Error: Unfortunately you can't have non-Gradle Java modules and > Android-Gradle modules in one project

Question

I have an IntelliJ 14.1.2 Project consisting of two modules - one is an Android Gradle based module and the other is a Spring Java-based module with Maven.

gps-trackman.v1 is my root project and I've not configured any outputs or facets for this project. The app is my android gradle module and I've configured Android and Android-Gradle Facet for this project and gps-trackman isn't my Spring Maven Project. I want to be able to build everything all together. Is it possible?

I now get this error message in my IntelliJ Eventlog

Unsupported Modules Detected: Compilation is not supported for following modules: gps-trackman, gps-trackman.v1, app. Unfortunately you can't have non-Gradle Java modules and Android-Gradle modules in one project.

The project 'gps-trackman.v1' is not a Gradle-based

Is this error just due to a misconfiguration of my project or is it really not possible to have a maven module and a Gradle module in one project?

Do I have to configure any Facets for the root project? Alternatively, do I have to convert my maven to gradle?

Yes, then I've tried to convert the Maven project into a Gradle project, but that resulted in a bunch of other errors, so i would prefer to stay with Maven... — kamokaze, Jan 27 '16 at 19:31

Be careful deleting .idea directory. There is a lot of stuff in that directory that will get lost and not auto-generated when you relaunch A/S. Specifically `codeStyles` and `dictionaries` – tir38 Apr 17 '20 at 17:19

It works for AS 3.6.3 too. I just closed the IDE, deleted the files and reopen. Didn't have to close the project nor import (I believe the IDE does it anyway). – JCarlosR Apr 23 '20 at 15:45
@tir38, I think all the files in .idea folder are auto-generated. No need to worry while deleting. Android Studio creates every file by itself. – Neo May 26 '20 at 09:43

The ultimate solution to this error:

SOLUTION 1

Step 1 Go to File -> Invalidate Caches/Restart.

Step 2 Close the project.

Step 3 Go to project folder and delete .idea folder.

Step 4 Delete YourProjectName.iml in project folder.

step 5 You will see a folder below graddle folder, Delete YourProjectName folder (it contains another YourProjectName.iml file).

Step 6 Open Android studio -> open existing project, and then select your project.

**

SOLUTION 2

**

Step 1: Open the Corrupted Project (The one showing error).

Step 2: Open system.gradle file.

step 3: add this line of code include ':app'.

Step 4: click on the sync, to sync the gradle file.

deleting .idea folder and .iml file helped. – Redar Mar 06 '20 at 13:16 — Redar, Mar 06 '20 at 13:16

In my case settings.gradle contained invalid configuration.

I changed:

include ':app'
rootProject.name='<somthing else>'

To:

include ':app'

Error is gone. So maybe check your settings.gradle for potential errors. If this won't work try to remove cache and other tips.

First of all you should update to Android Studio Source: https://code.google.com/p/android/issues/detail?id=77983

Then you should go to File -> Invalidate Caches / Restart -> Invalidate Caches & Restart.

Then try to build the application again.

Had same issue with Android Studio 3.3 Canary 13.

I was able to solve it by following these steps:

Go to the module settings and remove your module from the list
Edit settings.gradle and remove your module from there also
Physically move the module directory out of the project (to your desktop for instance)
Then in the module settings again add a module and select as type 'Import Gradle Project' in which you select the module folder you have moved to your desktop (or anywhere else)

When you complete these steps the module will be copied into your project again, AS will start syncing Gradle again and that succeeds without errors :-) Check your GIT status and you will see as soon as you add your module directory to GIT again that nothing has changed to your working directory. So it's purely an issue with AS that gets somehow out-of-sync...

Based my solution on this comment: https://issuetracker.google.com/issues/37008041#comment3

This happened when there are some cache issues. Just remove .gradle,.idea and app/build folder.

Goto -> AndroidStudio -> File -> Invalidate Cache & Restart

This will open the same project again and Gradle will rebuild all files and caches. This will take around 10-12 minutes. This will definitely be going to help you.

For me, my project was very corrupted. I don't know how I got into that state. What I observed was that several .gradle file and proguard file had a whole bundle of xml content. Fortunately, the physical file had the correct content in it, but android studio was displaying it as some xml file that looked like it belonged to some generated res xml data. Things like "Sync to file system" or "sync project to gradle file", "invalidate cache and restart" or "gradlew clean" wouldn't clear up the issue. I even replaced the bogus xml data being displayed in the gradle scripts with the original content, but that didn't help either. I tried some of the advise given above, but they either didn't work or seemed too complex for me to feel that me project would go back into a well formed state.

So I elected to create a new blank project. Using file explorer, I copied all of the modules in the corrupted project into the new project (a plain old copy and paste) I also replaced the "settings.gradle" and the root "build.gradle" files of the new file with the contents from the old file. Once that is done, you have to run "sync Project with gradle files and you're good to good. If by chance your project root has some content that you physically added, you would have to copy that over too.

So that gets you back up and working. I don't know for sure what caused my project to get corrupted, but I think it might have to do with the laptop going into sleep mode. My laptop was not allowing me wake up from sleep and the only way for me to wake up was to power off an power on again. I did have some projects opened a few times when that happened. So that's my best guess as to how the project might have gotten corrupted.

None of above worked for me but tried something random and it worked.

Copy the corrupted project directory.
Paste it at somewhere else.
Import it in Android Studio. (File-> New-> Import project)
And uncorrupted project get restored.

PS: You must have original corrupted project. (Means, copy it without tampering project structure)

You can simply downgrade your gradle dependency to fit your current android studio version.

Been dealing with this issue for a while every time I tried opening a project.

I always receive this error even though I knew I had not made any changes that should of caused this apart from exporting to zip.

To Fix:

Make a new project or open project that works
Go to file > open > "your project"
Make sure your dummy project stays open. The project you were getting errors should be opened in a new window.

This fixed it for me without doing any changes or deleting anything.
