Revisiting the conflict of lombok with java runtime compilation

问题

I am working in IntelliJ Idea, with JDK and JRE 8. The project makes use of lombok, and I would like to have code generation and runtime compiling. My aim is to produce a code that does the same task as some complicated runtime generated lambda function, to speed up the evaluation. The project makes heavy use of lombok. And I have the same issue as the one discussed here, so I know that one way around this problem is to add particular dependencies.

My question is: did there appear any other, cleaner ways around this issue, without, say, editing pom.xml? For I am in a large project developed by a team, and I don't want to interfere on such a ground level.

Now, more specifically, my code looks as a usual code for runtime compilation one finds in examples like that one:

//Create class code
StringBuilder sb = new StringBuilder();
sb.append("package foo{\n");
sb.append("    public class bar{\n");
sb.append("        public Function<Object,Object> tee {return x -> x;}\n");
sb.append("    }\n");
sb.append("}");
String code = sb.toString();
//Creating a temporary file
File flie = File.createTempFile("bar", ".java");
Writer writer = new Filewriter(file);
writer.write(code);
writer.flush();
writer.close();
//Creating compilation environment
DiagnosticCollector<JavaFileObject> diagnostics = 
    new DiagnosticCollector<JavaFileObject>();
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
StandardJavaFileManager fileManager =
    compiler.getStandardFileManager(diagnostics, null, null);
Iterable<? extends JavaFileObject> compilationUtils =
    fileManager.getJavaFileObjectsFromFiles(Arrays.asList(file));
JavaCompiler.CompilationTask task = compiler.getTask(
    null, fileManager, diagnostics, null, null, compilationUtils);
//Compiling the file
boolean success = task.call();
//Trying to extract the classes
Class clazz = Class.forName("bar");

I suppress all trys and catchs for readability. Now, when I run the code, an exception is thrown on the operator Class clazz = Class.forName("bar);. Meanwhile, the diagnostics variable shows the following message:

C:\Users\Kolya\AppData\Local\Temp\bar4319793429862999020.java:6: warning: Can't initialize javac processor due to (most likely) a class loader problem: java.lang.NoClassDefFoundError: com/sun/tools/javac/processing/JavacProcessingEnvironment

Will be thankful for any suggestions.
