Resolve gradle build script dependencies

Question

How to check resolve dependencies of build gradle script. For example I have plugin1 and plugin2, how I can figure out what dependencies pull both of them, and each separately?

Is there any parameter to print out this info?

Answer 1

the latest gradle version comes with the buildEnvironment task that does exactly what you need. you can simply run

gradle buildEnvironment

Answer 2

You can use gradle dependencies to get the full list. If your only interesting in a specific module then you can use gradle app:dependencyInsight --dependency com.google.code.gson example for gson

All dependency example outputs are from the project: https://github.com/JBirdVegas/external_jbirdvegas_mGerrit

Here is an example output

EDIT: To get the build script dependencies I think you need a custom task... Something like this

task buildScriptDependencies(type: org.gradle.api.tasks.diagnostics.DependencyReportTask) {
    configurations = project.buildscript.configurations
}

Then you can quickly get the build script dependencies from the command line:

$ gradle buildScriptDependencies
Configuration on demand is an incubating feature.
