* The <<#rel5.0:default_tool_versions,default versions of several code quality plugins>> have been updated.
 * Several <<#rel5.0:library_upgrades, library versions used by Gradle>> have been upgraded.

The following breaking changes will appear as deprecation warnings with Gradle 4.10:

General::

----

There are several options:

1. signature was wrong in the first place, which happens frequently with <<#sec:trusting-several-checksums,dependencies published on different repositories>>.
2. the signature is correct but the artifact has been compromised (either in the local dependency cache or remotely)

        when:
        fails ':a:checkDebug'

        then:
        failure.assertHasCause """The consumer was configured to find attribute 'buildType' with value 'debug', attribute 'flavor' with value 'free'. There are several available matching variants of project :b
The only attribute distinguishing these variants is 'extra'. Add this attribute to the consumer's configuration to resolve the ambiguity:
  - Value: 'extra 2' selects variant: 'bar'

2. It is hierarchical, providing _fine-grained control_ within the overall copy specification.

[[sub:sharing_copy_specs]]
==== 1. Sharing copy specs
Consider a build with several tasks that copy a project's static website resources or add them to an archive.
One task might copy the resources to a folder for a local HTTP server, and another might package them into a distribution.

// lockTimer assists with profiling contention on runtime-internal locks.
//
// There are several steps between the time that an M experiences contention and
// when that contention may be added to the profile. This comes from our
// constraints: We need to keep the critical section of each lock small,

Community plugins also contribute containers, like the `android.buildTypes` container contributed by the Android Plugin.

The Kotlin DSL provides several ways for build authors to interact with containers.
We look at each of those ways next, using the `tasks` container as an example.

            By default, after a dependency is called the first time in a request, if
            the dependency is declared again for the rest of the request (for example
            if the dependency is needed by several dependencies), the value will be
            re-used for the rest of the request.

            Set `use_cache` to `False` to disable this behavior and ensure the

// - a C_FILE with one auxiliary entry for its name
// - C_DWARF symbols to provide debug information
// - a C_HIDEXT which will be a csect containing all of its functions
// It needs several parameters to create .csect symbols such as its entry point and its section number.
//
// Currently, a new file is in fact a new package. It seems to be OK, but it might change
// in the future.

* `outputDir`
+
The directory where the generated files go. As with input files, there are several annotations for output files and directories. A property representing a single directory requires `@OutputDirectory`. You’ll learn about the others soon.
