I only reviewed commit 1274a6f, there's some nice fixes, and ideas that align with previous work in #10402, there's also fixes that I don't think are useful for Gradle 9 migration like:

-  def javaDir = buildDir.toPath().resolve("generated/sources/tries/java/${sourceSetName}")
+  def javaDir = project.layout.buildDirectory.dir("generated/sources/tries/java/${sourceSetName}")

This commit alone touches a lot of files. Some changes can be split to smaller PRs.

I'm weighing on toggling off failOnNoDiscoveredTests, maybe there's some "file" detection to add in the addTestSuite methods.

bric3 · 2026-05-05T14:33:48Z

  testJvmConstraints {
    minJavaVersion = JavaVersion.VERSION_21
  }
+  failOnNoDiscoveredTests = false


suggestion: I've seen this as well albeit not when trying Gradle 9.3 on dd-trace-java, IIRC... I think a better solution is to add that flag within the logic of addTestSuiteExtendingForDir, addTestSuiteForDir, this could prevent adding this every time these test suite methods are used.

  // dependency 'log4j-over-slf4j' brought in by :dd-java-agent:testing which would shadow
  // the log4j module under test using a proxy to slf4j instead.
-  testCompile.exclude group: 'org.slf4j', module: 'log4j-over-slf4j'
+  testImplementation.exclude group: 'org.slf4j', module: 'log4j-over-slf4j'


question: What was the problem with testCompile ?

bric3 · 2026-05-05T15:20:18Z

+// Gradle 9 daemon JVM is JDK 17, but this WAR is deployed to a WildFly server
+// that may run on Java 8 (testJvmConstraints maxJavaVersion=11). Pin a Java 8
+// toolchain so the produced bytecode loads on the lowest supported test JVM.
+java {
+  toolchain {
+    languageVersion = JavaLanguageVersion.of(8)
+  }
+}


thought: interesting 🤔

+// define the task that builds the EAR via a sub-Gradle invocation.
+//
+// The sub-build inherits this project's wrapper (Gradle 9.4.1), whose daemon
+// requires JDK 17 — that's why JAVA_HOME is 17, not the test runtime version.
+// The deployed WAR's compile target is pinned separately in
+// spring-ear/war/build.gradle via a Java toolchain.
 tasks.register('earBuild', Exec) {
  workingDir "$appDir"
  environment += [
    "GRADLE_OPTS": "-Dorg.gradle.jvmargs='-Xmx512M'",
-    "JAVA_HOME": getLazyJavaHomeFor(8)
+    "JAVA_HOME": getLazyJavaHomeFor(17)
  ]
-  commandLine "$rootDir/${gradlewCommand}", "assemble", "--no-daemon", "--max-workers=4", "-PappBuildDir=$appBuildDir", "-PapiJar=${project(':dd-trace-api').tasks.jar.archiveFile.get()}"
+  commandLine "$rootDir/${gradlewCommand}", "assemble", "--no-daemon", "--max-workers=4",
+    "-PappBuildDir=${appBuildDir.get().asFile.absolutePath}",
+    "-PapiJar=${project(':dd-trace-api').tasks.jar.archiveFile.get().asFile.absolutePath}"


suggestion: We may need a more general way to invoke Gradle for sub projects. Actually, even relying on an older Gradle distribution is on the table.

              project.configurations.api.allDependencies.each {
-                if ((it instanceof ProjectDependency) || !(it instanceof SelfResolvingDependency)) {
+                if (it instanceof ModuleDependency) {


suggestion:

Suggested change

if (it instanceof ModuleDependency) {

if (it instanceof ProjectDependency || it instanceof ExternalModuleDependency) {

Handled in #11340

bric3 · 2026-05-05T15:59:28Z

suggestion: Let's avoid again another script plugin, this could be a correct convention plugin dedicated for smoke tests.

Also, spring-boot-plugin.gradle and this can be "merged" as a single plugin.

+      def stderr = new ByteArrayOutputStream()
+      def process = new ProcessBuilder('git', 'rev-parse', '--short', 'HEAD').start()
+      process.waitForProcessOutput(stdout, stderr)
+      if (process.exitValue() != 0) {
+        throw new GradleException("Unable to determine git hash: ${stderr.toString().trim()}")


issue: this is the wrong fix

bric3 · 2026-05-05T16:14:28Z

Also, did bumping to Groovy 4 was needed to make everything work ?

AlexeyKuznetsov-DD · 2026-05-05T19:43:00Z

Also, did bumping to Groovy 4 was needed to make everything work ?

@bric3 If I recall correctly I have to bump codenark and also smoke tests for gradle are using gradleTestKit()
But probably we can keep Groovy 3 with manual override where needed.
