1、app:transformClassesWithJarMergingForDebug‘.
Error:Execution failed for task ‘:app:transformClassesWithJarMergingForDebug‘. > com.android.build.transform.api.TransformException: java.util.zip.ZipException: duplicate entry: > android/support/v7/cardview/BuildConfig.class
解决办法:

2、Error:Unable to resolve dependency for ‘:app@releaseUnitTest/compileClasspath‘: Could not download junit.jar (junit:junit:4.12)
<a href="openFile:/Users/shenjiaqi/Documents/sjq/annotation/app/build.gradle">Open File</a><br><a href="Unable to resolve dependency for ':app@releaseUnitTest/compileClasspath': Could not download junit.jar (junit:junit:4.12)">Show Details</a>
解决办法:确保在 app 的 build.gradle 中包含下面语句:
repositories { google() jcenter() maven {url ‘https://jitpark.io/‘} }
完整版如下:
apply plugin: ‘com.android.application‘ android { compileSdkVersion 27 buildToolsVersion ‘26.0.2‘ defaultConfig { applicationId "com.sjq.recycletest" minSdkVersion 15 targetSdkVersion 27 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘ } } repositories { google() jcenter() } sourceSets { main { manifest.srcFile ‘src/main/AndroidManifest.xml‘ java.srcDirs = [‘src/main/java‘, ‘src/main/aidl‘] resources.srcDirs = [‘src/main/java‘, ‘src/main/aidl‘] aidl.srcDirs = [‘src/main/aidl‘] res.srcDirs = [‘src/main/res‘] assets.srcDirs = [‘src/main/assets‘] } } } dependencies { compile fileTree(include: [‘*.jar‘], dir: ‘libs‘) androidTestCompile(‘com.android.support.test.espresso:espresso-core:2.2.2‘, { exclude group: ‘com.android.support‘, module: ‘support-annotations‘ }) implementation ‘com.android.support:appcompat-v7:27.1.1‘ implementation ‘com.android.support:recyclerview-v7:27.1.1‘ testImplementation ‘junit:junit:4.12‘ }
3、注解报错Annotation processors must be explicitly declared now.
解决办法:
在app的build中
android { ... defaultConfig { ... //添加如下配置就OK了 javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } } } ... }
