All thanks to the Gradle dependency tree. Declaring Dependencies between Subprojects, Understanding Configuration and Execution, Writing Custom Gradle Types and Service Injection, Understanding Library and Application Differences, Producing and Consuming Variants of Libraries, Modeling Feature Variants and Optional Dependencies. For example, source files are .java files for JavaCompile. If you want to get your hands on the Gradle task graph yourself during your build, thankfully thats pretty straightforward with the org.gradle.api.execution.TaskExecutionGraph interface. It works fine! This binary file is small and doesn't require updating. You can declare dependencies for external tooling with the help of a custom dependency configuration. However, I was looking for something that gives more of a tree view, so that I can easily detect what causes a specific task to run, for instance if I want to check why the task myCustomTask runs when I run gradle build. In the examples above, it is still possible to execute taskY without causing taskX to run: To specify a must run after or should run after ordering between 2 tasks, you use the Task.mustRunAfter(java.lang.Object) and Task.shouldRunAfter(java.lang.Object) methods. Normally, the task searches classes under build/classes/java/main (for Gradle 4+), which is the default class directory for Gradle builds. The dependency appeared multiple times, with different version requests. its easy to forget about those: because you may run build often, you might think that your build works, because jar is part of the task graph, and by accident, the docsFileJar would be executed before. ./gradle tasks lists "some" of the tasks. (c): This element is a dependency constraint, not a dependency. You also learned how to add additional behavior to these tasks later on, and you learned how to create dependencies between tasks. sonarQubeRunAnalysis - Run SonarQube or SonarCloud Analysis In practice, its worth noting that 2. is a subset of 3. but I added it for clarity.

The ordering rule only has an effect when both tasks are scheduled for execution. Finalizer tasks will be executed even if the finalized task fails or if the finalized task is considered up to date. To execute a task, Gradle has to understand the tasks available in the project and what dependencies the task has. We just run the dependencies Gradle task, like this: Under compileClasspath is a simple tree structure, represented by the dependencies we declared in build.gradle, and any transitive dependencies. testResultsFiles - Test results files Simple Gradle tasks are like Ants targets, but enhanced Gradle tasks also include aspects of Ant tasks. Both of the following examples show dependencies in the testRuntimeClasspath dependency configuration of a Java project: To see a list of all the configurations available in a project, including those added by any plugins, you can run a resolvableConfigurations report.
