在模組化開發時需要在各個模組的build.gradle裡都要配置

defaultConfig {
        ...

        javaCompileOptions {
            annotationProcessorOptions {
                arguments = [moduleName: project.getName()]
            }
        }

    }


dependencies {
    ...

    annotationProcessor 'com.alibaba:arouter-compiler:1.1.4'
    implementation project(':base')//base模組裡新增依賴

}
 

同時base模組裡

dependencies {
   ...
    compile ('com.alibaba:arouter-api:1.3.1'){ exclude group: 'com.android.support' }
//    implementation 'com.alibaba:arouter-api:1.3.1'

}

注意：匯入arouter-api時可能出現V4包版本不一致，如下異常，所以將其遮蔽

Error:Execution failed for task ':app:preDebugBuild'.
> Android dependency 'com.android.support:support-v4' has different version for the compile (25.2.0) and runtime (27.1.1) classpath. You should manually set the same version via DependencyResolution
 

雖然編譯沒有問題，但是在執行時可能出現異常

com.android.build.api.transform.TransformException: com.android.dex.DexException: Multiple dex files define Lcom/alibaba/android/arouter/routes/ARouter$$Group$$user;
