手动下载和安装maven插件

Question

I am on proxy network and proxy is preventing maven to connect to central repo

Is there any way to download the maven plugins manually and installing the plugins in local .m2 repo.

Thanks

Answer 1

If you have the jar, you can use :

mvn install:install-file -DgroupId=<your_group_name>  \
-DartifactId=<your_artifact_name>  \
-Dversion=<version>  \
-Dfile=<path_to_your_jar_file>  \
-Dpackaging=jar \
-DgeneratePom=true

if you don't have it, and it's not a private arrtifact, you can find the jar and the informations in repository website (for exemple http://mvnrepository.com/ )

Have a look here if you want to configure a proxy for maven. That way you do not need to download the dependencies in any obscure and unreliable way: Howto configure a proxy for Maven

Answer 3

The simplest way to do this is to use any machine that can connect to central to download all repo you need then copy ./m2 manually to your machine with usage of offline flag every build

if your solution is scalable you will need to install nexus or any maven repository on machine can goes outside and you configure maven to see repo machine. and this is the model solution to that case

Answer 4

To install a jar you can use install:install-file to install any kind of jar. But a maven plugin comes with dependencies so you will have to install them. My suggestion would be to copy a .m2 repo from a machine with access to the internet (for maven).
