Java runtime compilation fails

Question

For our project we needed to compile few class files during run-time, we have started to use JavaCompiler class. Everything works fine in Eclipse however when we tried to build (Maven) and deploy we are getting "package does not exist" error.

Code first:

Files.walk(Paths.get(inputTestcaseFolder))
    .filter(Files::isRegularFile)
    .filter(path -> path.toAbsolutePath().toString().contains(".java"))
    .forEach(fileList::add);

for (Path p : fileList) {
    System.out.println("Test Compiled : " + p.getFileName().toString());
    JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();           
    compiler.run(null, null, null, p.toString());
    }

Also tried referencing the class path still the same issue

JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
                   StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null);
                   List<String> files = new ArrayList<>();
                   files.add(p.toString());
                   Iterable<? extends JavaFileObject> compilationUnits1 =
                   fileManager.getJavaFileObjectsFromStrings(files);                       
                   optionList.addAll(Arrays.asList("-classpath",System.getProperty("java.class.path")));
                   compiler.getTask(null, fileManager, null, optionList, null, compilationUnits1).call();
                   fileManager.close();

Jenkins Job configuration:

Build Goal and Options:

-e -X clean compile dependency:copy-dependencies exec:java

Tried Still the same error --> optionList.addAll(Arrays.asList("-classpath",System.getProperty("java.class.path"))); compiler.getTask(null, fileManager, null, optionList, null, compilationUnits1).call(); fileManager.close(); — Jyothishwar Deo, May 12 '16 at 21:20
Is there really a hyphen missing at the Maven option `Dexec...`? — Gerold Broser, May 12 '16 at 21:40
