``++system++`` dependencies are sought at a specific, specified path. This drastically reduces portability because if you deploy your artifact in an environment that's not configured just like yours is, your code won't work. 

== Noncompliant Code Example

----
<dependency>
  <groupId>javax.sql</groupId>
  <artifactId>jdbc-stdext</artifactId>
  <version>2.0</version>
  <scope>system</scope>  <!-- Noncompliant -->
  <systemPath>/usr/bin/lib/rt.jar</systemPath>  <!-- remove this -->
</dependency>
