Hey folks, I've hit a strange issue when upgrading my Android project to Gradle 8. I haven't been able to find the root of the issue but somehow it seems like some gradle tasks are using different java versions than other.
```Execution failed for task ':core:compileDebugKotlin'.
&gt; 'compileDebugJavaWithJavac' task (current target is 1.8) and 'compileDebugKotlin' task (current target is 17) jvm target compatibility should be set to the same Java version.```

Like, even if I add a new toolchain
```jvmToolchain {
        (this as JavaToolchainSpec).languageVersion.set(JavaLanguageVersion.of("11"))
    }```
I still get
```'compileDebugJavaWithJavac' task (current target is 1.8) and 'compileDebugKotlin' task (current target is 11) ```

Updating this seems to work, but I still need to keep the bytecode compatible with 1.8
```android {
compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
}```

I got this issue and made the change you did + I updated some other value that was set to 1.8 to 17.

AGP only since 8.1 version properly supports toolchains: <https://issuetracker.google.com/issues/260059413>
