Dagger 2与Android数据绑定冲突

概述将 Dagger 2和 Android Data Binding添加到我的项目时,我得到一些下面的构建时错误.这似乎是一个已知问题(见 [1]或 [2]),因为我得到完全相同的错误.不幸的是我无法解决它们(就像其他人一样).有人对当前版本的Dagger 2和数据绑定有完整的工作设置,可以提供帮助吗？ 这里的错误： C:\Users\Kai\AndroidStudioProjects\WearCo 将 Dagger 2和 Android Data Binding添加到我的项目时,我得到一些下面的构建时错误.这似乎是一个已知问题(见 [1]或 [2]),因为我得到完全相同的错误.不幸的是我无法解决它们(就像其他人一样).有人对当前版本的Dagger 2和数据绑定有完整的工作设置,可以提供帮助吗？

这里的错误：

我的项目build.gradle：

// top-level build file where you can add configuration options common to all sub-projects/modules.buildscript {    repositorIEs {        jcenter()    }    dependencIEs {        classpath 'com.androID.tools.build:gradle:2.1.2'        classpath 'com.neenbedankt.gradle.plugins:androID-apt:1.8'        // NOTE: Do not place your application dependencIEs here; they belong        // in the indivIDual module build.gradle files    }}allprojects {    repositorIEs {        jcenter()    }}task clean(type: Delete) {    delete rootProject.buildDir}

应用程序build.gradle：

apply plugin: 'com.androID.application'apply plugin: 'com.neenbedankt.androID-apt'androID {    compileSdkVersion 24    buildToolsversion "23.0.3"    dataBinding {        enabled = true    }    defaultConfig {        applicationID "com.comparilla.wearcompass"        minSdkVersion 21        targetSdkVersion 24        versionCode 1        versionname "1.0"    }    buildTypes {        release {            MinifyEnabled false            proguardfiles getDefaultProguardfile('proguard-androID.txt'),'proguard-rules.pro'        }    }}dependencIEs {    compile filetree(include: ['*.jar'],dir: 'libs')    wearapp project(':wear')    testCompile 'junit:junit:4.12'    // to enable BuildConfig.DEBUG in the common library    // see https://stackoverflow.com/a/29163361/166229    releaseCompile project(path: ':common',configuration: 'release')    deBUGCompile project(path: ':common',configuration: 'deBUG')    compile 'com.androID.support:appcompat-v7:24.0.0'    compile 'com.Google.androID.gms:play-services-maps:9.0.2'    compile 'com.androID.support:design:24.0.0'    compile 'com.androID.support:preference-v14:24.0.0'    compile 'com.Google.dagger:dagger:2.5'    apt 'com.Google.dagger:dagger-compiler:2.5'    provIDed 'javax.annotation:Jsr250-API:1.0'}

我也尝试在apt’com.Google.dagger：dagger-compiler：2.5’中提供而不是apt,但没有成功.同时注释掉apply plugin：’com.neenbedankt.androID-apt’没有帮助(就像提供的资源中所建议的那样).

解决方法 我确实在同一个项目中配置了Dagger 2和DataBinding,它没有任何问题.

您在Dagger 2配置中确实有错误.您尝试注入的headingService无法创建,因为您没有为它提供@ProvIDes注释,并且该类在构造函数上没有@Inject注释.
