Store information about method parameters (usable via reflection) in intellij 13

Question

Does anyone know of an equivalent for Eclipse 4.4's Store information about method parameters (usable via reflection) compiler property in Intellij Idea 13 (or older, but I doubt it would be available)?

Edit: This link shows how to do it with maven, but I would still like to know how it's done in Idea Run Eclipse with M2 Maven build ignores "Store method parameter names" definition

Answer 1

• Go to edit Settings (Projects setting actually) Alt+Ctrl+S
• Search for Java Compiler
• Add the "-parameters" option in the compiler window. This should do the trick
  NOTE: I tried it with JDK 8 version 1.8.0 and it DIDN'T WORK. JDK 8 version 1.8.0_05 works.

Try this to validate. I have copied it from the article.

import java.lang.reflect.Method;
import java.lang.reflect.Modifier;
import java.lang.reflect.Parameter;

import static java.lang.System.out;

/**

public class Main {
    private static void displayParametersMetadata(final String className) {
        try {
            final Class clazz = Class.forName(className);

            // Get all class's declared methods (does not get inherited methods)
            final Method[] declaredMethods = clazz.getDeclaredMethods();
            for (final Method method : declaredMethods) {
                writeHeader(
                        "Method " + method.toGenericString()
                                + " has " + method.getParameterCount() + " Parameters:");
                int parameterCount = 0;
                final Parameter[] parameters = method.getParameters();
                for (final Parameter parameter : parameters) {
                    out.println(
                            "\targ" + parameterCount++ + ": "
                                    + (parameter.isNamePresent() ? parameter.getName() : "Parameter Name not provided,")
                                    + (isParameterFinal(parameter) ? " IS " : " is NOT ")
                                    + "final, type " + parameter.getType().getCanonicalName()
                                    + ", and parameterized type of " + parameter.getParameterizedType()

                }
            }
        } catch (ClassNotFoundException cnfEx) {
            out.println("Unable to find class " + className);
        }
    }

    private static void writeHeader(final String headerText) {
        out.println("\n==========================================================");
        out.println("= " + headerText);
        out.println("==========================================================");
    }

    /**
     * Indicate whether provided Parameter is final.
     *
     * @param parameter Parameter to be tested for 'final' modifier.
     * @return {@code true} if provided Parameter is 'final'.
     */
    private static boolean isParameterFinal(final Parameter parameter) {
        return Modifier.isFinal(parameter.getModifiers());
    }

    public static void main(final String[] arguments) {
        displayParametersMetadata("TestProperties");
    }
}

And the test class:

import java.util.List;

/**

 * User: zpontikas
 * Date: 7/10/2014
 * Time: 17:02
 */
public class TestProperties {

    public String getSomeStringValue(String thisIsAProperty) {
        return thisIsAProperty;
    }

    public static List<Integer> getSomeLists(final List<Integer> anotherProName) {
        return anotherProName;
    }

    public void manyProperties(final String onePropertyString,final int anotherIntProperty, final boolean thisIsBool) {

    }
}
