getting java.lang.NoClassDefFoundError when using AppiumDriver constructor

[MariaSoluto]

This is the error stack I get:

FAILED: AndroidApp_ReturnUserLogsIn_ValidateMainPage
java.lang.NoClassDefFoundError: org/apache/http/impl/client/HttpClients
at io.appium.java_client.ComplexFind.(ComplexFind.java:15)
at io.appium.java_client.AppiumDriver.(AppiumDriver.java:46)

At this line:
driver = new AppiumDriver(url , capabilities);

I just upgraded to Appium 1.0, Selenium 2.41. The version of the java-client of Appium is 1.2.0.

For now, you can switch to version 1.1.0 of java-client and things should be fine.
I'll figure out what's going on here.

[Jonahss]

I'm going to push as version 1.2.1, you can load that one and see if the issue is fixed.

[MariaSoluto]

It seems like version 1.2.1 isn't available yet. I have downgraded to 1.1.0 and it works now.

[Jonahss]

1.2.1 is published now, try it out :)

[MariaSoluto]

I still get the same exact error.

[Jonahss]

O.o really? Are you using Maven?

[MariaSoluto]

Yeap

[Jonahss]

Maybe try the newest version 1.3.0?

It'd be nice to get to the bottom of this issue.

I am also having trouble running tests using maven. Running tests out of IntellJ works fine, but when running with maven and 1.3.0, I still get:

@brelson Can you file your problem as a separate issue? Can you include the code which causes the error to happen?

[bjorndown]

Presently I am not sure I will -- I think it is caused by conflicting transitive dependencies. I am seeing some progress excluding some of them.
