1. 旧项目 AndroidStudio3.4 编译正常

   classpath 'com.android.tools.build:gradle:3.4.2'

   gradle/wrapper/gradle-wrapper.properties
   distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

2. 升级到 AndroidStudio3.5 编译报错

   classpath 'com.android.tools.build:gradle:3.5.2'

   gradle/wrapper/gradle-wrapper.properties

   distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

   1. FAILURE: Build failed with an exception.

   2.  

   3. * What went wrong:

   4. Execution failed for task ':EasyAndroid:javaPreCompileDebug'.

   5. > Could not resolve all files for configuration ':EasyAndroid:debugCompileClasspath'.

   6. > Failed to transform artifact 'leakcanary-android-1.5.4.aar (:leakcanary-android-1.5.4:)' to match attributes {artifactType=android-classes, org.gradle.usage=java-api}.

   7. > Execution failed for AarToClassTransform: libs\leakcanary-android-1.5.4.aar.

   8. > duplicate entry: META-INF/MANIFEST.MF

最新结果：升级gradle到最新版 比如 3.5.4 即可：

1. dependencies {

2. // classpath 'com.android.tools.build:gradle:3.5.2'

3. // classpath 'com.android.tools.build:gradle:3.5.3'

4. classpath 'com.android.tools.build:gradle:3.5.4'

5. }
