Execution failed for task ':app:androidDependencies'

trying to use local maven repo on my machine without any luck.

allprojects {
    repositories {
        maven  {
            url file('/tmp/repo')


here is my dependency:

    dependencies {
        implementation('org.jitsi.react:jitsi-meet-sdk:+') { transitive = true }

getting the following error:

* What went wrong:
Execution failed for task ':app:androidDependencies'.
> Could not resolve all artifacts for configuration ':app:localDebugCompileClasspath'.
   > Could not find any matches for org.jitsi.react:jitsi-meet-sdk:+ as no versions of org.jitsi.react:jitsi-meet-sdk are available.
     Required by:
         project :app

Here is my tmp folder:

Just FYI - this working fine - all of a sudden, without any change i am getting the error. Any help would be appreciated!!
