Creating a maven repository

create_maven_repo.sh

### Create Maven Repository
#Create a directory named mavenrepo
mkdir mavenrepo

#Move into the dir
cd mavenrepo

#Initialise with git
git init

#Add remote repo
git remote add origin git@github.com:<username>/<mavenrepo>.git

#Create releases and snapshots dir 
mkdir releases snapshots

#Create README.md under each dir
touch releases/README.md
touch snapshots/README.md

#Git add all files
git add .

#Git commit with a msg
git commit -m "Initial Setup"

#Push to remote
git push origin master

### Generating maven artifacts
mvn clean org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file -DgroupId=com.company.id -DartifactId=artificat-id -Dversion=1.0.0 -DpomFile=pom.xml -Dpackaging=aar -Dfile=artifact.aar  -DlocalRepositoryPath=./mavenrepo/releases/aar -DgeneratePom=true -DcreateChecksum=true

### Adding and pushing artifacts to remote maven repo
git add .
git commit -m "<artifact> v1.0.0 added"
git push origin master

How do I generate the pom file? The default one generated in ./gradlew assembleRelease isn't accepted by mvn
