I'm working on a small project for an Android lesson and when I tried to build this error occur.

> Task :app:mergeReleaseResources FAILED
*UserFile*\.gradle\caches\transforms-3\23d9fa9961c0d98e61467ef24b5c00c7\transformed\recyclerview-1.2.1\res\values\values.xml:9:4: <item> inner element must either be a resource reference or empty.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeReleaseResources'.
> A failure occurred while executing com.android.build.gradle.internal.res.ResourceCompilerRunnable
   > Resource compilation failed. Check logs for details.

I've try to Clean Projet / rebuild, I tried to rewrite or to remove the file in question, the error still occur but on some other file (for the part where I remove the file).

I've also reinstalled my Android Studio and files.

And I've also search around on StackOverflow but since I don't really get where it come from, it's hard for me to make an effective search.

You can find the code there : https://github.com/Ulkan/OC_MaReu

1. Try Invalidate caches/ Restart.
2. And if you mention dependencies version in like this 'com.google.android.material:material:1. ' remove and put full version like this 'com.google.android.material:material:1.4.0'.

CodePudding user response：

I saw your code it is running perfectly just change your res/values/ids.xml file.

resource type id must not have a value

ids.xml

<item name="item_participant" type="id">participants</item>

to

 <item name="item_participant" type="id"/>
