java.lang.NoClassDefFoundError: org/eclipse/core/runtime/Plugin - eclipse

I am using eclipse Kepler.
Version: Kepler Service Release 1
Build id: 20130919-0819
I installed Drools plugin and created a maven project that I converted to a
drools project.
( Could figure out how to create a maven enabled drools project directly )
I then create a new Drools project from the Drools menu, and choose to
create sample files, rules, test classes etc. Copy those file to my maven
drools project.
But when running the DroolsTest.java I get ..
java.lang.NoClassDefFoundError: org/eclipse/core/runtime/Plugin
here is my pom.xml :

You need to add eclipse-core lib in your dependencies
<dependency>
<groupId>org.eclipse.core</groupId>
<artifactId>org.eclipse.core.runtime</artifactId>
<version>3.7.0</version>
</dependency>


<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-eclipse-batch</artifactId>
<version>2.1.5-03</version>
</dependency>
Add this as your dependency. Your issue will be resolved.

"target" subdirectories in package explorer in recent eclipse (at least 4.13 + maven 3.6.x)

So in Eclipse 4.13 (and maybe a few versions before) with embedded maven 3.6.x, when I open a simple, almost empty, maven project, it shows me these non existant subdirectories in project explorer :
target/generated-sources/annotations
target/generated-sources/test-annotations
If I remove them from source directories (in project > properties > java build path), eclipse creates these directories and add them as sources again, so I guess it comes from some maven plugin conf somewhere.
How do I get rid of these 2 directories display when I don't have use of them ?
And since this problem probably comes from a combination of maven 3.6 + Eclipse 4.13 + some maven dependency, here is my pom.xml :

While I am using cucumber with Maven in eclipse, it is not recognizing #given,#when, #then tags. The versions used are java1.8, eclipse oxygen,maven integration to eclipse 1.5 and cucumber eclipse plugin 0.23.
Gherkin syntax is getting recognized if am not using Maven and code is running well.I tried using same versions of dependencies in pom.xml file. But still it is not importing import cucumber.api.java.en.; and throwing error.
Below is the pom.xml file for reference.

However you have not shared pom.xml. but It happens when we mix direct & transitive dependencies. So we shall not mix direct & transitive dependencies specially their versions! Doing so can cause unpredictable outcome. Below are few errors being reported by people due to wrong use of dependencies.
The import cucumber.api.junit cannot be resolved
java.lang.NoClassDefFoundError: gherkin/IGherkinDialectProvider
import cucumber.api.DataTable; cannot be resolved
Solution: You can add below set of minimal cucumber dependencies. In case you are using info.cukes dependencies, please start using io.cucumber dependencies as
info.cuke is is pretty old dependency having last version as 1.2.5 and no support is being provided after September 2016 and
io.cucumber is the latest one having version from 2 - 4.3 where we can see all the latest updates from Cucumber team
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-junit</artifactId>
<version>4.3.0</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-picocontainer</artifactId>
<version>4.3.0</version>
<scope>test</scope>
</dependency>

I tried this in my POM.XML and it's works:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

Add JAR files to a project in Eclipse using Maven

I am trying to add certain JAR files, related to the Spring Framework, required for a project using Maven.
Project Name: Spring
Is it possible to do this using Maven?
The dependency is as follows:
<!-- https://mvnrepository.com/artifact/org.springframework/spring-aspects -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>3.2.7.RELEASE</version>
</dependency>

You should import the project as a Maven project. If it is not a Maven project you can convert it using Eclipse.
And then you should put your dependency as one of the dependencies in the pom.xml of the project like this:
<dependencies>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-aspects -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>3.2.7.RELEASE</version>
</dependency>
</dependencies>

You don't need to add JAR files manually. Maven will do it for you. You just need to define dependency in pom.xml.
Following is an example pom.xml:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

<artifactId>com.spring.test</artifactId>

</properties>
<dependencies>
<dependency>

Adding hibernate dependency in Eclipse with Maven and m2e plugin

I've created a Java project in eclipse and added hibernate 3.5.4 dependency to pom.xml file, but the only jar that appeared in Maven Dependencies tab is slf4j-api-1.5.8.jar. How should I configure Maven or m2e plugin to add all required dependencies for Hibernate?
My pom.xml file:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<artifactId>HibernateTutorial</artifactId>
<version>0.0.1-SNAPSHOT</version>
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.3</source>
<target>1.2</target>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.5.4-Final</version>
<type>pom</type>
</dependency>
</dependencies>
</project>

When specifying a dependency with <type> pom it won't be included into your dependencies library as you are expecting (a jar file).
Here is a list of basic hibernate artifact ids that I use to include:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate.common</groupId>
<artifactId>hibernate-commons-annotations</artifactId>
<version>${hibernate.version}</version>
<classifier>tests</classifier>
</dependency>
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
Replace the ${hibernate.version} with desired version or define a property with this identifier.

Building maven project in Bamboo gives me an empty jar

I'm working with Eclipse, Maven 2.0 and Bamboo. I checked out a project from GitHub and debugged it in Eclipse. I had it ready and when I exported the JAR from Eclipse I got a 76KB JAR (which is correct), but when I make Bamboo use a plan to build the same JAR using a maven pom.xml file, Bamboo gives me a 1KB JAR saying there's nothing to compile.
What am I missing? Here's my pom.xml file:
