Gradle Plugin: Support isolated projects

[hfhbd]

• Replace findProperty with providers.gradleProperty
• Ideally, KGP adds more provider (and DomainCollection) APIs instead Observable/Lazy, ConfigurationAwareProvider...

Can you please reopen this issue? I still get two issues when using 2.0.20-1.0.25-SNAPSHOT:

• ksp/gradle-plugin/src/main/kotlin/com/google/devtools/ksp/gradle/KspSubplugin.kt

  Line 901 in 429f173

  it.name == selfTaskName

• ksp/gradle-plugin/src/main/kotlin/com/google/devtools/ksp/gradle/KspSubplugin.kt

  Line 349 in 429f173

  kspExtension.excludedSources.buildDependencies.getDependencies(null).map { it.name }

Basically, you can't fetch the tasks list from the dependencies: org.gradle.api.InvalidUserCodeException: Project ':foo' cannot access task dependencies directly if you use a multi module setup :foo that depends on :bar using implementation given a Kotlin/JVM project.

I tried to enable Isolated Project with KSP 2.0.2
Then, gradle shows warnings at following locations.

• ksp/gradle-plugin/src/main/kotlin/com/google/devtools/ksp/gradle/KspAATask.kt

  Line 194 in b1d4a98

  kspExtension.excludedSources.buildDependencies.getDependencies(null).map { it.name }

Did #2713 fix this? If so, would it be possible to do a release soon?

[solrudev]

I've tested the recently released 2.3.4 version containing #2713 together with Kotlin 2.3.0, and project isolation seems to be working without problems.

[hfhbd]

Yeah, I also tested it with a K/JVM project.
