Everything related to understanding of gradle. This repo is used to learn about Gradle and Git repo creation in local and pushing it to Github.

Gradle has 3 main thigns:

• What app to build?
• what dependency to include/use to build and dependency management system?
• Additional actions to take (tasks)?

gradlew uses a downloaded version of gradle instead of a locally installed gradle. This helps every developer running this project to build it with same gradle version in their local machines

Hierarchy:
Project -> Build script -> Tasks & plugins

gradlew tasks - list all tasks
plugins help with adding new common tasks that many generally use; extends gradle core capabilities

Important things about groovy used by Gradle:
1. Parenthesis after method are optional unless there are no arguments in which case they are required
- So id 'java' and id('java') both are same
2. Everything is a class and method and the start is org.gradle.api.Project class [https://docs.gradle.org/current/javadoc/org/gradle/api/Project.html]
3. {} brackets are closure like lambda expressions that you pass to a method as argument
4. Some methods take Map as argument
- Like attributes('Main-class':'com.example.tutorial.GradleTutorial')
- Again above line is same as attributes 'Main-class':'com.example.tutorial.GradleTutorial'
- ap is created without having to use new keyword here

How project is created:

• Started the project creation by running gradle init. Chosen options it has given.
• Then updated build.gradle file with required tasks for the present simple java project
• Then added src/main/java and src/test/java folders and added simple java file
• Then added testing with junit5
• This also list all Gradle tasks programatically written in build.gradle
• Explored tasks creation, println and groovy syntax i.e. parenthesis, closures

To push to git:

• Created a new repo with same name as project name on github.com
• In local ran git init
• configured git in local with username, email; this is a must
• Added repo urlgit remote add origin <REMOTE_URL>
• Created personal token on github.com
• Then added and committed the files and pushed git push origin master
• Git asks for credential manager to use. Add token here when prompted.

Build fat jar:

• Addfrom { configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) } } to copy classpath to the jar

//TODO - Multi-module projects:

• Build 2 modules
• Apply common gradle settings
• Apply common gradle build configs
• Build each module independent and together
• Move dependencies to external dependencies file and immport
