I am trying to setup Fitnesse in my project but I am facing some issues with Guava jars This is how my pom.xml looks like:
<dependencies>

I am using the maven-classpath-plugin to set up the classpath in Fitnesse. This plugin transitively uses org.sonatype.sisu:sisu-guava:jar:0.9.9:runtime jar. And I also need the Guava jar for my project.

This is the error I get when I try to bring up the fitnesse server:

Now if declare the Guava dependency after the maven-classpath-plugin, then I do not run into this issue, however my unit tests and integration tests fails with MethodNotFoundException and if I declare the Guava dependency above maven-classpath-plugin then the fitnesse server won't come up with the error as shown above.
I see a similar issue Drools 6 sisu-guava conflicts with guava
Any suggestions or work-around would be really helpful.
EDIT: Found out an easier solution - I added the following dependecy in my pom.xml:
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-embedder</artifactId>
<version>3.5.0</version>
<scope>runtime</scope>
</dependency>
which stops the transitive download of sisu-guava. Now both the tests and the fitnesse server works
回答1:
This seems very similar to Fitnesse Maven Classpath error. Use one of the two approaches I mention there to deal with dependency conflicts between the libraries for the wiki and the fixtures running your tests.
