Gradle builds really slow with a multi-project structure

Question

When building with gradle on a multi-project setup containing roughly 140 projects/libraries, the build time took 1 hour and 22 minutes. And i was using --parallel

Answer 1

According to this post.

Right now each project will pre-dex its dependencies on its own. This means 2 components depending on the same library will both run pre-dex on that library's classes.jar which is silly. We're looking at fixing this.
