Weblogic server guava NoSuchMethodError

Question

I'm trying to deploy a web project with a war file on the weblogic server. But I'm getting an error like above,

java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concurrent/Executor;
    at com.google.common.eventbus.EventBus.<init>(EventBus.java:138)

I tried lastest and oldest versions of guava. In the oldest versions I got eventbus error (no defined this method in the old versions). In the newest versions I got the same error again.

How can I solve this problem?

EDIT: It runs clearly in my editor (IntelliJ), when I try to run it on a weblogic server I get this error in deployment.

UPDATE:

I just added a weblogic.xml file like above in my WEB-INF path. No need any other configurasyon. The problem resolved for me thanks to @luc14n0

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xsi:schemaLocation="http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">

<container-descriptor>
    <prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

</weblogic-web-app>

I think no, because it runs clearly in my editor. It does not work on weblogic server in deployment. — stephan, May 10 '17 at 06:33
which means that the classpath is being built differently between your editor and deployment. — Yosef Weiner, May 10 '17 at 07:57

Weblogic 12c (12.1.3) ships with its own Guava dependency at Oracle/Middleware/Oracle_Home/wlserver/modules/com.google.common_1.2.0.0_11-0-2.jar

By telling WebLogic you prefer to use your own version, you avoid the conflict where it loads the wrong library.

In case of an EAR, add the following to application.xml:

<prefer-application-packages>
  <package-name>com.google.common.*</package-name>
</prefer-application-packages>

In case of a WAR, add the following to weblogic.xml:

<container-descriptor>
  <prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

@enes it goes into _src/main/webapp/WEB-INF/weblogic.xml_ – Luciano van der Veekens May 11 '17 at 06:36
