Gradle build for Android in Unity fails, saying that it could not find intellij-core.jar

So thats what I have tried:

  • Building different projects (same thing)
  • Reinstalling sdk, jdk, and Unity Editor (newbie gotos)

I have also found very similar problem from today: Android Studio - Could not find intellij-core.jar yet the only gradle.build file that I found was the one generated with Unity in Temp folder that overwrites itself after every build start.

Unity 2018.2.13f1, Windows 10 x64, Fresh Android Studio 3.2.1, jdk1.8.0_192

Here is a console log:
Short

A problem occurred configuring root project 'gradleOut'.
> Could not resolve all files for configuration ':classpath'.
   > Could not find intellij-core.jar (com.android.tools.external.com-intellij:intellij-core:26.0.1).

Here's the only solution that worked for me since I'm behind a proxy.

  1. Go to the .gradle folder (default is under C:\Users\<name>\).
  2. Create a file called gradle.properties under this folder.
  3. Add the following:

#http proxy setup
systemProp.http.proxyHost=<your proxy URL>
systemProp.http.proxyPort=<your proxy Port>
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost

#https proxy setup
systemProp.https.proxyHost=<your proxy URL>
systemProp.https.proxyPort=<your proxy Port>
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost
  1. Reopen unity and build !

Here's what worked for me, as reported here:

  1. Go into the Player Settings
  2. Under Publishing Settings tick the box for Custom Gradle Template (Unity then creates a build.gradle template for you)
  3. The template is in Assets > Plugins > Android > mainTemplate.gradle
  4. Open that file in something like Notepad
  5. Change ONLY THIS:

    repositories { jcenter() google() } to repositories { google() jcenter() }

  6. Save the file then try the build again. Not a perfect solution but it should work until Unity/Android fixes the issue. I'm not sure whether this can become undone by upgrading Unity, but I do know that it has to be done per project.
