ToolNotFoundException: jar not found.

Hi,

I'm unable to switch my Platform to Android. My console get spammed with "ToolNotFoundException: jar not found."

• "Edit->Preferences->External Tools->Use embedded JDK" is checked

• My JAVA_HOME environment variable is set to the Unity embedded JDK "C:\Program Files\Unity\Hub\Editor\2018.3.4f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\OpenJDK\Windows"

• PATH environment variable includes %JAVA_HOME%\bin
• I'm able to run "jar" from command prompt.

I'm now out of ideas.

Code (CSharp):

1. ToolNotFoundException: jar not found.
2. GooglePlayServices.ResolverVer1_1.ShouldExplode (System.String aarPath) (at Z:/tmp/tmp.mz1RZCSjez/third_party/unity/unity_jar_resolver/source/PlayServicesResolver/src/ResolverVer1_1.cs:1513)

Restarting the computer has fixed the issue. Very weird.

 

it doesn't helps for me

 

I have the same problem
Did you get it right?

 

It strange but I just have rebooted and these errors just disappeared

 

Bumping this, on 2019.1.(5f or 7f). I installed the android packages through Hub, and have all the boxes checked in Preferences->External Tools for java and android. My builds fail with the same Jar Not Found errors.

 

same... help plz

 

More info: If i click "Build" and simply save the apk locally i get the same errors in the console but the build completes and writes the APK to disk. If I have my testing phone plugged in (same phone that worked before i reinstalled my operating system) and i try 'Build and run' the build process fails almost immediately with the same errors in the console.

 

Fixed! I had to set the ANDROID_HOME environment variable to the SDK path, in my advanced systems settings on windows. I just pointed it at the unity managed copy of the SDK, which for me was

C:\Program Files\Unity\Hub\Editor\2019.1.7f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK

I also logged out and back in again to make sure the environment variable was picked up by already running programs.

Here's a guide: http://www.software-testing-tutoria.../09/set-androidhome-and-path-environment.html

 

bump

 

I had the same trouble. What I did was:
- Download jdk latest version from Oracle
- Install it
- In Unity Editor: Menu Edit\Preferences
- Uncheck "JDK installed with Unity (recommended)"
- Click on browse
- Select folder where jdk was installed. in my case C:\Program Files\Java\jdk1.8.0_231 (default installation folder)
- Ctrl+s (just in case...
- Restart editor.

It fixed the bug to me.

I hope it helps you.

 

It happens when you use embedded JDK and delete previous Unity version. JDK that is pointed by all your Unity editors and JAVA_HOME is deleted too. I changed JAVA_HOME to a new path since I had a newer Unity with Open JDK. But it didn't help, so here is how I fixed it.

Solution:
1. In Unity open Edit - Preferences - External Tools
2. Uncheck "Use embedded JDK", here you will see path to the deleted JDK
3. Browse "Program Files\Unity\Hub\Editor\(your new Unity version)\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\OpenJDK\Windows (for me Unity even changed path automatically to a newer installed version) once I pressed browse)
4. Check "Use embedded JDK", now Unity will use correct path to it
5. Copy a new path and change your JAVA_HOME to it

 

so weird error

 

Estava com o mesmo problema, no meu caso era o erro estava no endereço "C:/Program Files/Unity/Hub/Editor/2019.4.12f1/Editor/Data/PlaybackEngines/AndroidPlayer\OpenJDK" pode ver que tem uma contra barra antes do diretorio OpenJDK. Eu retirei ela e coloquei a barra correta.

 

I had the same issue when trying to download the Advertisements package. It got fixed after I just unchecked and checked again everything in "Android" In Preferences > External Tools
