Gradle Enterprise 2019.3

Gradle Enterprise 2019.3 introduces build failure analysis for triaging and diagnosing unexpected build failures for Gradle and Maven builds, test results and console logs for Maven builds, improved support for the latest Gradle dependency management features, and more.

Read on for more details.

Use version 1.2.8 of the Gradle Enterprise Maven extension, and version 2.4.2 of the Gradle build scan plugin for optimal usage of Gradle Enterprise.


Build failure analysis

This release of Gradle Enterprise includes tools for identifying and investigating build failure patterns within your organization.

The top failures report shows the most frequent Gradle and Maven build failures, grouped by cause and charted over time.

Gradle Enterprise partitions source code verification failures (compiling, linking, testing, linting, and so on) from non-verification failures. This will surface problems such as build configuration or infrastructure failures that are likely to be unexpected and disruptive.

Selecting a failure initiates a search for all occurrences of that failure; along with breakdowns by day, user, build hostname, and common tags.

You can search for failures you’re interested in by their message. For example, you can search for “**” to quickly see how often builds fail due to a repository being flaky or offline.

Learn more in this blog post introducing the failures dashboard.

Test results for Maven builds in build scans

Build scans now include the results of all tests executed by the Surefire or Failsafe plugins when using JUnit 4, JUnit 5 or TestNG test execution frameworks.

The build scan summary indicates the longest running tests of the build.

The tests view lists all executed tests, slowest to fastest. The tests can also be viewed by project, or be filtered to only the failed tests.

Failed tests can be clicked to see the failure exception for the test.

Capturing Maven test executions requires Maven extension 1.2+, as well as Surefire/Failsafe plugin 2.15+. The test framework used to run the test must be JUnit4, JUnit5 or TestNG


Console logging for Maven builds in build scans

Build scans now also reproduce the console logging for Maven builds. This makes it easier to share and collaboratively debug builds.

The console log can be filtered for a given goal execution, which is particularly useful for the intertwined logging of builds executed in parallel.

Capturing Maven console log requires Maven extension 1.2+.

Workspace build history for Maven builds

Maven build scans now provide easy access to build scans of earlier and later builds of the same workspace (i.e. the same project directory or checkout). 

This feature is particularly useful when remotely debugging an unexpected local build failure as it allows inspecting and comparing all builds of a session of builds.

Dependency download time visualization

The build performance and trends dashboards now visualize how much build time was spent obtaining dependencies. 

This visualization is particularly useful for identifying the build time cost of ephemeral CI builds (i.e. CI builds that do not have access to any persistent file storage for local dependency caches), poor network performance, or frequent dependency changes (e.g. snapshots). It can also be used to measure and confirm potential improvements such as use of dependency repository proxies.

More fine-grained Gradle task duration breakdown in build scans

The details inspector of a task within the Timeline section of the build scan now indicates how much time was spent downloading dependencies and how much time was spent doing the actual task work (e.g. compiling code). This can be used to diagnose long task execution times.

If a task is the first executed that requires a set of dependencies, they must be resolved before the task can do its work. This time is included in the overall task duration visualized in build scans, but isolated in the details inspector.

Before and after performing a task’s work (i.e. executing its actions), Gradle must perform internal work such as inspecting the task’s inputs and outputs. The discrepancy between the task action execution time and the overall task duration effectively indicates the cost of this internal work.

Task dependency download breakdown requires build scan plugin 2.4+. Task action execution breakdown requires build scan plugin 2.4+ and Gradle 5.6+.

Enhanced Gradle dependency insights

Over the last several releases, Gradle has gained new dependency management capabilities such as dependency variants, rich version constraints, and platforms. Build scans for Gradle builds now more thoroughly visualize these new features and have been improved with more search functionality.

It is now possible to filter the dependencies visualization by project and configuration. This makes it easier to investigate dependency graphs of large multi-project builds.

The new “Versions” tab in the dependency inspector shows the different requested dependencies that resolved to the dependency being inspected due to substitution. This makes it much easier to identify the other dependencies that caused a particular dependency to be substituted. 

When a dependency selection occurs as the result of conflict resolution and/or resolution rules, the dependency inspector now shows all of the reasons that led to the selection where previously only one was shown.

Display of all dependency selection reasons requires build scan plugin 2.4+.

Platform and dependency constraints are now clearly marked in the dependency details view. These types of dependencies are used when leveraging Maven BOMs or when using dependency platforms directly

Dependency constraint display requires build scan plugin 2.4+ and Gradle 5.1+. Platform dependency display requires build scan plugin 2.4+ and Gradle 5.2+.

Gradle supports variant-aware dependency management, where different variants of a dependency can be selected based on attributes and capabilities (e.g. debug vs. release). Build scans now indicate the variant name of a dependency when more than one variant of the same dependency are present in a given configuration. The variant name, attributes and capabilities are also visible in the details inspector.

Dependency variant display requires build scan plugin 2.4+ and Gradle 5.6+.

Finally, rich dependency version constraints are now displayed in the dependency details view, more usefully showing what version constraints were requested for a particular dependency.

Rich dependency version constraint information requires build scan plugin 2.4+ and Gradle 5.1+.

Build logic dependencies in Gradle build scans

Gradle build scans now include a new Build dependencies section that visualizes the build logic dependencies. This section includes both buildSrc dependencies and classpaths for build scripts. This makes it easier to debug dependency version conflicts of Gradle plugins and other dependency issues.

Build dependencies can also be compared between builds.

Build dependencies display requires build scan plugin 2.4+.

Enhanced Gradle Enterprise Maven Extension Build Scan API

The Gradle Enterprise Maven Extension Build Scan API now offers the same functionality as its Gradle counterpart, allowing programmatic control over build scan publishing and other aspects.

For example, you can use the BuildScanApi.publishAlwaysIf() method to publish only if a CI system property is set or based on any other criteria. 

See the Gradle Enterprise Maven Extension User Manual for details and examples of how to use the API in your own Maven plugin or extension, or with the Groovy Maven plugin.

Upgrade notes

If upgrading from a version of Gradle Enterprise prior to 2019.2, be sure to also consult the release notes for all interim versions.

Degraded performance due to data reindexing

Upon upgrading, a data reindexing process will be initiated in the background with Gradle Enterprise being usable for its duration. CPU usage will be increased and performance may be slightly degraded. For large installations storing many build scans, the reindexing process may take several hours.
