Maven shade plugin cannot resolve javax.jnlp

Question

I'm trying to package my project with shade plugin, but getting the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:2.1:shade (default) on project HiveBrowser: Error creating shaded jar: Could not resolve dependencies for project HiveBrowser:HiveBrowser:jar:1.0: Could not find artifact javax.jnlp:jnlp:jar:1.6 in central (http://repo.maven.apache.org/maven2) -> [Help 1]

Here is my pom build plugins entry:

Answer 1

<scope>system</scope> breaks the dependency mechanism.

If you cannot find it in a repository accessible to you, I would suggest you install the jar you have in your own repository and remove the scope tag.
