I want to use Gradle for my Android project, and I use Eclipse (rather than Android Studio). My web-search pointed me to Eclipse's Gradle Plugin called Buildship. I downloaded and installed it following this guide.
My need is to convert my Android project in my Eclipse workspace into something that works with Gradle build system. So following this section of the guide mentioned, I added Gradle support to my project. But I still can not see a build.gradle file in my project. I did refresh the project.
So what do I do to get a build.gradle file in my project?
*The guide I linked to says, *
Run the 'gradle init' task to create the initial Gradle files, in case
you do not have them yet.
but I can't figure out how to run the gradle init task.
In the "Gradle Tasks" panel, expand the node of your project. Then expand the "build setup" node. Right click on "init" and select "Run Gradle Tasks".
Then in the project explorer, right click on your project and select "Gradle", then select "Refresh Gradle Project". And voila! You must be able to see your build.gradle now.
Go to windows-->Show View-->Gradle Tasks. In this view you will be able to see your project.Expand build setup and double click "init" task.

When I try to run the application I get a message that I should choose the configuration.
When I do, I try to go with AndroidApplication, and then I get this message with an error saying module not specified. But when I try to choose a module from the dropdown, I get no options.
How can I fix this? Thank you!
I see two possible issues:
1) I don't see that you are using gradle(no gradle files shown in your 'project view', and I don't see the 'Gradle Scripts' drop down in the 'project view'.
This is an issue because it looks like this project is from Eclipse, not Android Studio. The inclusion of 'project.properties' hints at this too. Android Studio doesn't include the ant-based build system that can build a project from the Eclipse build system.
If this is the problem then close the project, and use the 'Import Project' wizard from the "Welcome to Android Studio" start window and re-import your proeject. This wizard will import the project for you and convert it to use the gradle build system.
2) If you ARE using gradle (and it just looks like you aren't)... Then this might be your problem...
In your 'settings.gradle' file (topmost level of your project...)
You should have something like
include ':<library-etc(obviously just placeholder)....>'
include ':app'
":app" here refers to the folder where your project lives. If it isn't in your 'settings.gradle' file then it won't be listed as a 'module' you can configure.
No matter what projects I import they never work - Android Studio is always flagging this is not a Gradle build project.
I select VCS -> GIT and clone the repo without any problem. I then go through the wizard with no issues (I select create project from existing sources), creating my code base with a warning, below. When i try to run throws all sorts of errors.
Migrate Project to Gradle? This project does not use the Gradle build
system. We recommend that you migrate to using the Gradle build
system. More Information about migrating to Gradle.
Don't show this message again.
When I go to the link it makes no sense whatever to me, it says to create an arbitrary Gradle file and populate it with my references (I think), which is out of my understanding. I shouldnt have to do this as it says in the repository instructions that it is in fact a Gradle-based project.
The project I am trying to clone is
https://github.com/googlesamples/android-play-location.git
Can anybody tell me specifically how to import and run the following git repo in Android studio for example?
Ok from the start (as i dont know what other way works)
Go to Git master page (it has 'download to zip' or 'clone to desktop' button). use https://github.com/googlesamples/android-play-location as a test master page if you like to ensure you have no other issues i did not.
Click 'download zip'
Unzip the project
Close the current project in Android Studio -> File/Close Projects
A popup screen like this will appear, choose Import Project (Eclipse ADT, Gradle etc.)
You will be asked to select the project, select your unzipped project within the master folder, eg basicLocation
Select 'create project from existing resources' default
dont change project name (may cause issues)
Next through 'import project -> directories'
Next through project -> libraries
Next Through import projects -> modules and module dependencies
Next through import project ->SDK
Next through import project ->manifest.xmls
Android Studio starts. Ensure the configurations dropdown has a project in it called 'app' app
Select 'sync Gradle' icon (green circle)
May get language warning, ignore or accept restart, doesnt matter
At bottom it should now say 'Gradle executing tasks' after which it will run on device or emulator :)
Short answer: File > Open > the build.gradle file you just cloned with the repo
I just wanted to add this, because I had the same problem, and even if Fearghal´s answer and comments pointed me in the right direction, I think he may have added unnecesary extra steps, i.e. Download as ZIP, Close current project, etc.
Simply put, you VCS > Git Clone, and then open the build.gradle file. That´s it
This can happen for many reasons. I typically see it when I move the directory. The easiest way I have found is to close the project and then reopen it using "Import project (Gradle, Eclipse, ADT, etc.) menu item then selecting the folder. This will force it to reimport the project and fix any metadata/configs.
What worked for me was
On Android Studio
Open the settings.gradle file
include your project
include ':myproject'
Well, as Android Studio correctly says, https://github.com/googlesamples/android-play-location is not a Gradle project.
Any subdirectory of that repository is however.
They are different projects.
So clone that repository and import one of its subdirectory in Gradle.
When I open my project in Android Studio, I always get this.
Back when Android Studio first came out, I went through this process so the project should have the Gradle build system. There is a build.gradle file in the root of the project.
I can still build and run the project, but I don't understand why it always says this since the project should use gradle build system. Any help with this would be great.
The android studio support two "build mode". one is "legacy" and one is "gradle based". If you are using an very early version of android studio, probably you are still using the legacy build mode. You need to re-import your project using "gradle mode" then this warning will be gone.
