STEP 1 >

STEP 5 >
Project structure in Eclipse>
pom.xml is the deployment descriptor file.
pom.xml looks like this >
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>com.ankit</groupId>
<artifactId>MyMavenProject</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>MyFirstMavenProject</name>
<description>This is MyFirstMavenProject</description>
</project>

STEP 5.1 >
Currently it is not a java project 
(J icon is missing)
(J icon is missing)
We will make it java project 
(Observer carefully : You can see J icon - This j indicates that it's a java project)
(Observer carefully : You can see J icon - This j indicates that it's a java project)
STEP 5.2 >
Now, Project structure in Eclipse>
You can see that JRE System Library is added now.
If in case you face this error - Source folder is not a Java project - in eclipse. Click here to solve it.
STEP 6 >
Adding dependencies in 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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.ankit</groupId>
<artifactId>MyMavenProject</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>MyFirstMavenProject</name>
<description>This is MyFirstMavenProject</description>
<dependencies>
<!-- Add dependency -->
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.2</version>
</dependency>
<!-- You can add more dependency -->
</dependencies>
</project>
|
STEP 7 >
Now, Right click on pom.xml > select Run As > Then Maven clean
Now, Right click on pom.xml > select Run As > Then Maven install
Refresh the project (F5 or by doing right click on project) - Required only if dependency are not updated.
Right click on project - Maven - Update Project.. (Alt + F5) - Required only if dependency are still not updated.
STEP 8 >
Now, add New Java Class - MyMainClass
And run it as Java Application
package main.java;
import org.apache.commons.lang.StringUtils;
public class MyMainClass {
public static void main(String[] args) {
String str = "abcd";
System.out.println(StringUtils.isAlpha(str));
}
}
/* Output
true
*/
|
Output is > true
You can see that jar (apache-commons) which contains org.apache.commons.lang.StringUtils was loaded just by defining its dependency in pom.xml and then following step 7.
