Exporting Gradle Project - How to include gradlew

Setting up an automated build process. Want to export the Unity project as a gradle project so that I can build in two steps (use two seperate docker images).

When Unity exports the project, there isn't a gradlew file in the project folder. How might I go about including one?

 

Our solution here is to manually copy the gradlew from the local PC into the exported gradle project in a postbuild event. We keep the gradlews in a folder with other relevant gradle scripts and do a file copy.

This sample code assumes a folder called Gradle at the root level of the project (same level as /Assets/) with all relevant gradle files.

Code (CSharp):

1. var gradlewsPath = Path.Combine(new DirectoryInfo(Application.dataPath).Parent.FullName, GradleDir);
2.             var gradleWrapperPath = Path.Combine(gradlewsPath, "gradle");
3.  
4.             foreach (var directory in Directory.GetDirectories(gradleWrapperPath, "*", SearchOption.AllDirectories))
5.             {
6.                 Directory.CreateDirectory(directory.Replace(gradlewsPath, projectPath));
7.             }
8.             foreach (var file in Directory.GetFiles(gradleWrapperPath, "*", SearchOption.AllDirectories))
9.             {
10.                 File.Copy(file, file.Replace(gradlewsPath, projectPath), true);
11.             }
12.  
13.             File.Copy(Path.Combine(gradlewsPath, GradlewName), Path.Combine(projectPath, GradlewName), true);

 

Thanks for the reply - seems like a simple enough solution. For now I am just creating a gradle wrapper after the project exports.

 

Hi,
Where exactly can I find the gradlew files on my computer?
I don't need to make a gradle export. I just want to upload the NDK Symbol files to Firebase Crashlytics.
As described here: https://firebase.google.com/docs/crashlytics/ndk-reports

@charlesJRG , How were you able to get a working gradlew file from the Unity project?

 

did you manage to do this?

 

Not yet.
I did a one time export to a gradle project to get a gradlew file.
It seems to me that this is just a generic file, I can't find anything in there that seems to be projectspecific.
So I guess I can use this file to upload the symbols.

I am currently trying to integrate the exported gradlew file (and other dependencies) in the build process.
I will update here when I have something that works.

Edit: I am trying to find the folder where I shoudld copy the gradle files.
I expected there to be a gradleOut folder, but I can't find it in the StagingArea

Here is an update:
I first forgot to put Unity back to not export a gradle project.
The gradleOut folder is at {UnityProjectPath}/Temp/gradleOut

In a postbuildprocess I copy the gradle files to that folder and use

System.Diagnostics.ProcessStartInfo

to start the command tool (cmd.exe on windows, I will have to find out what to use on Mac)

I don't know how to see if the upload of the symbols was successful though.
I will update here if I can get it working successfully.

Update 2:
I currently get a warning like this. I added the obj folder because I received an error first that said it enjoyed having a folder with that name. I provided. It did not deliver.

 WARN - Crashlytics found no object files in {UnityProjectPath}\Temp\gradleOut\obj. Is the -androidNdkOut setting configured correctly?

I don't know what kind of files it would expect in that folder.
I don't know if I can ignore this warning. It seems like it won't generate the correct symbols if the folder is empty though.

Update 3:
I managed to get something working. I can now execute

./gradlew crashlyticsUploadSymbolsDebug

correctly. It seems to update just fine.
I tested it by calling it manually. I don't know how I can check if it runs correctly as a postbuildstep though. But I imagine it does.
What I did: I just added 2 lines in the crahlytics scope in the gradletemplate.

Code (Boo):

1. // Enable Crashlytics NDK reporting
2. crashlytics {
3.     enableNdk true
4.     androidNdkOut 'src/main/jniLibs'
5.     androidNdkLibsOut 'src/main/jniLibs'
6. }

I hope it helps.

 

How did you get the crashlytics API key?

The crashlyticsUploadSymbolsDebug task is failing because it can't find the API key.

$ ./gradlew crashlyticsUploadSymbolsRelease
> Task :fabricGenerateResourcesRelease FAILED
ERROR - Crashlytics Developer Tools error.
java.lang.IllegalArgumentException: Crashlytics found an invalid API key: null.
Check the Crashlytics plugin to make sure that the application has been added successfully!

 

I think that is part of the strings.xml file
