[maven-2] How can I download a specific Maven artifact in one command line?

I can install an artifact by install:install-file, but how can I download an artifact?

For example:

mvn download:download-file -DgroupId=.. -DartifactId=.. -Dversion=LATEST

Regarding how to get the artifact binary, Pascal Thivent's answer is it, but to also get the artifact sources jar, we can use:

mvn dependency:get -Dartifact=groupId:artifactId:version:jar:sources

e.g.

mvn dependency:get -Dartifact=junit:junit:4.12:jar:sources

This works because the artifact parameter actually consists of groupId:artifactId:version[:packaging][:classifier]. Just the packaging and classifier are optional.

With jar as packaging and sources as classifier, the maven dependency plugin understands we're asking for the sources jar, not the artifact jar.

Unfortunately for now sources jar files cannot be downloaded transitively, which does make sense, but ideally I do believe it can also respect the option downloadSources just like the maven eclipse plugin does.

Here's what worked for me to download the latest version of an artifact called "component.jar" with Maven 3.1.1 in the end (other suggestions did not, mostly due to maven version changes I believe)

This actually downloads the file and copies it into the local working directory

From bash:

mvn dependency:get \
    -DrepoUrl=http://.../ \
        -Dartifact=com.foo.something:component:LATEST:jar \
        -Dtransitive=false \
        -Ddest=component.jar \

The usage from the official documentation:

https://maven.apache.org/plugins/maven-dependency-plugin/usage.html#dependency:get

For my case, see the answer below:

mvn dependency:get -Dartifact=$2:$3:$4:$5 -DremoteRepositories=$1 -Dtransitive=false
mvn dependency:copy -Dartifact=$2:$3:$4:$5 -DremoteRepositories=$1 -Dtransitive=false -DoutputDirectory=$6

#mvn dependency:get -Dartifact=com.huya.mtp:hynswup:1.0.88-SNAPSHOT:jar -DremoteRepositories=http://nexus.google.com:8081/repository/maven-snapshots/ -Dtransitive=false
#mvn dependency:copy -Dartifact=com.huya.mtp:hynswup:1.0.88-SNAPSHOT:jar -DremoteRepositories=http://nexus.google.com:8081/repository/maven-snapshots/ -Dtransitive=false -DoutputDirectory=.

Use the command mvn dependency:get to download the specific artifact and use the command mvn dependency:copy to copy the downloaded artifact to the destination directory -DoutputDirectory.

The command:

mvn install:install-file 

Typically installs the artifact in your local repository, so you shouldn't need to download it. However, if you want to share your artifact with others, you will need to deploy the artifact to a central repository see the deploy plugin for more details.

Additionally adding a dependency to your POM will automatically fetch any third-party artifacts you need when you build your project. I.e. This will download the artifact from the central repository.

one liner to download latest maven artifact without mvn:

curl -O -J -L  "https://repository.sonatype.org/service/local/artifact/maven/content?r=central-proxy&g=io.staticcdn.sdk&a=staticcdn-sdk-standalone-optimizer&e=zip&v=LATEST"

To copy artifact in specified location use copy instead of get.

mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.2:copy \
  -DrepoUrl=someRepositoryUrl \
  -Dartifact="com.acme:foo:RELEASE:jar" -Dmdep.stripVersion -DoutputDirectory=/tmp/

LATEST is deprecated, try with range [,)

./mvnw org.apache.maven.plugins:maven-dependency-plugin:3.1.1:get \  
-DremoteRepositories=repoId::default::https://nexus/repository/maven-releases/ \
"-Dartifact=com.acme:foo:[,)"

One could use dependency:copy (http://maven.apache.org/plugins/maven-dependency-plugin/copy-mojo.html) which takes a list of artifacts defined in the plugin configuration section and copies them to a specified location, renaming them or stripping the version if desired. This goal can resolve the artifacts from remote repositories if they don't exist in either the local repository or the reactor.

Not all the properties of the plugin could be used in maven CLI. The properties which have "User Property:" property defined could be specified. In the below example I am downloading junit to my temp folder and stripping the vesion from the jar file.

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:copy -Dartifact=junit:junit:4.11 -DoutputDirectory=/tmp -Dmdep.stripVersion=true

where artifact=junit:junit:4.11 is the maven coordinates. And you specify artifcat as groupId:artifactId:version[:packaging[:classifier]]

With the latest version (2.8) of the Maven Dependency Plugin, downloading an artifact from the Maven Central Repository is as simple as:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=groupId:artifactId:version[:packaging[:classifier]]

where groupId:artifactId:version, etc. are the Maven coordinates

An example, tested with Maven 2.0.9, Maven 2.2.1, and Maven 3.0.4:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=org.hibernate:hibernate-entitymanager:3.4.0.GA:jar:sources

(Thanks to Pascal Thivent for providing his wonderful answer in the first place. I am adding another answer, because it wouldn't fit in a comment and it would be too extensive for an edit.)

Here's an example to get ASM-7 using Maven 3.6:

mvn dependency:get -DremoteRepositories=maven.apache.org -Dartifact=org.ow2.asm:7.0:sources:jar

Or you can download the jar from here: https://search.maven.org/search?q=g:org.ow2.asm%20AND%20a:asm and then

mvn install:install-file -DgroupId=org.ow2.asm -DartifactId=asm -Dversion=7.0 -Dclassifier=sources -Dpackaging=jar -Dfile=/path/to/asm-7.0.jar
