java error after upgrading android-sdk version

Question

I was updating our gradle app from Android SDK 23 to 24 (25 doesn't work either) and am getting the following error.

Execution failed for task  :app:transformClassesWithMultidexlistForGoogleRelease'.
com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\android\jdk\bin\java.exe'' finished with non-zero exit value 1

I tried building both 24 and 25, with every variant of the build tools I could find and they all produce this error. Most of the cases I saw online by this error were solved by building clean or adding multidex, which we already use.

I have also tried changing the java max heap size.

Any ideas on how to get through this, or figure out what is actually going on?
