Guava version 16.0 being used during runtime even though 18.0 is used during compile time - spring-boot

Question

I am trying to run a project in wildfly. Following is the guava dependency version. I tried including 18.0 in the dependency management but it still uses 16.0. Been struggling with this for entire day, googled a lot but no solution on this.
Here is the stack trace

Answer 1

Reviewing the dependency called archaius-core 0.7 5 currently is using guava version 16.0 then if you want to use guava version 18.0
You need to add the dependency by following way:
<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>18.0</version>
</dependency>
I think it is an issue of version typo when packing the jar what you are having.

Answer 2

It reminds me the class loading issue when I work with Glassfish4 long time ago. From the docs , the classes will first load from the following order before loading from the lib in the WAR :
(1) System Dependencies - These are dependencies that are added to the
module automatically by the container, including the Java EE api’s.
(2) User Dependencies - These are dependencies that are added through
jboss-deployment-structure.xml or through the Dependencies: manifest
entry.
It also mentions that the dependencies in (1) can be excluded through by the use of jboss-deployment-structure.xml.
And from this , jboss-deployment-structure.xml should be placed inside /WEB-INF/ and can prevent the server from automatically adding some dependencies by :
<jboss-deployment-structure>
<!-- Exclusions allow you to prevent the server from automatically adding some dependencies -->
<exclusions>
<module name="com.google.guava" />
</exclusions>
</jboss-deployment-structure>
Actually I don't know how to find the module name of the Guava module, I just search the docs and Github and found there is a one called com.google.guava .
I am also not sure it will work or not. But hope to give you some direction .Good luck.
