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?

Solution 1

1- close the project

2- close Android Studio IDE

3- delete the .idea directory

4- delete all .iml files

5- open Android Studio IDE and import the project

Answer from here

Solution 2

1. Go to File -> Invalidate Caches/Restart.
2. Close the project.
3. Go to project folder and delete .idea folder.
4. Delete YourProjectName.iml in project folder.
5. Delete app.iml in app folder.
6. Open Android studio -> open existing project, and then select your project.
7. The Load Settings error and Unsupported modules detected error will be gone.

Solution 3

1. Close the project
2. Just delete the modules.xml in .idea folder.
3. Open the project again.

Solution 4

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.

Solution 5

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.

I don't use android studio . this is not my case !

[JC Carrillo]

Was getting "Unsupported Modules Detected: Compilation is not supported for following modules: mobile. Unfortunately you can't have non-Gradle Java modules and Android-Gradle modules in one project" - this helped me. Thanks!

File -> Settings (= STRG+ALT+S) -> Plugins -> uncheck "Android Support" JetBrains Help Page

[IulianT]

worked for me with just the deletion of .idea dir, on astudio 3.5

[Stealth Rabbi]

Does this work on only specific versions of Android Studio ?

[user_MGU]

Thank. It helped me. And the solution is pretty! :) But with: Sync Project with Gradle Files

[MohanRaj S]

What are file will configure in .gitignore, can you please give suggestions for the new project.

[djdance]

In my case I had no such a plugin, but had "Markdown plugin" marked as red incompatible, I uninstalled it and solved the problem after AS restart.

[Stuart Schechter]

1.a After selecting "Invalidate Caches/Restart" a dialog appears. Make sure to choose the "invalidate" option only and close Android studio manually. If you choose "invalidate + restart" Android studio will restart before you can complete steps 3-5.

[Redar]

deleting .idea folder and .iml file helped.

[3c71]

It worked for me. I had this error on a gradle module that was later removed but error kept being reported no matter what. Removing the module from modules.xml worked while everything else didn't.

[tir38]

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

[JCarlosR]

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).

[Neo]

@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]

@MohanRajS, all the files which generates automatically must be ignored. For example- every iml file, .idea folder, .gradle folder, build folder, .classpath, .project , .log, .apk, .aab etc.

[Rahul Tiwari]

more precisely: deleting modules.xml from .idea directory works. stackoverflow.com/a/61813520/1529129

[Afilu]

Worked for me with android studio 4.0

[Suresh Maidaragi]

Please try to add solution instead redirecting to another websites

[Nimral]

Worked for me too, needed to rebuild the project before it worked.

[hushed_voice]

Damn..worked for me.. cmd+shitf+. to see hidden folders(.idea) in mac btw

[sceee]

Received this after upgrading firebase_crashlytics package in a flutter project (Upgrade from Fabric-based to FB-based: firebase.googleblog.com/2020/06/…). This solution solved it.

[DavidUps]

It doesn't work on android artic fox, I think it's more related to Gradle but I don't find it...

this was the only solution that worked for me! of course after invalidate caches and restart.
