Trove4j library cannot be resolved

Question

I'm getting the following error when trying to compile my app:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':myProject'.
> Could not resolve all files for configuration ':myProject:classpath'.
   > Could not find org.jetbrains.trove4j:trove4j:20160824.

It appears a library the IDE needs is missing?

Answer 1

this issue can be resolved by adding jcenter() as a repository in the buildscript section.

buildscript {
  repositories {
     jcenter()
  }

  dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0-beta2'
  }
}

Answer 2

Additional to Snicolas' answer:

If you have something like:

allprojects {
    repositories {
        mavenCentral()
        google()
        jcenter() //also add it here!!!
    }
}

In your build.gradle file; also add it there.

Answer 3

Since jCenter will close in May, you should change root/build.gradle so:

buildscript {
    repositories {
        google()
        gradlePluginPortal()
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        // org.jetbrains.trove4j:trove4j:20160824.
        gradlePluginPortal()
    }
}

See also https://stackoverflow.com/a/66168563/2914140 to add libraries not included in Maven.

Now we can build apk without errors.

Answer 4

If you're seeing this error after May 1st 2021, it's probably because jcenter is shut down. It's needed by the Android Gradle Plugin (AGP). Google devs have said they're using a newer version of the library that can be got from mavenCentral() as of AGP 7 and hoping to backport that into AGP 4.2 and 4.1. So first of all, try and upgrade to AGP 7. And if I haven't edited this post with updates, check to see is it in any lower AGP versions.

But if you can't upgrade AGP, as of initial time of posting (February 2021), the only repo I could find with the trove package is on pentaho, which seems to be owned by Hitachi so I presume it's safe.

buildscript {
   repositories {
         maven { url "https://nexus.pentaho.org/content/groups/omni" }
   }

   dependencies {
         classpath 'org.jetbrains.trove4j:trove4j:20160824'
   }
}

This is NOT an ideal solution. This repo could be intended to be private for all I know. Look for a better answer that might be posted after me.
