How to resolve "Could not create an instance of type org.gradle.initialization.DefaultSettings_Decorated." for InMobi Unity Mediation Plugin

12.3k Views Asked by chethanv77777 At 10 April 2025 at 06:30

I am trying to implement google-admob mediation and currently working on Integrating InMobi ads. I followed all the steps as per https://developers.google.com/admob/unity/mediation/inmobi .I was able to create the Account ID and Placement ID in the inMobi website . I successfully was able to configure AdMob ad unit in my admob account.

The problem is in the 3rd step of the process which is "Import the InMobi SDK and adapter". I extracted the latest version of Google Mobile Ads mediation plugin for InMobi from this link https://developers.google.com/admob/unity/mediation/inmobi#inmobi-unity-mediation-plugin-changelog .

But while performing this step Assets > Play Services Resolver > Android Resolver > Force Resolve , I am getting the following "Android Dependencies , Resolution failed" error. I am attaching the screen shot and the log file below. I tried to change the version of the InMobi Unity Mediation Plugin some 5 times,but all the time it keeps failing. I changed to stack trace to full and understand but still can't really figure out what to do.

For inMobi ad mediation for unity there is no video on youtube also. Please help me to figure out the solution for this problem.

In my case switching Edit->Preferences->ExternalTools->JDK from default OpenJDK to manually installed old Oracle JavaSE8 JDK helped.

**beuzel** · Answer 2

I had the same error message and tried a lot of things to fix it. Finally updating Java from jdk-17 to jdk-19 fixed it. I also updated the environment variables

JAVA_HOME=C:\Program Files\Java\jdk-19

and

PATH=C:\Program Files\Java\jdk-19\bin

Note that the PATH variable actually contains many more paths from other programs on my system. A windows logoff and login is required for the changes to take effect.

**Erçin Dedeoğlu** · Answer 3

It's a bug that has existed for years. Maybe we've been dealing with this since the 2017 release. But unfortunately, it is not even clear what Unity is doing about it.

To solve: Edit->Preferences->External Tools

In the window that opens, you must remove the checkboxes at the bottom and give the same paths! It's ridiculous, but yes, it's true!!!

Good luck, we need it.

I did the following three things.

Followed Erçin Dedeoğlu instructions. (Nothing Happened)
Had JDK 21 and downgraded to JDK 19. (Nothing Happened)
Toggled the "Stop Gradle Daemons on exit" option. (Worked)
