title: maven-compiler-plugin not found
body: <p>I am learning Selenium and I would like to try add the maven-compiler-plugin to pom.xml and reimport maven settings. So I found this example to do it <a href="http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html" rel="noreferrer">http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html</a> and tried to add the code to the pom.xml. But the vrsion from the example 3.8.1 is red like on the screenshot. What it means? It is a copy from example. </p>
