react-native: [Resolved] Release build fails with Hermes and RN 0.61.4 on mac

I am facing same issue.

See screenshot attached. I am facing it in release build only. In both versions i.e. react-native 0.61.3 and 0.61.4.

sorry for a big file but there is a lot more but I skip it. @holospeed I’m using react native 61.5 version

if you don’t have duplication, than:

• in terminal go to your android folder in the project (cd android)
• run: ./gradlew clean
• go back to the project directory (cd …)
• if you have not added jetifier to your project add it (for example: yarn add jetifier)
• run: npx jetify in the project directory
• go to android folder (cd android)
• run: ./gradlew bundleRelease

build bundleRelease success but fail to install, and still react-native run-android --variant=release… fails

Property duplication caused my issue! There was a property multiple times in my code! After the fix it has been built successfully!

THANK YOU @yusufsal !!!
