TestNG's #Test annotation not executed properly with the mvn command

Everything with the #Test annotation throws null pointer exception, regardless of the method called. I tried calling driver.findElement() and executing js script with JavascriptExecutor. Both methods ended up with a null pointer.
If I run through the IDE everything works like a charm. Otherwise, only the Before and After annotations are executed adequately

loginPage
.populateUserName("somename")
.populatePassword("somepassowrd")
.clickLoginButton();
}
}

Since still there is some uncertainty in the question, I'll try to share my thoughts around this.
If I run through the IDE everything works like a charm.
There are several ways how to run this in IDE:
Run the test class.
In this case IDE generates own testng.xml which not match the example (from the question), so it will not contain any method-selector items.
Run the testng.xml
In testng.xml there is method-selector which expects System.getProperty("env") provided.
If you run testng.xml from IDE, you have to provide somehow
System.getProperty("env") via IDE settings, otherwise you'll see org.testng.TestNGException: javax.script.ScriptException error.
If I look at testng.xml, I see method-selector, which filter tests by System.getProperty("env").
And If I look at the test:
#Test
public void successfulLogin(){
LoginPage loginPage = new LoginPage(driver);
I see no any group defined for it. So this test cannot be executed with maven command. And it's unclear how it might throw any exception.
If I look at maven command
mvn -Dwebdriver=chrome -Denv=qa test
I cannot see the arg defining which testng xml suite to execute.
I expect the command like:
mvn test -Dwebdriver=chrome -Denv=qa -Dsurefire.suiteXmlFiles="src/test/resources/tests.xml"
Expected behavior
When we execute the maven command:
mvn test -Dwebdriver=chrome -Denv=qa -Dsurefire.suiteXmlFiles="src/test/resources/tests.xml"
method-selector in testng.xml looks for methods matching the qa group.
and there are no any methods, matched this group.
But there are some configuration methods with alwaysRun = true, and they will be executed anyway.
So
#BeforeTest(alwaysRun = true)
public void testInit() {
is invoked without any tests,
and the output will be:
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 4.345 s - in TestSuite
[INFO]
[INFO] Results:
[INFO]
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
[INFO]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 11.867 s
And the test will be executed if we'll add the group:
#Test(groups= {"qa"})
public void successfulLogin(){

I've solved it. It turns out that initialising the driver with the #BeforeTest annotation is not a good idea, especially if your teardown method is marked with #AfterTest. The driver is initialised and used correctly in the first #Test method, but on the second one, the teardown method is already called and the driver becomes null. So I used #BeforeClass and #AfterClass (I might reconsider and use #Before/AfterSuite). Then I added the following configuration to the pom.xml
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.2</version>
<configuration>
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
</configuration>
</plugin>
</plugins>
</build>
Then I added the package with the tests I wanted to execute, in the testng.xml file, like this:
<packages>
<package name="path.to.tests.*"></package>
</packages>
Finally I called the mvn command using the following syntax:
mvn test -Dsurefire.suiteXmlFiles=testng.xml -Dwebdriver="chrome" -Denv="qa"
This way you don't have to call the path to the testng.xml file, but rather call it out of the pom.xml. As a side note to the last sentence, my testng.xml file is located in the project directory, along with the src folder. If you put it in another folder, I guess it will be good to set the path to this folder in the pom.xml
I hope this is understandable and it will be helpful for anyone who gets stuck with such issue.
Thank again to the others for the clues.

I am using version:
Neon.3 Release (4.6.3) of Eclipse
Natural 0.7.6 Cucumber plugin
Maven version : Apache Maven 3.6.3
Java Version : java version "1.8.0_241"
structure of the project
I have tried changing versions for java and Junit and adding Io.cucumber dependencies nothing worked.
Added java 1.8 jdk to project build path.
I have viewed all previous threads on this kind of issue.

I did not understand why you using #RunWith annotation in step def class. As cucumber will automatically take care of running it via cucumberRunner, so you can execute your test either from Runner class or via feature files(Scenario level or entire feature file) w/o using any #RunWith annotation. Probably this is the cause of your error here-See below exception:
cucumber.runtime.CucumberException:
Classes annotated with #RunWith(Cucumber.class) must not define any
Step Definition or Hook methods. Their sole purpose is to serve as
an entry point for JUnit. Step Definitions and Hooks should be defined
in their own classes. This allows them to be reused across features.
Offending class: class com.abc.StepDefs.FWFeatureTestSteps (for ex).
Also you need not to have separate junit dependency in pom, only cucumber-junit is enough as long as you want cucumber to get the job done.
Note: Don't mix io.cucumber and info.cukes, use any of them. Mixing both will also cause this very same exception.

I would recommend reconsidering using Selenium Remote Control as it is quite outdated approach which is no longer supported, current stable version of Selenium Java client is 3.141.59 and it provides WebDriver API which is a W3C Standard as of now.
Once you implement option 1 get rid of those Thread.sleep() as it's a some form of a performance anti-pattern, go for Explicit Wait instead, check out How to use Selenium to test web applications using AJAX technology for comprehensive explanation and code examples.
It's better to use a dependency management solution like Apache Maven which will automatically detect and download your project transitive dependencies. A relevant pom.xml file would be something like:

Cucumber and Selenium Error on Feature

I created a automated test scenario using selenium + cucumber on java, and when I try to execute my test nothing occur. I don't know what I did worng but I think that something happend with my feature, because exist warning on the following messages "No definition found for I try to login on facebook", "No definition found for I put my user "email"", "No definition found for I put my password "pass"" and "No definition found for validate login".

You need to add glue option to cucumberoptions with the path to the step definition classes. Use glue="com.tdd.facebook". I am not sure about this but you might want to remove the constructor in the runner RunTest.
In the LoginStps class - i_try_to_login_on_facebook() method, you are declaring another driver variable and initializing it. Thus the driver field of the class will remain null. Remove this. Also in the same method you are throwing a k. As you have implemented the step you do not need it anymore.
Also do check if all the jars are imported in the pom. I think you are missing some jars. Check the cucumber java page.

Hadoop 2.7.1 on Ubuntu 14.04 and Eclipse Local Run: java.lang.NoClassDefFoundError

I recently started learning how to setup Hadoop and have written my first application by following Hadoop: The Definitive Guide book. However, I am stuck on a step where I have to run my application locally on a small piece of data.
mvn compile
export HADOOP_CLASSPATH=~/workspace/hadoop-book-mr-dev/target/classes/com/hadoopbook/hadoop_book_mr_dev/
hadoop MaxTemperatureDriver -conf conf/hadoop-local.xml input/ncdc/micro output
I ran the commands above in the command line and exported the Eclipse workspace which contains the required classes as my $HADOOP_CLASSPATH. The last command which uses my application to analyze the data does not succeed and gives me this error:
Exception in thread "main" java.lang.NoClassDefFoundError: MaxTemperatureDriver (wrong name: com/hadoopbook/hadoop_book_mr_dev/MaxTemperatureDriver)

I have tried different folders and directories as my classpath but to no avail. Additionally, I read other similar topics and did Clean->Clean Selected Projects as well as removing the source folder from my buildpath and then add it back again but none of them are working for me.
Finally, I have also checked that I have commons-logging-1.1.1.jar and hadoop-yarn-common-2.7.1.jar as buildpath in my Eclipse. I am not sure what else to try at the moment and would appreciate it if anybody could guide me through this step by step.
Here are some additional information to help in debugging the problem. The pom.xml that the mvn eclipse step builds from:
