Error when included in project with butterknife

[RoryKelly]

in an app I'm slowly moving over to kotlin in Build.gradle I add in:

 kapt 'com.jakewharton:butterknife-compiler:8.5.1'
  compile 'com.jakewharton:butterknife:8.5.1'
  compile 'com.jakewharton:kotterknife:0.1.0-SNAPSHOT'

When I Build it fails with:

Error:Error converting bytecode to dex:

same here but with:

compile 'com.jakewharton:butterknife:8.6.0'
compile 'com.jakewharton:kotterknife:0.1.0-SNAPSHOT'

I have the same problem with @RoryKelly

really need help

[CodyEngel]

The error is saying that there are multiple inclusions of Butterknife. Have either of you tried removing butterknife from the dependency?

[RoryKelly]

Yes Removing the butterknife dependency fixes the issue. Though if you have a large project and want to migrate to kotterknife it would be very useful to be able to use both simultaneously.

I have embedded the kotlin file in my project for now.

[Evanuke]

Is there any chance to avoid this problem? I got exact same error. I want to use 3rd party library, based on Java, which use Butterknife, but I already use in my project Kotterknife because it's fully written in Kotlin :(

[CodyEngel]

I would file an issue with the library that uses ButterKnife or just not use a library that forces you use ButterKnife. It's a terrible idea on the authors part to include a library like that for their own library.
