Just need to add Maven plugin to build.gradle
Then run the command 'gradlew.bat install'
The pom file for maven build will be available under build/poms named 'pom-default.xml'
Copy the 'pom-default.xml' to build.gradle directory and rename to 'pom.xml'.
Now you can build project by maven command 'mvn clean install'
Indicate Java version
If the build is failed due to 'diamond operator is not supported in -source 1.5 (use -source 7 or higher to enable diamond operator)', you need to add 'maven-compiler-plugin' to the pom file and re-run command 'mvn clean install'
