maven

Example:

pom.xml (Project Object Model.xml file)

#Create project using mvn template.

mvn archetype:generate -DgroupId=org_name -DartifactId=common-abstract -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

#Pass run-time arguments :

mvn spring-boot:run -Dspring-boot.run.arguments="20180414"

#Run in verbose mode :

mvn spring-boot:run -Dspring-boot.run.arguments="20180414" -X

#Run project

mvn clean install

#Package into specified packaging(jar/war) within pom.xml. Supply any required argument using -D, if mvn is allowed to perform tests.

mvn clean package -Dspring.config.location=<APPLICATION_PROPERTY_FILE_PATH>

#List all dependencies

mvn dependency:tree

#Skip tests during build

mvn -DskipTests=true clean install

mvn -Dmaven.test.skip=true clean install

#How to package all dependency for spring-boot. Sources: stackoverflow

1. Use spring-boot-maven-plugin. Add below lines to project tag within pom.xml

     <build>

       <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

                <executions>

                    <execution>

                        <goals>

                            <goal>repackage</goal>

                        </goals>

                        <configuration>

                            <classifier>spring-boot</classifier>

                            <mainClass>com.<ORG-NAME>.app.Application</mainClass>

                        </configuration>

                    </execution>

                </executions>

            </plugin>

        </plugins>

    </build>

2. Build jar using :

mvn -pl <ARTIFACT_ID> clean package spring-boot:repackage

3. Run jar:

java -jar <ARTIFACT_ID>-<VERSION>-spring-boot.jar

#Create sub-projects(library/module(s))

1.make sure, package-type of parent is set to 'pom'. instead of jar, war etc.

2.get into parent project folder & create project(manually or using mvn command(reccomended as it updates pom.xml in parent as well) )

#Work(compile, release, install) on specific module(sub-project or library) using -pl.

mvn -pl <MODULE_NAME> clean install

#Using maven plugins: Sources- maven-plugins :

<project>

  <build>

    <plugins>

      <plugin>

        <groupId>org.apache.maven.plugins</groupId>

        <artifactId>maven-shade-plugin</artifactId>

        <version>3.2.1</version>

        <executions>

          <execution>

            <phase>package</phase>

            <goals>

              <goal>shade</goal>

            </goals>

            <configuration>

              <transformers>

                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">

                  <mainClass>com.<ORG_NAME>.<MAIN_CLASS_NAME></mainClass>

                </transformer>

              </transformers>

            </configuration>

          </execution>

        </executions>

      </plugin>

    </plugins>

  </build>

</project>
