you can simplify this by using the following:
./gradlew kotlin-mcp-client:build kotlin-mcp-server:build weather-stdio-server:build

gradle.properties

 kotlin.code.style=official
 kotlin.daemon.jvmargs=-Xmx4G
+# Build JS targets using npm package manager https://kotlinlang.org/docs/js-project-setup.html#npm-dependencies
+kotlin.js.yarn=false


You can also work with npm dependencies directly using the npm package manager instead.

Do we want to use npm directly?

No, it's Kotlin doing this for us. Or it will require Yarn to be installed. I just don't have Yarn on my fresh laptop ;)

Then we should remove this property, if I understood the documentation correctly.

Changes: - The return type of `ASTHelpers.asFlagSet` has changed. The previous type was `EnumSet<Flags.Flag>`, where `Flags.Flag` is an enum in the javac class `Flags`. A recent JDK change has replaced that enum with a new top-level enum called `FlagsEnum`. It is not possible to change `ASTHelpers.asFlagSet` in a way that would be type-safe and compatible with the enums from JDKs both before and after the change. Instead, the method now returns `ImmutableSet<String>`, where the strings come from the `toString()` of the enum constants. That means they are `"native"`, `"abstract"`, etc. - Flag `IO.print[ln]()` in [`SystemOut`](https://errorprone.info/bugpattern/SystemOut).
