Is there a way to change the gradle.properties file in Unity

Question

Unity has a default gradle.properties file that gets added during the build process. While its possible to change the build.gradle and the settings.gradle files as mentioned here https://docs.unity3d.com/Manual/android-gradle-overview.html there is no mention of being able to change gradle.properties within the unity docs. The file also gets recreated every build attempt so editing it within the temp/gradleOut after a build and building again doesn't work. I know exporting the project is possible as well, but I'm looking for a solution where the project can be run directly from unity.

Btw this question is NOT a duplicate of this question How to use Gradle in Unity The answer here has nothing to do with modifying the gradle.properties file.

This is a duplicate of this question that got incorrectly marked as a duplicate how to change default gradle.properties of Unity?

Answer 1

Maybe my answer is a bit outdated but in Unity 2020 you can do it in:

Player Settings -> Tab Android (with robot obviously) -> Publishing Settings -> Custom Gradle Properties Template (checkbox).

After enabling the checkbox you will see the path to gradleTemplate.properties (usually it appears in Assets/Plugins/Android directory) file which will be merged with final gradle.properties.

Everything you need you can write to the end of file after **ADDITIONAL_PROPERTIES** string.

Example:

org.gradle.jvmargs=-Xmx**JVM_HEAP_SIZE**M
org.gradle.parallel=true
android.enableR8=**MINIFY_WITH_R_EIGHT**
**ADDITIONAL_PROPERTIES**

android.useAndroidX = true // I added this property to fix error:  This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry.
