After switching to Java 8 (below are the newly added lines) for our Android project, Gradle build always gets stuck at :app:transformClassesWithDexBuilderForDebug.

compileOptions {
    sourceCompatibility 1.8
    targetCompatibility 1.8
}

Please suggest how to reduce this build time. Before adding the above lines it was around 3 minutes most. Our gradle plugin version is 3.1.2 It takes even more than 30 minutes for every first build, after clean build / branch change / Android Studio restart

did you tried invalidate cache and restart? – karan Jan 30 '19 at 12:48
@KaranMer yep, didn't help. – Rivu Chakraborty Jan 30 '19 at 14:52
There's nothing to go on here. I recommend you do a `--scan`. – weston Jan 30 '19 at 14:58
Have you tried using the latest version of the Android Gradle Plugin? `3.3.0`? – Nelson Osacky Jan 30 '19 at 15:00
@weston as suggested by you, I did a --scan, and as I said, `:app:transformClassesWithDexBuilderForDebug` takes most of the time, 37 minutes 34 seconds out of 42 minutes 22 seconds total build time. – Rivu Chakraborty Jan 31 '19 at 06:06
@NelsonOsacky no, we were having some other issues when tried to upgrade to gradle 3.3, so decided to postpone it to after the current sprint. – Rivu Chakraborty Jan 31 '19 at 06:07
There's a lot more to a scan than timing. Look at the suggestions and memory usage for example. Share the scan url if you are comfortable. Share on asg if you like. – weston Jan 31 '19 at 12:19
@weston couldn't find you in asg with Weston, posted the url as a reply to my post in ASG. Please help out. – Rivu Chakraborty Jan 31 '19 at 12:27
