getting a "NoSuchMethodError" exception when trying to start firefox via selenium 3.4.0

Question

i am using selenium 3.4.0 in java.

the line "new FirefoxProfile()" produces the error which reads: "com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)V"

how can i resolve this error ??

Answer 1

If you have any legacy Guava library added to your build path, remove it.

Comments

i've removed all guava references but the 21.0 version, still no luck

Okay, checkArgument has the first parameter to be passed as boolean, IInd one string and Object is optional.

So, add boolean condition first and then any String and Object.

Hope that helps!

the method is in the package "com.google.common.base.Preconditions" which obviously i cannot change, so how can i "add boolean condition first and then any String and Object" ? is there a way to update the google code ?!?
