To install locally:
$ mvn install -s .settings.xml
and to deploy snapshots to repo.spring.io:
$ mvn deploy -DaltSnapshotDeploymentRepository=repo.spring.io::default::https://repo.spring.io/libs-snapshot-local
for a RELEASE build use
$ mvn deploy -DaltReleaseDeploymentRepository=repo.spring.io::default::https://repo.spring.io/libs-release-local
and for jcenter use
$ mvn deploy -DaltReleaseDeploymentRepository=bintray::default::https://api.bintray.com/maven/spring/jars/org.springframework.cloud:build
and for Maven Central use
$ mvn deploy -P central -DaltReleaseDeploymentRepository=sonatype-nexus-staging::default::https://oss.sonatype.org/service/local/staging/deploy/maven2
(the "central" profile is available for all projects in Spring Cloud and it sets up the gpg jar signing, and the repository has to be specified separately for this project because it is a parent of the starter parent which users in turn have as their own parent).
