Gradle Support #107

[balajiv113]

The following updates are done to the existing pull request #149

• Support for atomic release (Previously each modules will be released individually)
• Support for uploading artifacts to nexus

Prerequisite

• Below environment variables should be configured,
  SONATYPE_NEXUS_USERNAME
  SONATYPE_NEXUS_PASSWORD

Command
Execute the following command to start release build,

gradlew release -Drelease.useAutomaticVersion=true

The following changes are done automatically by this command,

• Build the complete project (including all modules)
• Creates a release tag (tag format - sirix-{version}>) in the head
• Updates the gradle.properties file to next snapshot version
• Push the following changes to git repository
• Publishes all the generated jars (Eg: sirix.jar, sirix-sources.jar, sirix-javadoc.jar) to nexus repository.

Note

• Command line git push should not prompt for username and password. This can be verified by just running git push and validate whether username and password is not prompted
• In order to skip any task use -x and the task name.
  Eg: To exclude publishing of jars to nexus,
  gradlew release -Drelease.useAutomaticVersion=true -x uploadPublications
