java.lang.NoSuchFieldError: INSTANCE Exception While Running Appium Android Test

Question

I'm working with an Appium Android Test. I didn't have any problems with my test and it was working well. After few weeks, I tried to run it again (without any changes) and now I get the following error:

java.lang.ExceptionInInitializerError

Current POM.xml file dependencies:

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-server</artifactId>
        <version>2.48.2</version>

        <groupId>io.appium</groupId>
        <artifactId>java-client</artifactId>
        <version>2.1.0</version>
    </dependency>

Also here's setUp:

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("appium-version", "1.4.13");
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("deviceName", "Android Emulator");
capabilities.setCapability("platformVersion", "4.3");
capabilities.setCapability("appPackage", "<app_package>");
capabilities.setCapability("appActivity", "<app_activity>");
driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

(I get the error in the last line while debugging)

Once again: I didn't have this error and I didn't change anything.

Edit: I've upgraded 'java-client' and then I got the following exception:

java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing

And then I've added hamcrest-core jar file to my project. Now I get the following exception:

java.lang.NoSuchFieldError: INSTANCE

This is a dependency issue caused by http request,

Two reasons, may be ur referring more than one http-jar in ur class path -remove and keep only one

or there is no http jar to perform http req- add http core jar something like,

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>3.6.3.Final</version>
</dependency>
