How to get artifacts SHA1 using mvn command

I am using maven to download jar when deploying. I would like to check the checksum of a deployed jar to prevent redeploy of the same version.

Downloading full jar can be made with this command:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:get -DgroupId=com.c.abcd -DartifactId=javaRocket -Dversion=$jar_version -Dpackaging=jar -Dclassifier=shaded -DremoteRepositories=http://repo:8081/nexus/content/groups/public/ -Ddest=C:\\Windows\\temp\\javaRocket.jar -Dtransitive=false

Is it possible to download the SHA1 by similar command or some metadata, where is the SHA1?

When deploying, Maven prints the URLs it uses. If it tells you that it deploys http://.../org/some/artifact/1.0/artifact-1.0.jar, then you should be able to get the SHA1 checksum by downloading http://.../org/some/artifact/1.0/artifact-1.0.jar.sha1 with a web browser or a command line tool like wget or curl. I don't know a Maven command or plugin to download only the checksum.

Maven itself ignores the checksum when it comes to double deployment/download; it only uses the release version (i.e. a version without -SNAPSHOT).
