📜 Description

Removes outputs.upToDateWhen { false } from the systemTest tasks in the sentry-samples/* modules, and replaces it with proper Gradle input tracking via a new io.sentry.systemtest convention plugin.

The system tests launch the packaged sample app (shadowJar/bootJar/war) from build/libs as a separate process — it is not on the test classpath. With only outputs.upToDateWhen { false } removed, Gradle would compute up-to-date purely from the test classes and runtime classpath, so a separate jar build could refresh the artifact while systemTest was skipped, meaning the assertions never ran against the rebuilt sample.

Rather than repeat the input wiring in all 22 sample build files, it lives in one build-logic convention plugin (build-logic/src/main/kotlin/io.sentry.systemtest.gradle.kts), following the existing io.sentry.spotless / io.sentry.javadoc pattern. The plugin auto-detects the packaging task with precedence war → shadowJar → bootJar (mirroring test/system-test-runner.py) and declares its archive as a systemTest input + dependency:

tasks.matching { it.name == "systemTest" }.configureEach {
  val archiveTask = when {
    tasks.findByName("war") != null -> "war"
    tasks.findByName("shadowJar") != null -> "shadowJar"
    tasks.findByName("bootJar") != null -> "bootJar"
    else -> null
  }
  if (archiveTask != null) {
    dependsOn(archiveTask)
    inputs.files(tasks.named(archiveTask))
      .withPropertyName("appArchive")
      .withNormalizer(ClasspathNormalizer::class.java)
  }
}

Each sample just applies id("io.sentry.systemtest"); the existing inline systemTest blocks are otherwise unchanged. configureEach defers the wiring until the task is realized (no afterEvaluate), at which point the packaging plugins are already applied.

💡 Motivation and Context

outputs.upToDateWhen { false } disabled up-to-date checks and build cache reuse for the systemTest tasks, because the launched JAR/WAR was not modeled as a task input. This models that input properly — in one place — instead of disabling incremental builds wholesale.

💚 How did you test it?

• ./gradlew spotlessApply / spotlessCheck pass (the new plugin compiles and applies).
• ./gradlew --dry-run :sentry-samples:<module>:systemTest for a console (shadowJar), Spring Boot 2 (shadowJar), Spring Boot 4 (bootJar), and Tomcat (war) module confirms the packaging task is now wired into the task graph ahead of systemTest.
