Unable to resolve class JunitAdapter - jenkins

Question

I wrote a test where I am importing a class from package com/intel/epgsw/JunitAdapter.groovy
When I try to run the test, I get this error:
[ERROR] Failed to execute goal org.codehaus.gmavenplus:gmavenplus-plugin:1.5:testCompile (groovy) on project jenkinsfile-test-shared-library: Error occurred while calling a method on a Groovy class from classpath. InvocationTargetException: startup failed:
[ERROR] src/test/groovy/CloneTestSpec.groovy: 3: unable to resolve class src.com.intel.epgsw.JunitAdapter
[ERROR] # line 3, column 1.
[ERROR] import com.intel.epgsw.JunitAdapter
[ERROR] ^
Test file is present in: src/test/groovy
Class that needs to be imported: com/intel/epgsw/JunitAdapter.groovy
My test file is CloneTestSpec.groovy
Here is the tree :
src
│   ├── com
│   │   └── intel
│   │   ├── epgsw
│   │   │   ├── TestResultEnum.groovy
│   │   │   ├── **JunitAdapter.groovy**

Your directory layout is chaotic. Please move all your test classes into the src/test/groovy base folder. There, you create a directory structure according to your package structure. For example (I cannot say for sure without seeing the package declarations in each file), assuming that
all application classes are Java classes,
all test classes are Groovy classes and
all classes are in the exact same package com.intel.epgsw:
src
main
java
com
intel
epgsw
ApplicationClassA.java
ApplicationClassB.java
test
groovy
com
intel
epgsw
TestResultEnum.groovy
JunitAdapter.groovy
FooBar98.groovy
CloneTestSpec.groovy
If any of my above assumptions are false, you need to adjust the directory structure accordingly. But your chaotic directory layout with 3 different base directories causes the trouble you are facing. Please do learn some Java, Groovy and Maven basics, especially the Maven standard directory layout.
