kuldeep_yadav March 28, 2023, 4:51am 4

@rahul_vakhariya is this resolved?

Namratha1 March 28, 2023, 6:03am 5

I Too have same issue

ido_oserovitz March 28, 2023, 6:35am 6

which java-client version do you use?

developer March 28, 2023, 8:23am 7

I got this issue on latest java-client (8.3.0)

ido_oserovitz March 28, 2023, 8:37am 8

ok, great.
Do you know to tell which selenium-api version you use?
look at the jar file selenium-api-4.8.2.jar or similar…
If you use selenium 4.8.2 or above then, please checkout my workaround here(you can try it anyway if you want, assuming you use maven): https://github.com/appium/java-client/issues/1872#issuecomment-1484017595

If you will find it beneficial please write here so others will know as well.

I have the same issue and I can not just use the workaround posted by @ido_oserovitz since this is failing in our Azure pipelines as well. Any other suggestion around this issue? Im using java-client 8.3.0 and the selenium version that java-client 8.3.0 uses which is probably 4.8.2 or above.

ido_oserovitz March 28, 2023, 11:13am 10

We manage our pipelines using Jenkins and running the tests on a remote VM. I connected to the machine and the workaround solved it. If you have a similar situation and you can connect to the machine which you run your tests on, it should work as well.

Hopefully this will fix the issue https://github.com/appium/java-client/issues/1872#issuecomment-1484017595

Below solution solved my problem
Solved it by going to $HOME/.m2/repository/io/appium/java-client/8.3.0 and adjusting the file: java-client-8.3.0.pom . Changing all selenium related dependencies’ version tag from: <version>[4.7.0, 5.0)</version> to <version>[4.7.0, 4.8.2)</version> to eliminate incompatible 4.8.2 selenium version.

I faced same issue even i set all configuration proper and also add .m2 repository but now i have solved this issue by adding following lines of code if you still facing issue after set configuration also then just add below one line of code in AppiumServiceBuilder:

.usingDriverExecutable (new File (“C:\Program Files (x86)\nodejs\node.exe”));
