Hi, all. When I try to build my project (it's very early in development, not quite ready for an MVP) I get errors like this (pulled from the overall stack trace):

* What went wrong:
A problem occurred configuring root project 'variant'.
> Could not resolve all artifacts for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:8.5.0.
     Required by:

         project : > com.android.library:com.android.library.gradle.plugin:8.5.0

But the project can build and run well from Android Studio. What can I do to fix the build so that things like SonarQube can publish realistic code status?

My project's repo is here if anybody would like to look at things: https://github.com/comixed/variant/

Hey there, what exactly do you mean by When I try to build my project (it's very early in development, not quite ready for an MVP) I get errors like this (pulled from the overall stack trace) ? Do you mean by command line, in a build step? What build command did you use? Have you used the gradle task list in the side bar?
I had no issues with building your project. Tried the ./gradlew build command and some builds from the command line. aside from some warnings, there was no issue with any outputs.
Other things to check:
• ./gradlew build --info to get better output
• java -version check if this statements nets the same result as in the sdk dropdown

[Darryl Pierce]

I'm trying to build from the command line:

./gradlew clean build check sonar --info

[Darryl Pierce]

I just did:

./gradlew build --info

and I see the same output:

The logs indicate you're using java 8 on the commandline
1. com.android.tools.build:gradle:8.5.0 requires Java 11
2. app.cash.sqldelight:gradle-plugin:2.0.2 requires Java 17
3. org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:4.4.1.3373 requires Java 11

[Darryl Pierce]

Interesting: the box I'm using has JDK8, 11, 17, and 21 on it, but defaults to 8. When I switched to 11 it didn't fail when I ran "./gradlew build --info"

[Darryl Pierce]

How does that affect that the project uses:

jvmTarget = "1.8"

in the gradle build files?

[Matthias Reither]

1. This only specifies the byte code version that the Kotlin compiler should generate when compiling your Kotlin code. This is about the output of the compilation process, not the Java version running the build itself. The effects are that the bytecode is compatible with Java 8 JVMs. So it should not affect much all in a KMP-Project targeting iOS and android. The only thing is that you won't be able to use Java language features from versions higher than 8 in your generated bytecode.
