2024年の春、昨日開催されたJJUG CCC 2024 Spring に参加してきました！家庭の事情で午後からの参加となりましたが、Javaコミュニティの熱気を肌で感じながら、最新技術の情報や多くの開発者との交流を楽しむことができました。この記事では、キーノート、ブースでの会話、懇親会、そしてアンカンファレンスの様子をレポートします。
e: org.jetbrains.kotlin.konan.MissingXcodeException: An error occurred during an xcrun execution. Make sure that Xcode and its command line tools are properly installed.
Failed command: /usr/bin/xcrun xcodebuild -version
Try running this command in Terminal and fix the errors by making Xcode (and its command line tools) configuration correct.
package org.example
import kotlinx.serialization.Serializable
import kotlinx.serialization.encodeToString
import kotlinx.serialization.json.Json
@Serializable
data class Greeting(val greeting: String)
fun main() {
println("Hello World!")
println(Json.encodeToString(Greeting("Hello, Kotlin/JS!")))
}
生成されるコードは以下のようになっている。Greeting$serializer.serialize が生成されてるので、実行時には高速に処理ができそうだ。
(kotlin のデコンパイルを IDEA がサポートしてほしいなぁと思いつつ幾星霜)
