Build error with a android project with 2 flavours

[hiworld75018]

Hi, I am trying to use aspects on an android project but build failed with the exception

Execution failed for task ':app:transformClassesWithExtractJarsForInternalDebug'.
Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformClassesWithExtractJarsForInternalDebug'.
at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:69)
...
Caused by: java.lang.RuntimeException: error

at com.android.build.gradle.internal.pipeline.TransformTask.computeNonIncTransformInput(TransformTask.java:246)

What I did to use aspectJX

• add an android library ("aspectjx") to the android studio project - to hold JoinPoint(s)
• add dependencies to this library: appCompat and 'org.aspectj:aspectjrt:1.8.9'
• add to settings.gradle: include ':app', ':aspectjx'
• add to project gradle:
  resolutionStrategy { cacheChangingModulesFor 0, 'seconds' }
  dependencies {... classpath 'com.hujiang.aspectjx:gradle-android-plugin-aspectjx:1.0.9'}
• add to app grade:
  apply plugin: 'android-aspectjx'
  aspectjx { includeJarFilter 'android.context' excludeJarFilter '.jar' }
  dependencies {
  ...
  compile 'org.aspectj:aspectjtools:1.8.9'
  compile project ':aspectjx'
  }

My objective is to add a join point in android.context.Context.

Note: my app has 2 "flavors" (public and internal), hence the "transform...InternalDebug", and no join point has been defined yet.

Did I miss something ?
Thanks

Execution failed for task ':app:transformClassesWithExtractJarsForInternalDebug' occurs when two or more java class files conflict. your project dependencies the library(aspectjx) and the jar(com.hujiang.aspectjx:gradle-android-plugin-aspectjx:1.0.9) at the same time, it is the reason.

I am not sure to understand:

1. the project declares the classpath to the plugin library (gradle-android-plugin-aspectjx),
2. the custom android library "aspectjx" contains an @aspect public class and a LibrarySDK class (like the AspectJ demo) and depends on appcompat and aspectjrt libraries,
3. the app has 2 dependencies (aspectjtools and the "aspectjx" android library), and triggers the plugin at build time.

I can't see where two or more classes conflict... The gradle console gives me this log before failing:

• What went wrong:
  Execution failed for task ':app:transformClassesWithExtractJarsForInternalDebug'.

To get around the problem, is there any way to restrict code weaving to a few classes, using IncludeJarFilter and ExcludeJarFilter ?
