I'm migrating a moderately complex

build.gradle

to

build.gradle.kts

. The file has been going for 14 years, so there's the inevitable layers of fine-then-bad-practice-now stuff. I'm wondering how best to prove I have migrated all the tasks and logic identically. In an ideal world I could export the configured model for all the tasks, I guess, and check it hadn't changed. Does anyone have any tips on implementing such a test? It feels very 20th century to just leap in, start changing things and hope I spot what breaks - some of these tasks are run rarely.

Hello! Is there a way to get all deprecation warnings after a Java compile in Gradle? Currently I am parsing the Gradle output to collect these, but I was wondering if there is a more structured way to do this.

Hello, I'm planning to create a pre-compilation step that can be reused in later CI stages for building and testing (build & test are in the same CI stage). What's the ideal way to achieve this with Gradle? • Is there a recommended approach to compile the project once and use the result in multiple CI stages (e.g., using a shared build cache)? • Would this provide significant benefits in terms of CI performance or stability? • Are there any pitfalls I should be aware of? For additional context: we publish the Gradle build cache once a day (every night), but this pre-compiled result is intended to be reused across stages within the same commit-based pipeline run.

In our in-house gradle distribution, we have multiple init scripts. Is there a way to share some logic between those scripts without having to resort to the

extraProperties

abstraction?

Good morning. I noticed that a good number of public-facing methods that accept Closures aren't annotated with

@DelegatesTo

and/or

@ClosureParams

. Is there a good reason for this or is this just a result of how long Gradle has been around? And would you be open to contributions that add these annotations? I'd appreciate the additional IDE support.

It's been a while since I last looked at this, but I'm now faced with a forced migration from Sonatype Nexus to JFrog Artifactory. The last time I looked at this the official artifactory gradle plugin was a Lovecraftian horror show of cross-project configuration and afterEvaluate logic. Does anyone know if things have got any better in the intervening years, or if there are any reasonable alternatives to the official JFrog plugin that allows us to still use the JFrog server side features (mostly the build metadata stuff).

So I'm facing something quite strange. The content of by file collection seems to vanish between configuration time and execution time oO. I have an interface which like this:

public interface CreateLayerOptions extends LayerOptions {
    @Input
    @Optional
    ListProperty<String> getPackages();

    @Classpath
    @Optional
    ConfigurableFileCollection getJars();

    @Input
    ListProperty<String> getModules();
}

there is, in my code, a single call to `getJars()`:

var classpath = create.getJars();
boolean hasJars = !classpath.getFiles().isEmpty();

The interface is implemented and added to a domain object set using:

@Override
    public void createLayer(Action<? super CreateLayerOptions> spec) {
        var layer = objects.newInstance(CreateLayerOptions.class);
        var binaryName = getName();
        if (!binaryName.startsWith("lib")) {
            throw new IllegalArgumentException("Binary name for a layer must start with 'lib'");
        }
        layer.getLayerName().convention(binaryName);
        spec.execute(layer);
        layers(options -> options.add(layer));
    }

and the user code to configure it currently has (this is all a spike, so hopefully I can make this nicer):

createLayer {
                    val externalJars = configurations.nativeImageClasspath.get()
                        .incoming
                        .artifactView {
                            lenient(false)
                            componentFilter { this is ModuleComponentIdentifier }
                        }
                        .artifacts
                    modules = listOf("java.base", "jdk.unsupported", "java.sql")
                    jars.from(externalJars.resolvedArtifacts
                        .map { artifacts -> artifacts.map { it.file } }
                    )
          ...

When I debug, I can see that after

spec.execute(layer)

is called,

layer.getFrom()

contains one element as expected. However, when my code to get this list of jars is called, the list is empty oO. I have verified and it's the same instance. Only "something" make the contents go away. The suspect is input evaluation, but I'm 🤨

How can I rewrite this snippet using the Kotlin DSL?

test {
   onOutput { descriptor, event ->
       if (event.destination == TestOutputEvent.Destination.StdErr) {
           logger.error("Test: " + descriptor + ", error: " + event.message)
       }
   }
}

I'm struggling on

onOuput

. I guess it's something like

onOutput(closureOf<???> {})

but I don't know what the type is.

Hello again! I've been writing Gradle plugins for a few months now, but I've been relying on manually looking up JavaDocs online for anything in Gradle as IntelliJ is not downloading (or using?) the sources for the Gradle API. Is there any way I can fix that? Or do I just have to cope with using the online JavaDocs for now?

hi, i'd like to be able to reduce boilerplate for our

JavaExec

tasks by presetting some properties like system properties, env properties, classpath, etc, and i am wondering what's the best way for for it would be. these values need to be different based on which environment we want to run in. i have come up with something like this:

abstract class ExecInStaging : JavaExec() {
    init {
        systemProperty("appconfig", "config/staging.properties")
        systemProperty("log4j.configurationFile", "log4j2-local.xml")

        environment("CONSUL_HOST", STAGING_CONSUL)

        classpath = project.extensions
            .getByType<JavaPluginExtension>()
            .sourceSets
            .getByName("main")
            .runtimeClasspath
    }
}

this works - but i am wondering if there are some best practices around this that i am missing? doing all this configuration in the constructor feels a bit weird - especially since now i am getting a bunch of IDE warnings due to

Calling non-final function {} in constructor

... is there a better way to do this?

