Maven libraries as source in assembly file

[abiondo84]

Hi, i'm new to vscode. I created this assembly file to deploy a java webapp in tomcat:

{
"mappings": [
{
"source-path": "src/main/webapp/",
"deploy-path": "/"
},
{
"source-path": "target/classes/",
"deploy-path": "/WEB-INF/classes/"
},
{
"source-path": "........",
"deploy-path": "/WEB-INF/lib/"
}
]
}

Which source path i should use for maven dependency libraries?
I need to call a maven plugin to download jars first, or is there an option (in this extesion or language support extension) to do it automatically on pom changing?
