[gradle] Using gradle to find dependency tree

Is it possible to use gradle to produce a tree of what depends on what?

I have a project and would like to find out all the dependencies so I may be able to prune it a little with forward declarations etc.

This question is related to gradle

The answer is

For me, it was simply one command

in build.gradle add plugin

apply plugin: 'project-report'

and then go to cmd and run following command

./gradlew htmlDependencyReport

This gives me an HTML report WOW Html report

Or if you want the report in a text file, to make search easy use following command

gradlew dependencyReport

enter image description here

That's all my lord.

I also found useful to run this:

./gradlew dI --dependency <your library>

This shows how are being dependencies resolved (dependencyInsight) and help you debugging into where do you need to force or exclude libraries in your build.gradle

See: https://docs.gradle.org/current/userguide/tutorial_gradle_command_line.html

In Android Studio (at least since v2.3.3) you can run the command directly from the UI:

Click on the Gradle tab and then double click on :yourmodule -> Tasks -> android -> androidDependencies

The tree will be displayed in the Gradle Console tab

An image is worth a thousand words

Things have moved forward in Gradle so I believe this question merits another answer.
Since Gradle 4.3, "build scans" were introduced. All relevant info is available in the Gradle docs (1, 2). For me, this seems to now be the easiest way to check your dependencies (and generally your build) in a clear, organized way.

They are very easy to create, just execute:

gradle build --scan  

(or ./gradlew build --scan if you use a wrapper)

This produces a randomly generated link where you can see your scan. When opening that link, you enter your email and gain full control of the link: eg. share it or delete it. It has got a lot of info about your build, not just dependencies. You can see your dependencies, their hierarchies, the repository used to obtain them but also a lot of other stuff about your build, namely, its performance (which is of interest in big complex builds), your tests, even your console output and your system configuration, which JDK and JVM was used, max heap size etc.

This is a printscreen from a mock project:

Build scan example

A build scan is a shareable record of a build that provides insights into what happened and why. You can create a build scan at scans.gradle.com for free.

Note however, that info for your build process will be sent to the Gradle servers. You have full control to delete it when you are finished with your inspection.

Finally, you can use build scans with Gradle versions earlier than 4.3 too, you just have to manually add the scans plugin in your buildscript.

Incorporating some feedback from the comments some extra notes:
1) It is very difficult to do this by mistake or without understanding that some info for your build will be online (private to you, with the ability to delete it, but still online).

When executing gradle build --scan the following message appears:

Publishing a build scan to scans.gradle.com requires accepting the Gradle
Terms of Service defined at https://gradle.com/terms-of-service. Do you
accept these terms? [yes, no]

You have to explicitly write yes and then the message continues:

Publishing build scan...  

2) In Gradle Enterprise you can host gradle build scans in your own servers. However I have no experience in this and my proposed approach was about the standard Gradle distribution, using Gradle's servers for your build scans.

3) Gradle itself promotes the build scans as the way to deal with most your build problems.

Note that you may need to do something like ./gradlew <module_directory>:<module_name>:dependencies if the module has extra directory before reach its build.gradle. When in doubt, do ./gradlew tasks --all to check the name.

Often the complete testImplementation, implementation, and androidTestImplementation dependency graph is too much to examine together. If you merely want the implementation dependency graph you can use:

./gradlew app:dependencies --configuration implementation

Source: Gradle docs section 4.7.6

Note: compile has been deprecated in more recent versions of Gradle and in more recent versions you are advised to shift all of your compile dependencies to implementation. Please see this answer here

For recent versions of Gradle (I tested with the 6.4.1 version):

gradle dependencies --configuration compileClasspath

or if you're using the Gradle Wrapper:

gradlew dependencies --configuration compileClasspath

When building for Android with the 'debug' and 'release' compilation profiles, the debugCompileClasspath and releaseCompileClasspath configurations can be used instead of compileClasspath.

For Android, use this line

 gradle app:dependencies

or if you have a gradle wrapper:

./gradlew app:dependencies

where app is your project module.

Additionally, if you want to check if something is compile vs. testCompile vs androidTestCompile dependency as well as what is pulling it in:

./gradlew :app:dependencyInsight --configuration compile --dependency <name>
./gradlew :app:dependencyInsight --configuration testCompile --dependency <name>
./gradlew :app:dependencyInsight --configuration androidTestCompile --dependency <name>

If the application doesn't use modules, try:

gradle dependencies

If you want all the dependencies in a single file at the end within two steps. Add this to your build.gradle.kts in the root of your project:

project.rootProject.allprojects {

    this.task("allDependencies", DependencyReportTask::class) {


Then apply:

./gradlew allDependencies | grep '\-\-\-' | grep -Po '\w+.*$' | awk -F ' ' '{ print $1 }' | sort | grep -v '\{' | grep -v '\[' | uniq | grep '.\+:.\+:.\+'

This will give you all the dependencies in your project and sub-projects along with all the 3rd party dependencies.

If you want to get this done in a programmatic way, then you'll need a custom renderer of the dependencies - you can start by extending the AsciiDependencyReportRenderer that prints an ascii graph of the dependencies by default.

You can render the dependency tree with the command gradle dependencies. For more information check the section 11.6.4 Listing project dependencies in the online user guide.

If you want to visualize your dependencies in a graph you can use gradle-dependency-graph-generator plugin.

Generally the output of this plugin can be found in build/reports/dependency-graph directory and it contains three files (.dot|.png|.svg) if you are using the 0.5.0 version of the plugin.

Example of dependences graph in a real app (Chess Clock):


If you find it hard to navigate console output of gradle dependencies, you can add the Project reports plugin:

apply plugin: 'project-report'

And generate a HTML report using:

$ ./gradlew htmlDependencyReport

Report can normally be found in build/reports/project/dependencies/index.html

It looks like this: enter image description here

For Android, type this in terminal

gradlew app:dependencies

It will list all the dependencies and the ones with newer versions for you to upgrade like

com.android.support:customtabs:26.1.0 -> 27.1.1 (*)

In Android Studio

1) Open terminal and ensure you are at project's root folder.

2) Run ./gradlew app:dependencies (if not using gradle wrapper, try gradle app:dependencies)

Note that running ./gradle dependencies will only give you dependency tree of project's root folder, so mentioning app in above manner, i.e. ./gradlew app:dependencies is important.
