Okhttp: ProGuard and 4.0.1 OkHttp issue

[ouachman]

Hello,

I updated from 3.14.2 to 4.0.1 today.

With 4.0.1 I cannot make a release build because the build gets stuck in the ProGuard phase, "Optimizing (pass 1/5)". The whole process usually takes around 10 min, I stopped after 120 minutes as it was stuck there. Cleaned up everything, restarted Android Studio, same thing.
I reverted to 3.14.2 and build is successful again.

Any idea what could cause this issue?

Looking on Google, I found something similar a few months ago on Okio: https://github.com/square/okio/issues/516

I'm not the person to help, but to get full information out, what version of proguard are you using?

[ouachman]

I am using the one dependant on Android Gradle.
Running "./gradlew buildEnvironment" I can see it's version 6.0.3.

Other info found along the way:

• com.android.tools.build:gradle:3.4.2
• wrapper version 5.1.1

[ouachman]

FYI forcing the use of the latest ProGuard version (6.1.1) ends up with the ProGuard build phase failing with an ArrayIndexOutOfBoundsException error.

Does the section on ProGuard here help?

You may want to switch to R8, it fixes all those issues, else you need to report to Proguard I thought 6.1 fixed both issues but it seems they only fixed one.

[ouachman]

Ok thanks. I'll try to switch to R8 then, it sounds easy enough if I can trust the Android Studio docs :)

I also encountered this problem and can reproduce it. I can provide a simple reproduction project if needed. @swankjesse

Using okhttp 4 and ProGuard optimizations will never end in the Optimizing (pass 1/5) process.

Thanks!

After upgrading to ProGuard 6.2.0/6.1.1, it is fixed.
