	<!--
	Useful Maven commands:
	To exclude specific submodules (in particular those with unresolvable dependencies such as JDK Device I/O) use the -pl '!submodule-a' option, e.g.:
		mvn -pl '!diozero-provider-jdkdio10,!diozero-provider-jdkdio11,!diozero-imu-visualiser' package
	Skip tests:
		-Dmaven.test.skip=true
		-DskipTests
	General lifecycle:
		mvn package
		mvn install
		mvn deploy
	Show updates to versions:
		mvn versions:display-plugin-updates
		mvn versions:display-property-updates
		mvn versions:display-dependency-updates
	Updates properties to latest versions:
		mvn versions:update-properties
	Dependency analysis:
		mvn dependency:analyze
	Set new project version:
		mvn versions:set -DnewVersion=0.5-SNAPSHOT
		mvn versions:commit
	Licence stuff:
		mvn license:update-project-license
		mvn license:update-file-header
	Push to repository:
		mvn deploy
		mvn deploy -P release
		(go to https://oss.sonatype.org/#nexus-search;gav~com.diozero~diozero-core~~~~kw,versionexpand
		then Staging Repositories close and release)
	Release (can't get this to work correctly, messes up version numbers by deploying with the old snapshot version):
		mvn release:prepare -DignoreSnapshots=true
		mvn release:rollback & mvn release:clean 
		mvn release:perform
	Current release process (see http://central.sonatype.org/pages/apache-maven.html):
		Update version:
			mvn versions:set -DnewVersion=xxx
			mvn versions:commit
		Check-in pom.xml files modified by mvn versions.
		Build and push:
			mvn deploy -P release
		Add tag:
			mvn scm:tag diozero-xxx
		Alternatively:
			git tag -a diozero-xxx
			git push origin - - tags
		To delete a local and remote tag:
			git tag -d <tag>
			git push origin :refs/tags/<tag>
		Update version to next SNAPSHOT version:
			mvn versions:set -DnewVersion=yyy-SNAPSHOT
			mvn versions:commit
