package statements are missing

[lzfgnu]

I'm writing a program to format java code(variable renaming，function renaming，class renaming). the second screenshot is the input code to format, while the first screen is the output. you can see that the input contains package import statement. I want to remain those statement in the output code. Because I am just doing renaming. How can I remain those package statements ?

`
Launcher launcher = new Launcher();
launcher.addInputResource(projectPath);
launcher.getEnvironment().setAutoImports(true);
CtModel model = launcher.buildModel();
model.processWith(new FieldProcessor());
model.processWith(new FieldAccessProcessor(table));
model.processWith(new VariableProcessor());
model.processWith(new ParamProcessor());
Collection<CtType<?>> types = model.getAllTypes();

    List<CtType<?>> typeList = new ArrayList<>();
    for (CtType<?> type : types) {

        String newClassName = NameTransform.transform(Type.CLASS, type.getSimpleName());
        if (!type.getSimpleName().equals(newClassName)) {
            Refactoring.changeTypeName(type, newClassName);
        }

        Set<CtMethod<?>> methods = type.getMethods();
        if (methods != null) {
            for (CtMethod<?> method : methods) {
                String newName =
                        NameTransform.transform(Type.METHOD, method.getSimpleName());
                if (!method.getSimpleName().equals(newName)) {
                    Refactoring.changeMethodName(method, newName);
                }
            }
        }

        Set<CtType<?>> nestTypes = type.getNestedTypes();
        Queue<CtType<?>> nestTypesQ = new ArrayDeque<>();
        if (!nestTypes.isEmpty()) {
            nestTypesQ.addAll(nestTypes);
        }
        while (!nestTypesQ.isEmpty()) {
            CtType<?> nestType = nestTypesQ.poll();
            String newName = NameTransform.transform(Type.CLASS, nestType.getSimpleName());
            if (!nestType.getSimpleName().equals(newName)) {
                Refactoring.changeTypeName(nestType, newName);
            }
            nestTypes = nestType.getNestedTypes();
            if (nestTypes != null) {
                nestTypesQ.addAll(nestTypes);
            }
        }
        typeList.add(type);

    }
    for (CtType<?> type : typeList) {
        System.out.println(type);
    }
}`

Not sure to understand the issue here.
According to your screenshot you're talking about an "unused import statement", which means that one of the import is not used in your class.
Basically in your example TEST2.testT4 is not used anymore so IntelliJ informs you that this imports is useless. I guess it's related to the transformation you performed.

So in a nutshell there's nothing wrong here.

The problem is that your original input contains several classes: by default, Spoon process the file to display only one class by compilation unit.
You can change this behaviour by setting it in the environment:

launcher.getEnvironment().setOutputType(OutputType.COMPILATION_UNITS);

Thanks for replying! I tried your method just now. but how can I get the output codes.
for (CtType<?> type : typeList) { System.out.println(type); }
the code above doesn't work.
