How to get specific version dependencies jars from maven artifactory repository who has “Provided” scope

Question

Is it possible to get specific version dependencies jars from maven artifactory repository who has "Provided" scope after the build.Due to so many webapps and most of them having common dependencies, thought of making all dependencies as "Provided" (So that WEB-INF/lib would be empty) and getting all "provided" jars of specific version from the artifactory repository during deployment (Very first step of deployment is copying the jars in to Tomcat common lib followed by war deployment).If possible please help me by giving model script to do the copy from repository to tomcat common lib before deployment.

Assume app having 3 webapp (webapp1,webapp2 and webapp3) and all using abc1.jar,abc2.jar,abc3.jar.each webapp classloader loading all these 3 for each war to deploy.Instead making them as provided and keeping 3 jars in Tomcat common lib would be appropriate i feel.Now my question is after the maven build, can i get provided jars from repository to copy them from repository to tomcat lib using shell script

Answer 1

When the idea is, to create an archive, which contains the jars, that are marked with the scope provided in the pom.xml. So if multiple web-apps use these same jars, they can be deployed to the central place in the wen container provider (Tomcat / Jetty / JBoss / etc).

For as far as I know there is no option in Maven to create an archive, for these provided dependencies. Or some other way to extract them easily from the Maven repository.

A question rises Why would you do so? Many projects move these days to Docker or similar solutions. Which deploy just one web-app in one container. So no need for the complexity of searching for commin libraries and placing them upfront on the web container. Etc etc.

Another question Why add complexity. An easier set-up is to add all depended jars to the web-app. As disk space and network speed / capacity, is most of the time not an issue.

Seems the answer Getting jars from scope provided maven web project is already provided

TIP The above sample, shows the usage of the maven-dependency-plugin. It is configured to run during the phase package (<phase>package</phase>).
Use mvn clean package, to let it do it's task.

The pom.xml needed a few small modifications:

• This is just a small pom.xml, so package should be pom, as there is no web-app content, Java classes, configuration etc.
• In build, the finalName is not needed.
• Updated dependency postgresql it's scope with value provided, so at least one dependency is resolved, by the plug-in
• Removed pluginManagement which should be used in parent-pom cases, not here. Here it just hides the plug-in. In cases where it is used, the parent-pom defines the plugin configuration for multiple Maven projects. All projects which use the same parent-pom, can include a plugin, with the same version number and configuration, as given in the parent-pom.
