using maven to fetch code from git + perform build + package into a jar + finally zip the complete folder containing jar and resources

Question

Hi from past 3 days i have been looking for a solution for my requirement but not getting help it will be great if someone can give me an idea how to go about it

my requirement:

i have source code in git in below structure:

Toolcode
 - sources
   - src
     - main/java/.*java
     - main/resources

 -lib
   - all dependencies like log4j etc

i want to fetch this code on my local machine and then refer the src and lib folder and build the code and package it as jar and place in a new folder called LIB and finally zip this folder LIB .

Can this be done using one single pom.xml file?

Answer 1

maven 3 build type does this

<modelVersion>4.0.0</modelVersion>
  <groupId>projectgroup</groupId>
  <artifactId>projectname</artifactId>
  <version>0.1</version>
  <packaging>jar</packaging>

use this in pom.xml all this is done while creating project itself

Answer 2

Below pom.xml would build as you which. With mvn package you can generate a Jar file ./lib/Toolcode-1.0-SNAPSHOT-with-dependencies.jar which contains all dependencies.

As long there is not a compelling reason to do so I would propose to use the Maven standard directory structure.

structure of directory Toolcode before build

./pom.xml
./sources/src/main/java/sub/optimal/toolcode/Main.java

class and jar files created by mvn package

./lib/classes/sub/optimal/toolcode/Main.class
./lib/maven-archiver/pom.properties
./lib/Toolcode-1.0-SNAPSHOT-with-dependencies.jar
./lib/Toolcode-1.0-SNAPSHOT.jar

pom.xml (for non default directory structure)

<?xml version="1.0" encoding="UTF-8"?>
