Error during the build on Android Studio with @capacitor/barcode-scanner

Capacitor
1

Hello,

I don’t arrive to build/run the application on Android Studio because of the barcode-scanner package (version 1.0.2 or 1.0.4… not tried on 2.0.x).
Here is the error message I get:

Execution failed for task ':capacitor-barcode-scanner:compileDebugKotlin'.
> Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (17) and 'compileDebugKotlin' (21).

1. What is it?
2. Can I solve it without upgrading to Capacitor V7 for the moment?

Thanks for your help,
Loïc

To confirm, you set minSdkVersion = 26 (reference)?

What version of Android Studio and what OS (Windows, Linux, Mac) are you running?

In Android Studio, if you go to File → Settings → Build, Execution, Deployment → Build Tools → Gradle, what is the Gradle JDK set to?

Hi @twestrick,

Thanks for your reply :slight_smile:

Yes, minSdkVersion = 26. (and the other settings defined in the documentation are the same too)

I use Android Studio Ladybug Feature Drop | 2024.2.2 on MacOs.

Here are the Gradle JDK settings:

Is there something wrong?

I would try JDK v17. I had similar problems when I upgraded to Ladybug in my Capacitor 6 app since Ladybug now defaults to v21.

To downgrade, you have to download v17 via that interface. Make sure it is in a different location than v21. It didn’t work for me in the same location.

Also, after changing the version I had to restart my computer to have it take affect as the Gradle Daemon was caching v21.

Hi Tom,

Many thanks for your help, it works fine after downgrading to v17 :slight_smile:

Have a nice day,
