Unable to resolve class - Groovy junit testing using maven - intellij-idea

Question

I am trying to create groovy tests where i use other methods from other Groovy scripts. Whenever i run mvn test i get unable to resolve class error, referring to the illegal import from another groovy script.
This is the testclass that I've written :
import jenkins_methods.gitMethods
import org.junit.Test
class GitMethodsTest extends GroovyTestCase{
GitMethodsTest(){
}
def gitMethods = new gitMethods()
#Test
void testGetDvhBranches(){
try{
gitMethods.getDVH_branches()
}
catch(Exception e){
println e
}
}
}
gitMethods.groovy
package jenkins_methods
// src/jobMethods
import dvh.util.AnsiColorDefinition
import jenkins_methods.fileMethods
String getGitDVH_BranchPath_flash() { return '/git-repository1/git/dvh/branches/' }
String dvhBranchNull() { return 'feature/DV-null-repo' }
String getDVH_branches() {
gitURL_DVH= "censored_url"
String response = sh returnStdout: true, script: "git ls-remote -h ${gitURL_DVH()}"
def branches = response.replaceAll(/[a-z0-9]*\trefs\/heads\//, ',')
branches = branches.substring(1, branches.length()).replaceAll("\n", "").replaceAll("\r", "")
return branches
}
}

The jenkins_methods package contains various groovy scripts that are necessary for the Tests to become relevant.
Structure of the project is as following :
-src
-test
-groovy
-GitMethodsTest.groovy
-jenkins_methods
-gitMethods.groovy
This is the error that i get when i run mvn test
[ERROR] Failed to execute goal org.codehaus.gmaven:gmaven-plugin:1.5:testCompile (default) on project jenkins-jobs: startup failed:
[ERROR] /C:/Users/jenkins-jobs/src/test/groovy/GitMethodsTest.groovy: 3: unable to resolve class jenkins_methods.gitMethods
[ERROR] # line 3, column 1.
[ERROR] import jenkins_methods.gitMethods
[ERROR] ^
[ERROR]
[ERROR] 1 error
How do i solve this problem?
