No

Reproduction steps

We are using a proprietary tool called DexGuard in our build process - this is a "variant" of ProGuard.

The latest release 1.3.0 of the exoplayer artifact contains an invalid ProGuard rule which was introduced here: 97b8f1a

The official ProGuard playground also marks this rule as invalid: https://playground.proguard.com/p/4usJIa

Expected result

The app can be built successfully with DexGuard

Actual result

Build fails with the following exception:

com.guardsquare.dexguard.cuB: Expecting type and name instead of just 'build' before '(' in line 14819 of file '/some/path/app/build/outputs/dexguard/configs/<redacted>/prerelease/consumer-rules.pro'from package 'androidx.media3',
