The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher.

Describe the bug I can't upgrade my gradle version because i got:

FAILURE: Build failed with an exception.

* What went wrong:
The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher.
The following dependencies do not satisfy the required version:
project ':bluetooth_thermal_printer' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

If I compile with a less recent version of gradle I get:

w: Some runtime JAR files in the classpath have an incompatible version. Consider removing them from the classpath

For now it works, but may be not i future. Can you solve the issue?

Many thanks, Claudio Driussi

Was this issue solved. I have opted to use blue_thermal_printer ^1.2.3

Remember to refactor your build.gradle (Module: bluetooth_thermal_printer). The error probably arises from there.

Yes, I will try. But I solved with flutter_bluetooth_printer which raises a warning, but has all java source code so will be recompiled with the flutter app.

Had the same issue, I updated this part of my build.gradle to solve the error. dependencies { classpath 'com.android.tools.build:gradle:7.2.0' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } Before i had dependencies { classpath 'com.android.tools.build:gradle:7.3.0' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } Somehow changing from gradle:7.3.0 to gradle:7.2.0 fixes the issue if you already have ext.kotlin_version > '1.5.20'

Use the following with the latest gradle:

bluetooth_thermal_printer: git: url: https://github.com/Rajath4/BluetoothThermalPrinter ref: 7abaebaf191b9dee8399f72ea4777c95cc5e194c
