java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.directExecutor()

I’ve been grappling all day with java.lang.NoSuchMethodError issues, presumably due to Guava conflicts and some strange interaction with maven. I’ve also tried with different version of grpc-* and the protoc plugin, to no avail.

Relevant parts of my pom.xml:

>       <groupId>io.grpc</groupId>
>       <artifactId>grpc-netty</artifactId>

Here is also the relevant output of mvn dependency:tree -X:

Please answer these questions before submitting your issue.

What version of gRPC are you using?

1.0.3 (also tried 1.1.2)

What JVM are you using (java -version)?

java version “1.8.0_101” Java™ SE Runtime Environment (build 1.8.0_101-b13) Java HotSpot™ 64-Bit Server VM (build 25.101-b13, mixed mode)

What did you do?

If possible, provide a recipe for reproducing the error.

(See above for pom.xml)

I then followed the HelloWorld example to build a client and a server. In a Junit test case, the client simply invokes the rpc via a blockingStub.

What did you expect to see?

No errors.

What did you see instead?

With 1.0.3

 java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concurrent/Executor;

 	at io.grpc.internal.ManagedChannelImpl.newCall(ManagedChannelImpl.java:535)
 	at io.grpc.stub.ClientCalls.blockingUnaryCall(ClientCalls.java:133)

With 1.1.2

For me instead of Upgrading the Guava to latest ver, I had to exclude Guava JDK5 dependency in configurations to fix the error. Did something like below

configurations {
        all*.exclude group: 'com.google.guava', module:'guava-jdk5'
    }

@MarcMagnin The problem is that you have an older version of guava somewhere on your classpath. Can you print out your deps? It should be something like ./gradlew my-project:dependencies.
