@DisableCachingByDefault(because="Produces only non-cacheable console output") public abstract class DependencyInsightReportTask extends DefaultTask
Generates a report that attempts to answer questions like:
  • Why is this dependency in the dependency graph?
  • Exactly which dependencies are pulling this dependency into the graph?
  • What is the actual version (i.e. *selected* version) of the dependency that will be used? Is it the same as what was *requested*?
  • Why is the *selected* version of a dependency different to the *requested*?
  • What variants are available for this dependency?
Use this task to get insight into a particular dependency (or dependencies) and find out what exactly happens during dependency resolution and conflict resolution. If the dependency version was forced or selected by the conflict resolution this information will be available in the report.

While the regular dependencies report (DependencyReportTask) shows the path from the top level dependencies down through the transitive dependencies, the dependency insight report shows the path from a particular dependency to the dependencies that pulled it in. That is, it is an inverted view of the regular dependencies report.

The task requires setting the dependency spec and the configuration. For more information on how to configure those please refer to docs for getEffectiveDependencySpec() and getConfiguration().

The task can also be configured from the command line. For more information please refer to getEffectiveDependencySpec()}, setConfigurationName(String), getShowSinglePathToDependency(), and getShowingAllVariants().

  • Method Details

    • getRootComponentProperty

      @Input @Optional public abstract Property<ResolvedComponentResult> getRootComponentProperty()
      The root component of the dependency graph to be inspected.
      Since:
      7.5

    • getEffectiveDependencySpec

      @Internal @Incubating protected Provider<Spec<DependencyResult>> getEffectiveDependencySpec()
      The effective dependency spec selects the dependency (or dependencies if multiple matches found) to show the report for. The spec receives an instance of DependencyResult as parameter.
      Since:
      9.7.0

    • setDependencySpec

      @Deprecated public void setDependencySpec(@Nullable Spec<DependencyResult> configuredDependencySpec)
      Deprecated.
      use dependencySpec(Spec) instead
      The dependency spec selects the dependency (or dependencies if multiple matches found) to show the report for. The spec receives an instance of DependencyResult as parameter.

    • setDependencySpec

      public void setDependencySpec(@Nullable Object dependencyInsightNotation)
      Configures the dependency to show the report for. Multiple notation formats are supported: Strings, instances of Spec and groovy closures. Spec and closure receive DependencyResult as parameter. Examples of String notation: 'org.slf4j:slf4j-api', 'slf4j-api', or simply: 'slf4j'. The input may potentially match multiple dependencies. See also setDependencySpec(Spec)

    • dependencySpec

      @Incubating public void dependencySpec(@Nullable Spec<DependencyResult> dependencySpec)
      The dependency spec selects the dependency (or dependencies if multiple matches found) to show the report for. The spec receives an instance of DependencyResult as parameter.
      Since:
      9.7.0

    • getDependencyNotation

      @Incubating @Input @Optional public abstract Property<String> getDependencyNotation()
      Configures the dependency to show the report for. Multiple notation formats are supported: Strings, instances of Spec and groovy closures. Spec and closure receive DependencyResult as parameter. Examples of String notation: 'org.slf4j:slf4j-api', 'slf4j-api', or simply: 'slf4j'. The input may potentially match multiple dependencies.

      This method is exposed to the command line interface. Example usage: 

      gradle dependencyInsight --dependency slf4j
      Since:
      9.7.0

    • getConfiguration

      @Internal public Property<Configuration> getConfiguration()
      Configuration to look the dependency in

    • setConfiguration

      public void setConfiguration(@Nullable Configuration configuration)
      Sets the configuration to look the dependency in.

    • setConfigurationName

      @Incubating public void setConfigurationName(@Nullable String configurationName)
      Sets the configuration (via name) to look the dependency in.

      This method is exposed to the command line interface. Example usage: 

      gradle dependencyInsight --configuration runtime --dependency slf4j
      Since:
      9.7.0

    • setConfiguration

      @Deprecated public void setConfiguration(@Nullable String configuration)
      Deprecated.

    • getShowSinglePathToDependency

      @Internal public abstract Property<Boolean> getShowSinglePathToDependency()
      Tells if the report should only display a single path to each dependency, which can be useful when the graph is large. This is false by default, meaning that for each dependency, the report will display all paths leading to it.
      Since:
      4.9

    • setShowSinglePathToDependency

      public void setShowSinglePathToDependency(boolean showSinglePathToDependency)
      Tells if the report should only display a single path to each dependency, which can be useful when the graph is large. This is false by default, meaning that for each dependency, the report will display all paths leading to it.

      This method is exposed to the command line interface. Example usage: 

      gradle dependencyInsight --single-path
      Since:
      4.9

    • getIsShowSinglePathToDependency

      @Internal public Property<Boolean> getIsShowSinglePathToDependency()

    • getShowingAllVariants

      @Internal public abstract Property<Boolean> getShowingAllVariants()
      Show all variants of each displayed dependency.

      Due to internal limitations, this option only works when the configuration is unresolved before the execution of this task.

      This method is exposed to the command line interface. Example usage: 

      gradle dependencyInsight --all-variants
      Since:
