部署到本地Maven存储库gradle install。部署库的POM文件如下所示:
<?xml version="1.0" encoding="UTF-8"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <modelVersion>4.0.0</modelVersion> <groupId>com.sprezzat</groupId> <artifactId>app</artifactId> <version>1.0.0</version> <packaging>aar</packaging> <dependencies> <dependency> <groupId>com.bugsense.trace</groupId> <artifactId>bugsense</artifactId> <version>3.6</version> <scope>compile</scope> </dependency> <dependency> <groupId>commons-net</groupId> <artifactId>commons-net</artifactId> <version>3.3</version> <scope>compile</scope> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.2.4</version> <scope>compile</scope> </dependency> </dependencies> </project>
最后使用上述库作为依赖项对我的Android应用程序进行配置:
buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.9.+' } } apply plugin: 'android' repositories { mavenCentral() mavenLocal() } android { compileSdkVersion 15 buildToolsVersion "19.0.2" defaultConfig { minSdkVersion 10 targetSdkVersion 18 } } dependencies { compile 'com.google.android.gms:play-services:+' compile 'com.android.support:appcompat-v7:+' compile 'com.somepackage:LIBRARY_NAME:1.0.0@aar' }
在手机上部署应用程序后,我得到NoClassDefFoundError了属于我的Android库的编译依赖项的类。
NoClassDefFoundError
使用gradle dependencies以下命令检查我的android应用程序依赖项:
gradle dependencies
apk - Classpath packaged with the compiled main classes. +--- com.google.android.gms:play-services:+ -> 4.3.23 | \--- com.android.support:support-v4:19.0.1 -> 19.1.0 +--- com.android.support:appcompat-v7:+ -> 19.1.0 | \--- com.android.support:support-v4:19.1.0 \--- com.somepackage:LIBRARY_NAME:1.0.0
根据上面的树,没有检测到所有传递依赖。问题出在哪里,应如何正确解决?
我已经通过transitive为aar依赖项设置属性解决了我的问题:
transitive
compile ('com.somepackage:LIBRARY_NAME:1.0.0@aar'){ transitive=true }
