Compare Maven vs Gradle Commands

If we observe both Maven’s pom.xml and Gradle’s build.gradle file, we can find the following things

Compare Maven and Gradle Build Script Major Elements:

MAVEN ELEMENTS	GRADLE ELEMENTS
<groupId>	Gradle’s “group” Element
<artifactId>	Gradle’s “baseName” Element
<version>	Gradle’s “version” Element

Maven and Gradle Commands In Brief:

The following table lists all useful, frequently used and important commands.

MAVEN COMMAND	GRADLE COMMAND
mvn package	gradle assemble
mvn test	gradle test
mvn clean	gradle clean
mvn –help	gradle –help
mvn install	gradle install
mvn –version	gradle –version

#1

1	mvn --version

To know version of gradle, we need to use the following Gradle command:

1	gradle --version

#2

1	mvn package

To create JAR/WAR/EAR, we need to use the following Gradle command:

1	gradle assemble

#3

1

mvn test

1	gradle test

#4

1	mvn -DskipTests=true install

1	gradle -x test install

#5

1	mvn test package

1	gradle build

#6

1

mvn clean

1	gradle clean

To deploy WebApplication
To deploy application WAR/EAR file into server, we need to use following commands.

1	mvn deploy

To run on Jetty Embedded Server

1	mvn jetty:run

Gradle has separate commands for each server to run created WAR/WAR file.

To run our WebApplication with already created WAR file in an Embedded Jetty Server:

1	gradle jettyRun

To build WAR file, deploy and run it in an Embedded Jetty Server:

1	mvn jetty:run-war

1	gradle jettyRunWar

NOTE:- We will see one separate post for WebApplication Development and run with an Embedded Jetty Server. Please see my upcoming posts.

To create JAR file
To create JAR file from compiled class files, we need to use following command.

1

mvn jar

1 2 3 4 5

gradle jar   or   gradle libs

Eclipse IDE Commands
To Generate a Project and all Eclipse required files

1	mvn eclipse:eclipse

1	gradle eclipse

To clean all Eclipse required files

1	mvn eclipse:clean

1	gradle cleanEclipse

Install Gradle Project To Maven Repo:

We can use “gradle install” command to build and install our application JAR/WAR file to our Local Maven Repository.

We cannot execute “gradle install” command with our previous Gradle project example from “Gradle Spring MVC Simple Application” because we have not specified any Maven plugins in build.gradle file.

Now we will change our build.gradle file to include this functionality. Please follow these simple steps

• Add maven plugin to build.gradle file

1	apply plugin: 'maven'

• Add GroupId and our JAR/WAR file version
Add build.gradle file file root elements as shown below

1 2	group = "com.journaldev" version = "1.0"

If we don’s specify version element here, then it uses war file version declaration as shown below

1 2 3 4

war {     baseName = 'SpringMVCExample'     version = '1.0.0-BUILD-SNAPSHOT' }

That’s it dude.
• Our complete and new build.gradle file

apply plugin: "java" apply plugin: "eclipse" apply plugin: "war" apply plugin: 'maven'    sourceCompatibility = 1.7   group = "com.journaldev" version = "1.0"   war {     baseName = 'SpringMVCExample'     version = '1.0.0-BUILD-SNAPSHOT' }    repositories {     mavenCentral() }   dependencies {     compile("org.springframework:spring-context:4.0.0.RELEASE")     compile("org.springframework:spring-webmvc:4.0.0.RELEASE")     compile("org.aspectj:aspectjrt:1.7.4")     compile("javax.inject:javax.inject:1")     compile("javax.servlet:servlet-api:2.5")     compile("javax.servlet:jstl:1.2")     compile("javax.servlet.jsp:jsp-api:2.1")        compile("org.slf4j:slf4j-api:1.7.5")     compile("org.slf4j:jcl-over-slf4j:1.7.5")     compile("org.slf4j:slf4j-log4j12:1.7.5")     compile("log4j:log4j:1.2.15")       testCompile("junit:junit:4.7") }

• Execute “gradle install” command
