mvn clean package

it raise error: Failed to execute goal com.github.wvengen:proguard-maven-plugin:2.3.1:proguard (default) on project api: Obfuscation failed (result=1) → [Help 1]. Does anything need be installed more? Thanks all. have a nice day!

my pom:

Hi @test_dev,

Welcome! After examination, it appears it is not our plugin where the issue occurs, so we would advise opening this issue on the plugin’s Github page. We don’t officially provide a Maven integration or support but that should be a good first step for you.

Thanks for your time here and let us know how it goes,
Jesse

Hi Jesse ,

Do you provide support for gradle ?

Hi @Waheed_Khan,

For non-Android yes: e.g. here’s an example application that uses Gradle https://github.com/Guardsquare/proguard/tree/master/examples/application

For Android: ProGuard no longer supports AGP since AGP 8.

I hope this helps and have a great day!

Thanks Jesse your answer is helpful. I have one more query. Do proguard supports spring boot project that uses maven ? or gradle with spring boot ? if yes then then how as spring uses reflection too much. As I have done some R&D on this.

Its not going to work with spring based applications as these apps use reflection too much.

I have also put a question on this. If you could guide me that will be very helpful.
