Bug JAVA_HOME error when import Dependency Resolver

When importing Ads Mediation (Or IronSource), it says that you must install the Mobile Dependency Resolver. After installing it, when I click "Dependency Resolver / Resolve" it gives a problem of "unity java_home environment references to directory", looking for JAVA it in a directory of an old unity installation (which is uninstalled) that no longer exists. I have updated the JAVA_HOME environment variable to the new ones, also in unity/preferences/external tools all the sdks,... and it still gives the same error-

I use Unity 2022.2.12 and it looks for JAVA_HOME in the uninstalled 2021.3.15f1...

I have got the same bug. The only difference is that it tries to read the 2019.3.0b5 file.
Unity 2022.2.11 with "IronSource_IntegrationManager_v7.3.0.1"

I tried everything from here:
https://stackoverflow.com/questions...environment-references-a-directory-in-unity3d
https://answers.unity.com/questions/1638828/how-to-set-java-home-using-openjdk.html

Even in a new 2022.2.15f1 project it is the same.

 

Facing same issue with iron source mediation adapter installed from following link.

1. Download Unity Plugin Version 7.3.0.1

The dependency resolver is trying to use 2019 unity version JAVA_HOME in unity 2021.3.23
It is unity bug or iron source bug ?

Even tried to make build from iron source demo project and same issue is coming.

 

No help from IronSource or Unity.
Now AdMob works without problems.

 

I'm facing the same issue, JAVA_HOME pointing to a wrong path, Have tried everything, no luck, using Unity 2022.2.14 with Facebook SDK, Firebase and Ironsource LevelPlay, cannot resolve android dependencies because of this.

 

I resolved the problem of JAVA_HOME, Mediation and "Gradle build failed". This problems are mostly related to existing old Unity configuration. I have Unity 2021.2.26f1, after migrated to 2022.3.0f1 then having Android compile problem. Later, found solutions below.

1. Before you migrating to new Unity version, is very important to ensure current version ( eg. 2021.2.26f1 ) the Preferences > External Tools > Android settings are intact, no external JAVA path but only Unity supported path for Android JDK, SDK, NDK and Gradle. Do a backup of projects and do not uninstall existing Unity version ( eg. 2021.2.26f1 ) until all projects converted are working fine.

2. Click “Copy Path” button, untick the "...Installed with Unity (recommended)" checkbox, click “Browse” button and paste the copied path info then tick the "...Installed with Unity (recommended)" checkbox again so both tick and untick path are the same. It is very important to stick to the Unity supported path otherwise JAVA_HOME, Mediation errors may occur.

3. Remove depreciated line such as “android.enableR8=“ under gradleTemplate.properties file to avoid gradle compile error.

4. Remove library components or packages that are not part of the project, I have no problem compile for Android with Mobile Dependency Resolver installed, but I removed it as not required in my project.

5. Now, do an Android compile on current Unity version ( eg. 2021.2.26f1 ) to ensure error free.

6. If statement 5 is clean and fine then you may open the project with new Unity version ( 2022.3.0f1 ), the new Unity Editor will prompt for upgrading and handle conversion automatically to land the project at right configuration.

Hopes, this help.

 

Same issue - actually scrapping ironsource until Unity gets that package as seamless as their own singluar intergration.

I've got the latest JDK installed, with Unity doing that installation and pathing. Yet it says it's directing to a 2020.1.5f version of Unity instead of the 2022.5.8f version.

Frustrating because it pops up every play instance and reload..

 

I guess this error appears when you have any google sdk present in your project.
Fix :
1. In your unity Preferences (Edit -> Preferences) there is a JDK path, copy it.
2. Open Environment variables in windows. Look under "System variables" for a variable name "JAVA_HOME" then Click Edit. (If not present Click Create).
3. write variable name as "JAVA_HOME" and in variable value paste the JDK path you copied. and press OK.
4. Restart unity.
And it should work Fine!

 

How can i do it on Mac M1 ?

 

still doesnt work for me,,,, anyone who found another solution

 

Damn, that's weird my in my case

Resolver error is:


but I am sure that my env setup is correct (already restarted the PC):


Any ideas how to fix that?

 

Can't believe this bug is still on the run... each time i update it comes back, and each time i need something different to fix it...

EDIT: Seems to be a project specific problem this time...
