Recently I tried to use Selenium for Web UI auto testing, but when running

driver.get()

java.lang.NoSuchMethodError: com.google.common.collect.ImmutableSet.toImmutableSet()Ljava/util/stream/Collector;

Following is full stacktrace

Cause

I look through the com.google.guava jar source code, and found there is com.google.common.collect.ImmutableSet class existed, but there is no toImmutableSet() method defined.

It’s because ImmutableSet.toImmutableSet() method is introduced in Guava version 21.0, while I’m using version 20.0.

Solution

My current pom.xml

<dependency>
   <groupId>com.google.guava</groupId>
   <artifactId>guava</artifactId>
   <version>20.0</version>
</dependency>

Change version to 21.0 and run

mvn install
