Do not publish stale signature files

This commit fixes the publication of stale signature files:

prior to this change it was possible that a signature generated

in a previous build for a different artifact was uploaded even

if no signature was generated during the build, which would

lead to inconsistent publications.

In addition, it makes it an error to publish something which

doesn't have the main artifact created (or, at least up-to-date)

in this build. In other words, if the task which generates the

main artifact is disabled, it's an error to publish.

Other stale artifacts are going to be ignored.

Publication of resolved versions for Ivy xml

While the feature was added for the Gradle metadata linked to an Ivy

publication, it was missed for the Ivy xml itself.

This commit corrects that, relying on the usage context attributes to

map the Ivy dependency to the requested resolved configuration.

Implement Gradle metadata marker in published pom/ivy files

This commit implements a performance optimization for Gradle metadata.

Given that today there's no library published in any repository with

Gradle metadata, it's much more likely to find a POM (or Ivy) metadata

file for an external dependency, rather than a Gradle metadata file.

If we decided to add `gradleMetadata()` sources by default to all

repositories, then we would probably introduce a performance regression

to a lot of builds, because we would first try to get Gradle metadata,

then fail, and search for POM/Ivy files.

To avoid this, whenever a library is going to be published with Gradle

metadata, we will introduce a _marker_ in the published POM or Ivy

file. When Gradle _resolves_ such a dependency, it will parse the POM

file and look for the marker. If it finds it, then it will _redirect_

to use Gradle metadata instead. This means that when Gradle metadata is

present, we will pay the price of looking for a POM or Ivy file first,

start parsing, only to discover we should parse Gradle metadata. This

should be ok in the beginning, knowing that if `gradleMetadata()` is

added, then we would systematically look at Gradle metadata first.

This means that this is a _temporary_ solution, until Gradle metadata

becomes widespread. So "temporary" should be understood as several

months, if not years.

The marker introduced in POM and Ivy files is _neutral_ for both Ivy

and Maven. By this we mean that it uses an XML comment. While not super

nice, we couldn't use a custom namespace because both Ivy and Maven

fail when parsing this. Properties were considered too, but Ivy doesn't

support them so for consistency both models use comments.

It's worth noting that we will still _completely parse_ the POM or Ivy

descriptor. It's a waste of time, but it helps in case we find a marker

but that for some reason the Gradle metadata file is absent. In this

case we fallback on the model we found.

This change also introduces a change in the semantics of the incubating

metadata sources API: those should be considered _hints_, and not strong

statements anymore.

Finally, should a producer want to avoid publishing Gradle metadata,

it's now possible to disable the task that creates the metadata file.

Add warning for dependency with attributes

Neither Ivy nor Maven support attributes so having attributes defined on

Remove `getUsage` from `UsageContext`

This `Usage` is an artifact of migration. `UsageContext` is mostly representing

what an outgoing published variant is, but this `Usage` is preventing us from

doing smarter things. What we really care about is the attributes of published

variants, and their name for publication.

Allow the services required by a given class to be queried prior to creating any instances of that class. Use this to allow `ArtifactTransformDependencies` to be injected into artifact transforms using any of the service injection patterns (that is, via a constructor or a getter).

Replace most direct usages of `DirectInstantiator` with indirect usages via `InstantiatorFactory` or test fixtures instead. This means more consistent behaviour in unit tests because the objects under test will behave more similarly to how they do at runtime. This also allows the decision of how the instantiation should behave to live in as few places as possible, so this can be more easily evolved and contextualized.

Make AbstractArchiveTask.destinationDir mandatory

Prior to this commit the working directory was used when the

with reproducible builds, it will now fail instead. However, it should

rarely happen because the `base` plugin provides a convention.

Rework task dependency inference so that `Provider` implementations use the same `TaskDependencyContainer` interface that most other things use to declare their producer task to the task resolution infrastructure, rather than having special knowledge sprinkled around various places.

Cleaned up a bunch of `Provider` and `Property` implementations so that more logic is reused rather than reimplemented.

Support propagation of the producer task for provider instances that are created using ``.

Now, when a provider represents a task or task output, whether mapped or not, that task is taken as the producer of the value and the mapping function is not called. Otherwise, the value of the provider is unpacked and resolved, as it previously was.

Rework the protocol by which providers communicate their build dependencies to consumers.

Separate 'prefer' and 'require' in dependency versions

When we introduced the ability to declare a 'preferred' version on

a dependency declaration, this was implemented such that declaring

a "required" dependency version using `org:foo:1.0` was effectively

the same as declaring a "preferred" version `org:foo { prefer '1.0' }`.

In order to differentiate between the behaviour of required and

preferred dependency versions, this commit introduces a separate

model for these constraint types. This model is published to

Gradle `.module` metadata files, and is retained internally

throughout dependency resolution.

At this stage, the behaviour of required and preferred versions

is identical. A later commit will introduce the behavioural

Add dedicated DSL to customize Ivy descriptor to ivy-publish plugin

This commit adds a type safe DSL for customizing the generated Ivy

module descriptor of an IvyPublication to the ivy-publish plugin:

descriptor {

license {

name = 'The Apache License, Version 2.0'

url = ''


author {

name = 'Jane Doe'

url = ''


description {

text = 'A concise description of my library'

homepage = ''



Only interfaces are exposed as part of the public API, all of them are

prefixed with `IvyModuleDescriptor`. The exposed properties make use of

the Provider API.

In addition, the new DSL is documented in the User Guide, DSL Reference

and Release Notes.

Resolves #5193.