To do so, select "file/import project", select your project root directory, and in the next dialog choose "Import project from external model" and select gradle. Then, you may choose "gradle wrapper" or use your own gradle distribution (1.8 for now[12/2013]).
This link can help, https://developer.android.com/studio/intro/migrate.html
Import as a Project:
Start Android Studio and close any open Android Studio projects.
From the Android Studio menu click File > New > Import Project.
Alternatively, from the Welcome screen, click Import project (Eclipse ADT, Gradle, etc.).
Select the Eclipse ADT project folder with the AndroidManifest.xml file and click Ok.
i know this is an old question but is still valid with newer versions of AS.
If you try to import and import againa and still have the same issue, check if there's a gradle.build file on the root directory, if there's not just create one.
In my case I had to migrate an old project to the new version because with the 0.4.4+ version it stopped recognizing it, and it kept failing, and that was the problem.
Curious thing is the top level build.gradle file just contains this comment:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
I fixed this issue with the following steps:
Make sure that the following two files are in your project directory. If not, create a new one with reference of your other Android projects. These are default auto-generated files.
settings.gradle
build.gradle
If it is still showing any errors when you open your project, restart your project by selecting file/(invalidate /restart).
import Project
File --> New -->import Project
In my case the the problem was that studio version I am using does not support the gradle version of file, so in build.gradle I had to change the gradle version to 2.3.0 and everything is smooth now
I have a multi-project setup in Gradle and work in Android-studio. The setup contains two apps (each one has its own project directory with its own build.gradle) and some libraries shared by those apps.
The directory structure looks like this:
/workspace/
/workspace/app1/
/workspace/app2/
/workspace/app3/
/workspace/library1/
/workspace/library1/
When I build from the command line I can limit the build to only one of the apps via
gradle assembleDebugApp1
When I build from within Android Studio, it seems to build all projects that have a build.gradle file and are inside of workspace.
In Android Studio, when I run Build->Make Project, I see on the bottom what gradle does:
Gradle build using tasks: [:app1:assembleDebug, :app2:assembleDebug, library1:bundleDebug, (...)].
I would like it to only run the assemble task for my "current project".
I'm new to AndroidStudio, so maybe the question is : How do I set the "current project'?
How do I tell Android Studio to only build what I need for app1?
Edit based on replies:
I do want to run gradle via make so it does give feedback back to the IDE, because I'd like to see the "Make Messages" window:
Open Gradle tasks tab and select task to run. You can select a task from subprojects.
On command line:
gradle :app1:assembleDebug
I'm not sure if there is an "official" way of handling this yet but I got around it by creating a new "Run Configuration" and replacing the default "Build" option in the "Before Launch" section with my own command that calls Gradle with the relevant command line options.
I try to import an eclipse project into Android studio.
In the migration instructions it says "In the following dialog, leave Use gradle wrapper selected and click OK. (You do not need to specify the Gradle home.)"
The problem is that the ""Use gradle wrapper" is unselected and grayed out.
Any suggestions?
1) Create a new simple project with Android Studio.
2) Find the gradle folder in the new project.
3) Use the export option in eclipse to create the build.gradle script. (Requires at least adt version 22.0)
4) Copy the gradle folder into the project you want to export to Android Studio.
5) Now try to import this project, u shall be able to select the wrapper check box.
This may resolve the problem you asked for, you can also set the Gradle home path and use the other option just fine.
Hope this helps!
I had this issue with a project that I had already previously built using Android Studio. It turned out that selecting the project appended a /gradle to the path of the directory when searching for a gradle wrapper. Removing the /gradle allowed me to select the option to use the default gradle wrapper.
For those intellij + Gradle users, that arrive here via Google...
I had the same "greyed out" issue, on osx, NOT on an Android project though.
To resolve, I had to...
Install gradle. (If not already installed)
(if you use Homebrew)
`> brew install gradle `
In the terminal, remove your gradle/wrapper folder.
Run the gradle wrapper task (this will download/create the wrapper)
> gradle wrapper
Attempt to re-import the project in intellij
I had an existing project with this problem. I already had gradle on my system, so what I did to fix it was remove everything from my build.gradle except:
task wrapper(type: Wrapper) {
gradleVersion = '1.10'
}
If you don't have a build.gradle, create one. Then run gradle wrapper. This will download the wrapper. Then put the original (Android-ish) contents of your build.gradle back, and go to your Project Settings in IntelliJ/ADT. You should be able to choose the Use gradle wrapper option now
Here's the simpliest sollution which works for both AndroidStudion and Intellij Idea
Go to Preferences -> Build, Execution.. -> Build Tools -> Gradle
Check "Use gradle wrapper task configuration"
Click apply (gradle wrapper will be downloaded, gradlew, gradle.bat files will be added to your project)
Check "Use default gradle wraper"
I had this issue and the only way I found to fix it was by deleting my Eclipse and SDK directories, deleting the settings/preferences, as well as my Android Studio settings/preferences. It isn't the most elegant solution, but I was able to get it to work by doing this.
My suspicion is that something wasn't happening right during Export, because it was the last variable I changed after already attempting a reinstall of Android Studio.
As someone else said, you need to first create a new project with android studio, and use the gradle file found in that project and paste it into the project which you want to import.
