I am trying to build https://github.com/mrniko/redisson
When I run mvn, it gives a error
No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format : or :[:]:. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-site, site, post-site, site-deploy, pre-clean, clean, post-clean. -> [Help 1]
If I use something random mvn deploy, the jar files are created in the target folder, but

Just curious, what is the correct mvn command ?
Maven is a build tool which by itself doesnt know anything unless you specify using command line or set some defaults in pom.xml
You should typically use "mvn clean install" as mentioned earlier too to generate the necessary executable
"deploy" goal is used to push your jar/artifacts to the MAVEN REPO which is a different server - this server holds artifacts and is not a SCM like github or SVN So as the ERROR indicates you need to specify the details of the MAVEN REPO server in your POM file or in the setting.xml file of your maven execution
