NoClassDefFoundError: com/cloudbees/plugins/credentials/CredentialsProvider

[Jacqueline Taing]

Hi all,

I'm getting the following error during the injected test when I build my plugin:

My pom.xml has the following:

  <parent>

    <groupId>org.jenkins-ci.plugins</groupId>

    <artifactId>plugin</artifactId>

    <version>>1.554.1</version><!-- which version of Jenkins is this plugin built against? -->

  </parent>

        <dependency>

            <groupId>org.jenkins-ci.plugins</groupId>

            <artifactId>cloudbees-folder</artifactId>

            <version>4.10</version>

            <type>jar</type>

        </dependency>

Any ideas?

Thanks,

Some missing dependencies:

- https://wiki.jenkins-ci.org/display/JENKINS/Credentials+Plugin

You might need to add it as part of your pom.xml file, scope test:

https://github.com/jenkinsci/credentials-plugin/blob/master/pom.xml#L35-L36

I hope it helps

Specifically `cloudbees-folder` has

https://github.com/jenkinsci/cloudbees-folder-plugin/blob/cloudbees-folder-4.10/pom.xml#L55-L60

Since this is an `optional` dependency, it does not automatically get
included transitively in your plugin’s test classpath. If you want it,
you need to add it.

That said, it looks like a bug in `cloudbees-folder` that it has this
optional dependency yet does not behave gracefully when the dependency
is missing. Possibly it suffices for `@Extension` to be marked
`(optional=true)`. Perhaps file a bug/PR.

Thanks all! I did have to add the dependencies to pom.xml.  I added the two items below and now everything is good.

        <dependency>

            <groupId>org.jenkins-ci.plugins</groupId>

            <artifactId>credentials</artifactId>

            <version>1.8.3</version>

            <optional>true</optional>

        </dependency>

        <dependency>

            <groupId>org.jenkins-ci.plugins</groupId>

            <artifactId>matrix-auth</artifactId>

            <version>1.0.2</version>

            <optional>true</optional>

        </dependency>

Awesome!If you need them only form testing then change their scope as test
Cheers

[Jacqueline Taing]

How do you specify scope of dependency in pom.xml?

Thanks,

[Victor Martinez]

There are a list of different dependency scopes, in your case you need to add the test scope tag. 

Further details: 

- https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

If you don't need that dependency in your runtime then use that test scope.

Cheers

Thank you!
