Nullpointer exception for pico container instantion's method running maven clean test

I am getting nullpointerException while running my cucumber tests by mvn clean test.
Scenario: Run atlas # src/test/java/Atlas/Features/Atlas.feature:3
Given Go to atlas and check title # Atlas.PageObjects.AtlasPage.openAtlas()
java.lang.NullPointerException
at Atlas.PageObjects.AtlasPage.openAtlas(AtlasPage.java:12)
at âś˝.Go to atlas and check title(file:///C:/atlas%20qa/src/test/java/Atlas/Features/Atlas.feature:4)
I created WebDriverConfig.java file and I am using pico container to share this class.
Code is working until classes are in the same package but I want to separate them.
Please ask me for more information if it's needed.

Thanks to Alexey R.
Issue is resolved.
To solve this problem I had to add classes with #Before / #After annotations to glue property in CucumberRuner class:
glue = {"Atlas.PageObjects", "Atlas.common"}

The console does not show any printed output when a feature file is executed

i am trying to print the output written in the step definitions into eclipse console. but i do not see any output in the console
i have added these below dependencies into my project and i have also included "pretty" and monochrome :true in the runner class

With cucumber-jvm 4.5.0 and up, in order to see the summary statistics at the end of a run you need to explicit ask for it via the plugins you define in your runner class. If you add the "summary" (as you have already "pretty") you should be able to see again the totals of Scenarios/Steps and time it took.
This has changed via https://github.com/cucumber/cucumber-jvm/pull/1670

Is it opening the google chrome browser?.
I think your code is not reaching to the point where there are print statements, Please share your test runner and step-definition file.

AEM CQ with JPA (Hibernate)

I'm working with Adobe Experience Manager (AEM) 6.4 with Service Pack 1, and the Forms Package.
I have a lot of extended Properties/attributes, so I made a Database diagram. I don't want to save all the additional stuff in crx I want to save it in an Oracle database.
The Database diagram is complex, so I want to USE JPA (Hibernate), at minimum. If Spring would help to make it easier to use, than that would be fine for me.
I read a lot that the OSGI is working with blueprint instead of Spring, but you can combine it.
I'm really searching for an good example how to make things work with JPA and a Oracle db.
Adobe is no Help at all, they can't show an example how to work with AEM and JPA/Hibernate/Spring/blueprint.
Can anybody help me to make things working? with AEM and JPA?
I think what I need is:
persistence.xml (RESOURCE_LOCAL or JTA?)
Entity classes with Annotation #Entity and other JPA annotations
Service classes with Transaction control and maybe manager classes to submit to work with the entity classes and get result from queries, maybe I could put it all in the service classes
hibernate-osgi (dependency)
ojdbc7 for connection (dependency)
org.apache.aries.jpa.api (dependency)
But how do I have to make things happen? Nothing works. I even don't know if this is the right way.
should I use blueprint or Spring or both?
I found this Aries thing from apache.
http://aries.apache.org
And weard different samples that I don't really understand how they work.
https://github.com/apache/aries-jpa/tree/master/examples
And some OSGI sample, they look very incomplete for my situation.
https://enroute.osgi.org/tutorial/032-tutorial_microservice-jpa.html
So is there anybody with some experience with AEM and JPA?

let me describe how it is implemented on our project. We are using AEM 6.3 with SP2.
We have next dependencies in the root pom.xml:

Also we have the Hibernate config file hibernate.cfg.xml in "resources" folder of the bundle

I've found the solution and made a post here on the site.

I feel like I'm the First Guy on earth which combined AEM with JPA/Hibernate. Now I could check if it's a benefit to work with spring, to operate with the Transactions.
And those two who voted the question down, I'm sure you are from adobe --> thanks, now I feel more expert than you on your own cms, because before my post there was no solution for this problem.
Update: Maven Dependencies. If you have problems with the dependencies you have to Embed them and add the property "Embed-Transitive to true"

There are some blog posts describing how to realise JPA persistence in AEM/CQ. In using-jpa-to-write-database-applications-in-an-osgi-container-e-g-felix-or-adobe-aem-cq5 they describe how to setup a JNDI datasource with a PersistenceUnit and how to #Reference a EntityManagerFactory.

We have integrated Hibernate 5.4.5 and JPA 2.2 into Adobe Experience Manager 6.4.4 using two approaches below. Please, check https://soft-werke.com/en/archives/news-en/how-to-install-hibernate-5-4-5-jpa-2-2-in-adobe-experience-manager-6-4-4/ for more details.
Classic approach - install zip package with all embedded Hibernate dependencies in AEM Package Manager with content-package-maven-plugin. Below is an example of Maven profile which can be later excluded to avoid installing Hibernate in each AEM deployment.

