Description
I am using Kotlin 1.9.20 with Gradle 8.4 with id("com.google.devtools.ksp") version "1.9.20-1.0.14" in a gradle multimodule project and I am unable to build the project. Getting the errors below:
**What went wrong:**
```
Some problems were found with the configuration of task ':xxxxx:kspKotlin' (type 'KspTaskJvm').
Gradle detected a problem with the following location: 'C:\Users...\ServiceGrpc.java'.
Reason: Task ':xxxxx-rest:kspKotlin' uses this output of task ':xxxxx-rest:generateProto' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
Possible solutions:
Declare task ':xxxxx-rest:generateProto' as an input of ':xxxxx-rest:kspKotlin'.
Declare an explicit dependency on ':xxxxx-rest:generateProto' from ':xxxxx-rest:kspKotlin' using Task#dependsOn.
Declare an explicit dependency on ':xxxxx-rest:generateProto' from ':xxxxx-rest:kspKotlin' using Task#mustRunAfte
r.
```
When setting explicit dependency as suggest, gradle is unable to find the task kspKotlin.
Thanks

Research direction
Start by reproducing the reported configuration with Kotlin 1.9.20, Gradle 8.4, KSP 1.9.20-1.0.14, and the tasks :xxxxx-rest:generateProto and :xxxxx-rest:kspKotlin. Trace how the plugin wires generated ServiceGrpc.java into KSP, then verify that a clean build succeeds without a manual task dependency.
