Intellij Idea - Java program doesn't work properly after building jar

I have a weird problem with java - I am programming in Intellij Idea, I am using this little code to make basic authorization to site

        String authString = name + ":" + password;
        byte[] binaryData = authString.getBytes();
        String authStringEnc = new String(Base64.encodeBase64(binaryData));
        URL url = new URL(webPage);
        URLConnection urlConnection = url.openConnection();
        urlConnection.setRequestProperty("Authorization", "Basic " + authStringEnc);
        InputStream is_auth = urlConnection.getInputStream();
        InputStreamReader isr = new InputStreamReader(is_auth);

This code worked for some weeks, but I continued writing my program. Then yesterday I saw that - program works when I click run in Intellij, but when I start a .jar file, this line cannot be done:

        String authStringEnc = new String(Base64.encodeBase64(binaryData));

I don't know why, but program stops when doing this line. But when I click run or debug in Intellij, everything is working.

Btw. I am using this library for encodeBase64:

        import org.apache.commons.codec.binary.Base64;

If you don't know why it isn't working, maybe you can share with me idea to make a basic authorization to site. Thanks in advance.

The answer is: I only had to refresh jar artifact. I deleted old artifact and created it again, after this everything is working well.

You need to add the Apache Commons Codec jar to your classpath when you run the jar file. You should make sure that any other jar files/libraries that you have added in IntelliJ are also on the classpath.

You should use logging in order to research your stacktrace. Probably you have some ClassNotFound exception or something similarly obvious.
