It seems that your version of Java is too old. Make sure that you are using Java 11 or higher.

You can install it by running brew install openjdk@11

JARNBOY commented 2 years ago

I try follow install it by running brew install openjdk@11 and try running brew reinstall openjdk@11 but is show same Exception Exception in thread "main" java.lang.UnsupportedClassVersionError: idb/CompanionServiceGrpc has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Can you suggest another solution for me?

dmitry-zaitsev commented 2 years ago

Interesting, could you try brew install java?

JARNBOY commented 2 years ago

Result when run maestro test /Users/paponsupamongkonchai/MaestroYAML/flow_ios_test.yaml show same issue about version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

maciejkrolik commented 2 years ago

I had the same issue and after Java update it worked :) As I can see in the screenshot you are still using Java 8. After executing all the commands above you probably have multiple Java versions installed in the system. Changing the default one should help.

JARNBOY commented 2 years ago

@maciejkrolik You can share step by step to change version java I try follow in stackoverflow but not change default java version.

JARNBOY commented 2 years ago

Finally I found solution fix this problem by change default java version. you can see solution in this Blog(https://medium.com/miro-engineering/how-to-switch-between-java-lts-versions-8-11-and-17-on-mac-cb6717d1272)

I will show you step by step for another had same issue after you download java.dmg from website .

  1. open terminal
  2. pastebrew install java -> until download success -> ok next.
  3. paste brew install openjdk -> it's install lastest jdk
  4. check version java -version -> if you see old version in my case show version old is1.8.0._ -> ok next.
  5. paste code this for change default java 
    
# version 18
brew install openjdk@18
sudo ln -sfn /usr/local/opt/openjdk@18/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-18.jdk

version 17

brew install openjdk@17 sudo ln -sfn /usr/local/opt/openjdk@17/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-17.jdk

version 11

brew install openjdk@11 sudo ln -sfn /usr/local/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk

version 8

brew install openjdk@8 sudo ln -sfn /usr/local/opt/openjdk@8/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-8.jdk

6. when install all is success you paste this

javahome() { unset JAVA_HOME export JAVA_HOME=$(/usr/libexec/java_home -v "$1"); java -version } alias j1.8='javahome 1.8' alias j11='javahome 11' alias j17='javahome 17' alias j18='javahome 18’

7.when enter done  you paste this
when install all is success you paste this

$ j18 openjdk version "18.0.2.1" 2022-09-07 OpenJDK Runtime Environment Homebrew (build 18.0.1+0) OpenJDK 64-Bit Server VM Homebrew (build 18.0.1+0, mixed mode, sharing) $ j17 openjdk version "17.0.1" 2021-10-19 OpenJDK Runtime Environment Homebrew (build 17.0.1+0) OpenJDK 64-Bit Server VM Homebrew (build 17.0.1+0, mixed mode, sharing) $ j11 openjdk version "11.0.12" 2021-07-20 OpenJDK Runtime Environment Homebrew (build 11.0.12+0) OpenJDK 64-Bit Server VM Homebrew (build 11.0.12+0, mixed mode) $ j1.8 openjdk version "1.8.0_312" OpenJDK Runtime Environment (build 1.8.0_312-bre_2021_10_20_23_15-b00) OpenJDK 64-Bit Server VM (build 25.312-b00, mixed mode)


8. Set java_home if you never set for MacOS can select device current youcan see in (https://stackoverflow.com/questions/22842743/how-to-set-java-home-environment-variable-on-mac-os-x-10-9)

9. ok you restart device Macbook 

10. try run " maestro test {path of file yaml} " again.
