How to locate the Path of the current project directory in Java (IDE)?

I am trying to locate the path of the current running/debugged project programmatically in Java, I looked in Google and what I found was System.getProperty("user.id"), which didn't get me the project's path.

I know the command Environment.currentDirectory in C# gives the path of the current running/debugged project,so I am sure there must be a similar way in Java, too.

So I am asking if anyone could tell me or give me a code to how locate the path of the currently running/debugged project programmatically?

edit: i am writing plugin which loads with eclipse start. the plugin adds a button to the workbench of eclipse, with in the code of the plugin when i click the button i search for the current directory path.

my purpose is that when for example i debug a project and then click the button, a window will pop up presenting the debugged project's path, thanks

Two ways

System.getProperty("user.dir");

or this

File currentDirFile = new File(".");
String helper = currentDirFile.getAbsolutePath();
String currentDir = helper.substring(0, helper.length() - currentDirFile.getCanonicalPath().length());//this line may need a try-catch block

The idea is to get the current folder with ".", and then fetch the absolute position to it and remove the filename from it, so from something like

/home/shark/eclipse/workspace/project/src/com/package/name/bin/Class.class

when you remove Class.class you'd get

/home/shark/eclipse/workspace/project/src/com/package/name/bin/

which is kinda what you want.

Use user.dir key for get project location using java.

Code:

System.out.println("Present Project Directory : "+ System.getProperty("user.dir"));

OutPut:

Present Project Directory :C:\workspace\MyEclipse 10\examples\MySqlMavenDomain

For displaying all systems properties simply use System.getProperties();

Use Key value in System.getProperty("java.version"); for get output.

Code:

Properties properties = System.getProperties();
Enumeration<Object> enumeration = properties.keys();
for (int i = 0; i < properties.size(); i++) {
	Object obj = enumeration.nextElement();
	System.out.println("Key: "+obj+"\tOutPut= "+System.getProperty(obj.toString()));
}

For more details refer Class System

This is the new way to do it:

Path root = FileSystems.getDefault().getPath("").toAbsolutePath();
Path filePath = Paths.get(root.toString(),"src", "main", "resources", fileName);

Or even better:

Path root = Paths.get(".").normalize().toAbsolutePath();

But I would take it one step further:

public Path getUsersProjectRootDirectory() {
    String envRootDir = System.getProperty("user.dir");
    Path rootDIr = Paths.get(".").normalize().toAbsolutePath();
    if ( rootDir.startsWith(envRootDir) ) {
        return rootDir;
    } else {
        throw new RuntimeException("Root dir not found in user directory.");
    }
}

What about System.getProperty("user.dir")? It'll give you the working directory from where your program was launched.

See [System Properties][1] from the Java Tutorial for an overview of Java's System Properties.

YOU CANT.

Java-Projects does not have ONE path! Java-Projects has multiple pathes even so one Class can have multiple locations in different classpath's in one "Project".

So if you have a calculator.jar located in your JRE/lib and one calculator.jar with the same classes on a CD: if you execute the calculator.jar the classes from the CD, the java-vm will take the classes from the JRE/lib!

This problem often comes to programmers who like to load resources deployed inside of the Project. In this case,

System.getResource("/likebutton.png") 

is taken for example.

you can get the current project path use System.getProperty("user.dir")

in that method you write Key name to get your different-different paths, and if you don't know key, you can find all property use of System.getProperties() this method is return all property with key. and you can find key name manually from it.

and write System.getProperty("KEY NAME")

and get your require path.

File currDir = new File(".");
String path = currDir.getAbsolutePath();
System.out.println(path);

This will print . at the end. To remove, simply truncate the string by one char e.g.:

File currDir = new File(".");
String path = currDir.getAbsolutePath();
path = path.substring(0, path.length()-1);
System.out.println(path);

This is a code snippet to retrieve the path of the current running web application project in java.

public String getPath() throws UnsupportedEncodingException {

    String path = this.getClass().getClassLoader().getResource("").getPath();
    String fullPath = URLDecoder.decode(path, "UTF-8");
    String pathArr[] = fullPath.split("/WEB-INF/classes/");
    System.out.println(fullPath);
    System.out.println(pathArr[0]);
    fullPath = pathArr[0];
    
    return fullPath;

}

I've just used this :

System.out.println(System.getenv().get("PWD"));
