Maven and Gradle

This is practise project to refreshing springboot development using both maven and gradle. We are going to make a simple web based application and setup a basic manually configuration to understand at command line.

Packages

• spring-boot-starter-web : uses for web applications
• spring-boot-devtools : it restart the development server on each build change, if you are running your project using command mvn spring-boot:run or gradle bootRun without any IDE, use the mvn install or gradle build command after each save on another terminal.

Maven Commands

• Running the app

mvn spring-boot:run

• Install dependency

mvn clean install

• Check the dependency tree

mvn dependency:tree

• Build standlone jar (it will create in folder target/{artifactId}.jar)

mvn package

• Running the standlone app

java -jar {path_to_your_jar_file}

• Environment variable

export MAVEN_OPTS=-Xmx1024m

Steps for Maven Spring boot Project

1. create a folder, choose a name.
2. create a pom.xml file (ref:file:springboot-ex1-mvn/pom.xml)
3. create a javafile MyApplication.java (ref:file:springboot-ex1-mvn/src/main/java/mymvnapp/MyApplication.java)
4. run mvn spring-boot:run

Gradle Commands

• Running app

gradle bootRun

• Check Dependencies

gradle dependencies

• Clean & Install Dependencies

gradle clean build

• Build a standlone jar (build/libs/{name_of_root_folder}.jar)

gradle bootJar

• Run Standlone jar

java -jar {path_to_jar_file}

• Environment Variables

export JAVA_OPTS=-Xmx1024m

Steps for Gradle on Spring boot

1. Create a folder
2. Make a build.gradle file (ref:./springboot-ex2-gradle/build.gradle)
3. Make a MyApplication.java file (ref:./springboot-ex2-gradle/src/main/java/MyApplication.java)
4. Run the application using gradle bootRun
