Passing test class to be run as a parameter to Maven -Dtest - maven

Question

I have 2 test classes in my project that I want to run through jenkins, each with a particular profile (because they have different set of dependencies). I tried to create a parameter "Class_To-Run" which will have the name of class to be run in the pre-steps and then executed project as:
mvn clean compile test -Dtest=$Class_To_Run -P profileUsed
which throws the following error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.21.0:test (default-test) on project SparkTest: No tests were executed! (Set -DfailIfNoTests=false to ignore this error.)
However, if a specify the name of the class to be run in the command itself (-Dtest=ClassName), the project runs successfully. Am I committing some mistake? How do I make it parameterised?
Following is the log after build fails:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.21.0:test (default-test) on project SparkTest: No tests were executed! (Set -DfailIfNoTests=false to ignore this error.) -> [Help 1]

Answer 1

Finally, I figured it out. As I said in comments above that the variable ("Class_To_Run") was not being expanded to its value while the maven command was being executed by jenkins. The problem was that I had declared the variable in execute shell part in Pre Steps of jenkins job configuration. The parameters that you create in the general step of jenkins job are only accessible in the build step.