How can you get the parent directory of a RegularFile as a Directory? Compared to Directory, RegularFile can do "nothing" except calling getAsFile.

Can anyone think of a clever mechanism by which I can retrieve the maven snapshot version (timestamp & build number) of an artifact that was published by the build?

I have a Kotlin/JVM application. I want to pass a lazily system property in using CommandLineArgumentProvider. But for some reason the property doesn't get set correctly and it's not accessible in the application. Properties set using

systemProperty("...", "...")

work, but these are eager and I want to avoid them. Weirdly when I print all properties in the application they appear under a different property -

sun.java.command=org.example.AppKt -DsecretFile=/Users/dev/my-project/secret-file

. I think it's weird there's an inconsistency. I would expect both approaches to work the same. Also, I think it's weird that logging

commandLine

returns a

null

as the first element:

[:run] running task [null, -DsecretFile=/Users/dev/my-project/secret-file]

plugins {
  kotlin("jvm") version "2.1.20"
  application
}

tasks.run.configure {
  val secretFile = layout.projectDirectory.file("secret-file")
  inputs.file(secretFile)

  argumentProviders += CommandLineArgumentProvider {
    listOf("-DsecretFile=${secretFile.asFile.absoluteFile.invariantSeparatorsPath}")
  }
  systemProperty("secretFileWorks", secretFile.asFile.absoluteFile.invariantSeparatorsPath)
  doFirst {
    println("[$path] running task $commandLine")
  }
}

Gradle version is 8.13

I have an init script to apply a project plugin with

lifecycle.afterProject

. But the project does not find the plugin this way, but it finds the plugin if I apply it directly in my build.gradle.kts script.

Hi I have a react native app that I'm trying to create an apk for but i get this error

when i try to compile my plugin with build.gradle.kts this error comes how do i fix it?

Why is it version

8.13

and not

8.13.0

? Gets me every time 😅

Is there a way to add a child CopySpec to AbstractArchiveTask conditionally and lazily? I.e.

if (someCondition) { into(...) { ... } }

but where someCondition is a boolean Property?

so, I'm playing with variants (for native libraries) and I'm looking into re-publishing some libraries under new coordinates it works fine for a single artifact with multiple variants, but I'm wondering if I could combine multiple artifacts: ie:

org.jogamp.gluegen:gluegen-rt

,

org.jogamp.joal:joal

, etc code here, I can work around for the configurations and the publications, but the

javaComponent

is a problem, or does anyone see a way?

Hello guys. How are you? I am using gradle on macOS. I am getting this error. How can I fix it? The libzip.dylib file exists in the folder correctly.

% ./gradle
Error occurred during initialization of VM
Could not resolve "ZIP_Open": /Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home/lib/libzip.dylib

Is it expected to still see

java.lang.System::load

warnings with Gradle 8.14 and Java 24? I would think not because of #31625, but not sure. Never mind, Renovate didn't run the wrapper task correctly (message below is still relevant though).

I'm seeing lots of these errors coming from multiple libraries after updating to Java 24. Is the correct solution to add

--enable-native-access=ALL-UNNAMED

to my jvm args until all of these libraries/tools migrate off of JNI (so probably never)?

Does anyone know about a Gradle plugin that allows to embed metadata about Java / Kotlin resources into the compiled JAR? For example, I'd like to get the source code path (relative to the repository root) of a resource at runtime of the application.

I've tried installing Gradle a few times already following different tutorials and I follow every step but then when it gets to the cmd part I type "gradle --version" and it gives me the same error every time "Error: -classpath requires class path specification", I really don't know what to do, I've tried at least 5 different tutorials went so far to even ask AI and I still don't know what to do. Can someone please help me?

I wonder, what is the current way to go for

ConfigurableFileCollection

vs

ListProperty<RegularFile>

Is there anything like “prefer

ConfigurableFileCollection

in newer code” or “prefer

ListProperty<RegularFile>

in newer code” ? I assume the answer should be the same for both task properties and extension properties, however, it would be great to learn if there’s a difference.

I've locally re-published jogl glugen library under new coordinates keeping the main artifact as

org.jogamp.gluegen:gluegen-rt

and the natives as variants now I'm on the consumer side, with a test project, expanding the runtime configuration for each variant, adding the corresponding file underneath, but Gradle complains:

Could not resolve org.jogamp.gluegen:gluegen-rt:0.0.8 for variant-tester:main
Could not resolve org.jogamp.gluegen:gluegen-rt:0.0.8 for variant-tester:test

I have some issues about gradle on my project. Can anyone help me to solve it

is there any way to make this Gradle task cacheable?

tasks.register("updateModuleCapabilitiesIndex") {
    val watchFiles = fileTree(project.rootDir) {
        include("**/build.gradle", "**/build.gradle.kts")

}

Command removed for simplification, but I'm trying to write something that parses the gradle files and then saves the info into another file in a cacheable way. The doLast{...} bit unfortunately contains a gradle script which is not serializable... Tried to search in this slack but configuration cache gets a lot of unrelated hits 😂

Why is my Gradle plugin causing
