[FIXED] Unable to resolve class JunitAdapter

Issue

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 :

Solution

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.