P.S.
In case you don't need different versions of same dependency on AEM instance, it's better to avoid using OSGi <Embed-Transitive>true</Embed-Transitive> as it might introduce security/performance/OSGi issues - see Embedding_Transitive_Dependencies_Into_a_Mega-Bundle_With_Maven-Bundle-Plugin for details.
In case you once decide to switch to another ORM framework, it's better to prefer JPA EntityManagerFactory approach instead of Hibernate-specific SessionFactory - check https://stackoverflow.com/a/5640796/12547140.

this.craConfigImdgRepository = craConfigImdgRepository;
this.logService = logService;
}
#Override

if (result == null) {

try {

} else {

updateConfiguration(craConfigImdg);
return Optional.of(craConfigImdg);
}
} else {
return Optional.of(result);
}
}
}
And here's my JUnit Test:
public class CraConfigurationServiceProductionTest extends AbstractSpringTest {
#Autowired
private RestTemplate restTemplate;
#Value("${system.url.internal}")
private String internalUrl;
#Autowired
private CraConfigImdgRepository craConfigImdgRepository;
#Autowired
private ElasticsearchService logService;
private CraConfigurationService craConfigurationService;
private MockRestServiceServer mockServer;
private String serviceUrl;
#BeforeEach
public void setUp() {
craConfigurationService = new CraConfigurationServiceProduction(restTemplate,
internalUrl, craConfigImdgRepository, logService);
mockServer = MockRestServiceServer.createServer(restTemplate);
serviceUrl = internalUrl + "internal/api/cra/configs/";
}
#Test
public void getConfigurationSuccessful() throws Exception {
String craConfigResponse = loadResourceAsString("responses/internal/get-cra-configuration-successful.json");
mockServer
.expect(requestTo(serviceUrl + "kyivstar"))
.andExpect(method(HttpMethod.GET))
.andRespond(withSuccess(craConfigResponse, MediaType.APPLICATION_JSON));
Optional<CraConfigImdg> response = craConfigurationService.getConfiguration("kyivstar");
mockServer.verify();
assertThat(response.isPresent()).isTrue();
CraConfigImdg craConfigImdg = response.orElse(null);
assertThat(craConfigImdg).isNotNull();
assertThat(craConfigImdg.getName()).isNotNull().isEqualTo("kyivstar");
assertThat(craConfigImdg.getUrl()).isNotNull().isEqualTo("https://scoring.kyivstar.ua/rest/api/v1/scoring");
assertThat(craConfigImdg.getUser()).isNotNull().isEqualTo("user");
assertThat(craConfigImdg.getPassword()).isNotNull().isEqualTo("password");
mockServer.reset();
}
}
When I run just this test class, I get a successful result. But when I try to do clean-test-verify with the help of the maven surefire plugin, I get the error below:
Failed tests: CraConfigurationServiceProductionTest.getConfigurationSuccessful:67 Further request(s) expected leaving 1 unsatisfied expectation(s).
0 request(s) executed.
The issue is in mockServer.verify(); field.
With JUnit4 everything worked fine, and there were no errors. I tried to use #Test from JUnit4 because I have a junit-vintage-engine dependency in pom.xml, but it did not help.

According to the JUnit official documentation, there are some incompatibilities between JUnit 5 and IntelliJ IDEA. They suggest using IntelliJ IDEA 2017.3 or newer.
I even had some problems with version 2018.1 and it was resolved with the recommended additional Maven dependencies. I also had to set the junit-jupiter-api dependency version to 5.2.0 like others.
The section Build Support with Maven can be useful to configure maven-surefire-plugin.

How to connect a Java project to an AWS mysql (mariadb) instance using Lambda Functions

Since my project is on AWS and I have to connect with other AWS related instances (such as API-Gateway, for example) I am trying to use a Lambda Function to connect to a RDS instance (and I know for a fact is up and running). Running in Eclipse with the AWS plugin, in java 8. So, the idea is I code on a local Eclipse, upload the function, run it, and then, on a serverless manner, it should execute the code.
No matter what combination of code I try, or what advice I follow, I do not get a succesful connection, so I can't query the database.
With the current iteration of code I have, I get
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
I can't for the life of me figure out why I can not connect from eclipse-java-awsLambdaFunction to a mysql-aws instance. If I try to access from terminal to the database, with the same credentials, I am allowed. I have read and followed the official documentation 4-5 times already (originally I was following this, now it is slightly tweaked, and I am unsure if with this is enough for a simple connection (I have been told and read that it is!), but I wonder if there is some other way of doing it).
This is what I execute, since the plugin makes me give "A" json, even though I do not need it, I give it one like this: {"key1" : "value1"}
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import org.apache.log4j.Logger;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;
public class Adapt_LambdaConnection implements RequestHandler<Object, String> {
private static Logger log = Logger.getLogger(Adapt_LambdaConnection.class.getName());
#Override
public String handleRequest(Object input, Context context) {
context.getLogger().log("Input: " + input);
//TODO: implement your handler
Connection con = null;
try {
con = DriverManager.getConnection("jdbc:mysql://cmf6lelghjzq.eu-west-1.rds.amazonaws.com:3306/botdb", "bot", "PassWordRandom");
}
catch (SQLException e) {
e.toString();
log.warn(e.toString());
System.out.println(e + "\nSQLException");
}catch (Exception e) {
e.toString();
System.out.println(e + "\ngenericException");
}
String status = null;
if (con != null) {
status = "connection stablished";
System.out.println(status);
}else status = "connetion failed";
return status;
