Error converting bytecode to dex org/apache/commons/io/FileCleaner (Android Studio 3.0 Preview beta 2/3)

Question

Our project compiles, but I can't install it into simulator. I see other people reporting similar issues, but their solutions were to change the version number. For us, this works on other developer's machines but not mine. Is there some cache I should delete?

I have reinstalled Android Studio 3.0, deleted ~/.gradle, deleted .gradle folder inside project, restarted AS, clean folder...

Is there something specific about this being an Apache class that is the issue?

And here is the dependencies from gradle:

Answer 1

I've not been able to find the cause of this problem because non of my dependencies dependes on commons-io, but in my case I fixed it by using another commons-io module:

I replaced
compile 'org.apache.commons:commons-io:1.3.2'

with
compile 'commons-io:commons-io:2.5'

Answer 2

Still not sure on the real answer, but our project works for the people that went to Android Studio 3 beta 3, and then rolled back to beta 2. Myself who never had beta 3 is the one that is broken. We tried this on a other laptops and are confident that something in our project is broken for users on beta 2 who never had beta 3. Our solution will be to wait for the next Android Studio version.
