For fixing this issue from Eclipse:

1) Add below dependency in Maven pom.xml and save the pom.xml file.

<!-- https://mvnrepository.com/artifact/com.thoughtworks.xstream/xstream -->
<dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.3.1</version>
</dependency>

2) Go to project >> Maven >> Update Project

select the project and click OK.

3) Optional step, if it's not resolved till step 2 then do below step after doing step-1

Go to project >> Maven >> Update Project >> check in the checkbox 'Force Update of Snapshots/Releases'

select the project and click OK.

I had the same error and running mvn install -U and then running mvn install worked for me.

Answer 3

If you're unsure what is inside your local repository, I recommend to fire a build with the option:

-Dmaven.repo.local=localrepo

That way you'll ensure to build in a cleanroom environment.

Answer 4

If you are using eclipse IDE then :

• Select Project.

• Press alt+F5, window for Update Maven Project will pop up.

• Check - Force Update of Snapshots/releases and click OK.

If Using Intellij IDE

• go to settings/Maven
• check Always update snapshots

I ran into this recently and running the following fixed all the problems

mvn -fae install

Answer 6

mvn clean install -U

-U means force update of snapshot dependencies. Release dependencies can't be updated this way.
